Manufacturer of my valve, Hunter, said to use Teflon tape on the threaded connection. I would also recommend dry fitting the pvc and marking the full insertion position on the pipe with a marker. That way you can tell if you have pushed the pipe down fully.
I cant seem to fully dry fit my pipes and couplers any suggestions? Thx
I put Teflon tape and it’s still leaking even though I torqued it. Maybe I torqued it too high?
Use teflon tape on the threads. Also use PVC primer before applying glue.
Yes sir bought printer today in a package deal w cement for 5$
Take it to the next level and use pipe dope, tape, then dope again for threaded fittings. Also use a fine sandpaper or emory cloth to take the finish off the pipe, then primer, then cement. No leaks...
@@LogicofChaos7871 Yep. I have done a thousand of them exactly described. I have also been told that pipe dope and tape are not needed with PVC and I know pros who swear by that claim. They say they have done hundreds/thousands of joints over decades and no leaks w/o dope or tape. I sleep better with the dope/tape/dope method. I have never known anyone who joined PVC w/o primer.
@@JohnnyC10071959 I have had one leak in 14 years. It was on what should have been a mirror weld. No mirror....pinhole leak
@@JohnnyC10071959 it’s always better to do the most especially if you’re in the landscaping business and fix a lot of these like myself I do all these extra steps so the clients are sure about what I’m doing and they won’t be saying anything like “oh you only cut the pipe and glue the other one on and you’re charging me this much” but if your doing it at your own home or a buddys all those steps aren’t required
Would have been nice to see the addition of the 3/4 to 3/4 female unions on the pipe coming from the ground. Also, always use primer before the glue, as it makes a better seal and teflon tape on the threads for a better seal. Really liked removing the cylinoid first before removing the old valve as I'm not too nifty with the wires.
Nice job man I liked that idea with the clamps !
Just a heads up, you should apply PVC primer, let it sit for a few minutes before applying the glue. The primer softens the PVC so you get a solid perfect joint. And you should apply glue to both sodes of the joint....ie, fitting and pipe
Also, you should be using Teflon tape on the plastic threads. Maybe not required, but good practice.
I am sure for the little water pressure that runs to our homes it should be fine the way you did it. But, regardless you should know the right way, especially if you are making a DIY video. As a 20yr Union Pipefitter, I have had lots of practice.
Thanks. I use primer as my pipe/fitting depth guide.
Is there a clear primmer all I have is purple primer and clear glue
@@arrealhandymanservice4459 They do have a clear primer, your local big box store should carry it. If not a plumbing outfit would.
www.amazon.com/Oatey-30751-House-Primers-Clear/dp/B004SMUJWA/ref=asc_df_B004SMUJWA/?tag=hyprod-20&linkCode=df0&hvadid=193128962117&hvpos=1o2&hvnetw=g&hvrand=11799944504939371826&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9061283&hvtargid=pla-340660674924&psc=1
WestCoastMods yes I checked I picked up the purple primer and the red hot I just don’t like how messy it looks after so I found clear cleaner and clear glue.. I’ll try an actual plumbing supply hope they have clear and also quick drying and good to use while wet.
I would also recommend the teflon tape, just to be on the safe side. If you have a leak in the threads, will need to cut the pipes and start over..
Thanks for the demo and info, I was about to hire a contractor, but after watching your video, I think I can do this! lol
Oh BTW, did you replace all 3 valves or just one? Do I need to replace all 3 for compatibility?
Couple things I noticed. First, I can buy those at my local Home Depot, and they have pretty good ratings. I bought a couple to replace my brass ones instead of rebuilding them. Secondly, they recommend you somehow attach the pvc to the inlet side and try it first to check for leaks before assembling the outlet side. I haven't figured out how to do that part yet. Anybody have suggestions, that would be great. Other than that, thank you for the video. It helped me out, especially using the clamp.
Good job. Thanks for showing us the work to do our own work. Kudos really expz work for the laymen
Thank you fo r the help, saved me $500 and only took an hour!
Awesome! Nice work!
without reading the instructions on the pvc glue, I recall quarter turns on fittings to make certain the glue contacts fully. I probably would have spun those unions, and sanded them a bit. maybe that's a bit more belt and suspenders... thanks for posting the video!
A lot easier to replace valves if you put a union in the "out" side when valves are originally installed
Thanks for this tutorial video. This helped out a lot!
Thank you for sharing your experience, other channels make it seem super complicated.
Just a note to wrap the male threads of the PVC adapters with teflon tape or a bit of clear silicone. Without it those threaded connections are going to leak.
Excellent video and advice. I hate the Teflon tape so I use the tube of Teflon. Easier for me. I also don’t like the PVC cutters so I use a sawsall with a metal blade And then clean the burs off with a piece of sandpaper.Easy Peezy
Clear and thorough instructions!
2:39 Before you unscrew the solenoids, you may want to mark them with something like #1 , #2, and #3 and restore them later so afterward the signal from the valve timer still goes to the correct valve.
Very good point!
This is excellent! I have to do just one valve but this will save me a lot of money!
Awesome! Glad we could help out!
Thanks, excellent tutorial
A key omission from this otherwise excellent DIY video was to insure the flow direction of the water from supply to sprinkler heads in the lawn/garden. Flow is marked by arrow typically on the underside of the valve. Installing the valve incorrectly that is in opposite flow of the water will result in water flushing constantly from the anti siphon valve cap.
Your Video was excellent. I also took advice of "Just me " in adding a teflon tape to the groves before threading the valve. I also used primer.
This is the first time I attempted to replace the valve and I just completed it. Here are some f the issues I face as a novice first time installer. You have to deep deep and a big circumference if you want to use the pipe cutter to cut the pipes coming out of the ground. I was not able to cut it properly. so I had to use my drummer tool, to make it even and sand the top. So that no debris go into the pipe I stuffed it with cloth which I removed after all the sanding, cutting, planing was done. So being new at this, I had to do extra work to make smooth and level. Also I might have used too much glue, i don't know what is too much but my glue application was dripping slightly. I also found the old pipe coming out of the ground had glue drippings, hence I had to sand it , with a sand paper as well as my dremel kit. It took me 2 hours more than it would have taken a professional. But I must say, this excellent video gave me the courage to complete the installation of the new valve. That valve was I believe defective , because any time I opened any zone , that defective zone always went on and the sprinklers came alive, I just turned on a few zones to check if the problem was solved and Eureka it was solved, Installation successful. I want to let the readers know, this is not an easy task.... not at least the very first time. I had all the tools and I am also an engineer by profession. I have 40 Valves in my property, thank you for saving me a ton of money.
piano wires are nice for the digging part. u don't have to dig as deep and no awkward positions while cutting
Well done man! Thank you for putting this one together!
I have received 2 quotes a job like this. My regular gardener said he'd do it for $150. Some local contractor I found online said he'd do it for $650!
I went with Orbit since my sprinkler system uses Orbit controller and these cost a lot less than Rainbird and have six year warranty. Good call about doing cleanup of the area before install. I had a bunch of bamboo bushes blocking easy access to mine and used a pruning blade on my sawzall to remove these as working in the area would be a nightmare with all the bushes in the way.
Here's some tips: know the width of the connections before buying a new valve - some are up to an inch off. Use an in-line connector that will allow you to remove the old valve without having to cut the pipe - orbit has a product or you can use the PVC sharkbite like products. When you buy a valve purchase a diaphragm kit - 99% of the time the diaphragm is the problem and it usually goes out years after the company changed designs so you wont be able to find it (case in point watermaster was bought by orbit thus you can't easily find the diaphragms)
What is an in-line connector?
Thank you. Very clear and easy to follow.
One question: When connecting the wires, how do you know which of the wires on the new valve is the control wire and which is the ground? It looks like they both have the same white stripe.
Doesn't matter on AC valves
Kind of makes you a little bit worried though. Especially if it doesn’t work the next day. I’m gonna let my glue cure and see how it works the next day after about 24 hours.
NICE!!!!!
Thank You for Video.
Thanks, this is just what I needed.
Also, very important, apply teflon tape to threaded ends that attach to the bottoms of the sprinkler valves. Dont' use tape and you'll have a leak, guauranteed.
thanks was going to call a landscaper , but now I am going to do it .!
👍 awesome!
You need to make sure which is the input and output for the sprinkler valve, meaning that you need to know which of the two pipes the water comes out of the ground from.
You should always prime and cement both ends. Prevents water droplets from coming out.
What does that mean (I'm startinng out/complete novice) but am great at following writeen and verbal instructions
@@soniag4516 what ever part of the PVC pipe touches another needs both primer and cement
Great idea with clamps. I have 2 questions, 1) no primer for pipes before using glue? 2) is tape necessary for pipes that go in new valve?
thank u this video is extremely helpful for me,god bless u
Can the fittings be glued directly onto the existing PVC that was below the cut? That would save several steps and avoid the need to add new PVC, so there must be a good reason that's not being done...
good tips!!
Pro tip, net time put it together and glue the threaded tops on last
Very clean work, good job!
Thank you for this video!
+Theo Campbell thanks for watching!
Very informative. Thank you
I was hoping for something better. I am going to install a coupling fitting in between the pipes and the valve. The next time I need to replace the valve, I can just unclamp the coupling the thread the upper pipes into the new valve.
Union fittings would be a great idea.
Great video Sir! Appreciate you 😊👍
Wow this is great. Amazing that two local sprinkler guys wanted to charge me $700-800 for cheap parts and ten minutes or labor!
Glad we could help!
@@DoItYourselfDad my pleasure- cost me $70 in parts and hour of time. Better than getting ripped off!
What about primer before you glue, and teflon tape for the threaded parts?
Awesome Video. Just noticed tho, that your link to the valve is different from the one you used in this video (solenoid has a handle which i prefer:) but could not find it anywhere. Thanks
Oooops, ok found them, thanks!
Use primer, put glue on both surfaces, hold for about 30 seconds.
The electricity was not brought up.
I assume the electricity was turned off to attach the wires???
Thanks for the video. I would have replaced all of the valves, excavated around the entire area, and brought the valves below the grade using a valve box.
Well thought out video with helpful advise.
The valves need to be higher than the highest
sprinkler head
that's just asking for you drinking water to be contaminated
clutchfan 1 Someones drinking water can get contaminated from valves buried below the frost line; are you kidding me? What does the depth of the valves have to do with groundwater contamination?
Bessie Funk wrong. I have placed many irrigation valves in and everyone of them are below the valve height. Placing them below the grade satisfies several issues, esthetics, mowing and/or weed trimming and moreover, freezing valves.
@@dubs3400 Yes, but it depends on what type of valves you are using.
The Anti-siphon valve must be at least 6" above the highest sprinkler head.
This is common knowledge. It's also city code.
The inline valve can be buried underground. And is more reliable than the anti-siphon valves against contamination due to the additional backflow prevention valve installed also with it.
Thanks, very informative and useful.
I think you forgot to show the part where you glue the joint fittings that go over the cut ends of the pipes sticking off the ground, but it's clear you had them on.
Also, do you use teflon tape on the plastic threads? I've read people arguing one way or the other.
In my case, one valve popped up, water was running all over the place but nothing was broken, it looked like the pressure made the valve pop up, I unscrewed the thread pipe that goes into the valve (where the solenoid is). Should I thread it back to the green valve, then put primer, pvc cement and push it into the pipe that is sticking out from the ground? I hope my explanation made sense.
I think I understand what you’re saying, sounds like when it was first installed it was not installed with enough glue. Yes you should be able to reinstall the valve, just make sure you properly prep the pipes so the adhesive works well.
Teflon tape is highly recommended
great instructions except when gluing, most glues instruct that you apply glue to both ends that you're joining and purple primer is a good idea beforehand. teflon tape on the threaded fittings is never a bad idea.
www.plumbingsupply.com/the-great-pvc-primer-debate.html
I was going to tell him the same thing. Also, the blue glue is not as good as the clear or yellow, but always use primer...
That highschool sophmore recommended cement inside and out as well.. Teflon tape is also needed in this situation, imo.
The link is an interesting read.However there are a lot of practical considerations in the application that aren't accounted for. Two step welding goes back to when primary applications were low pressure DWV systems. So pressure testing wouldn't matter. Longevity of the joint, resistance to intrusion (e.g., tree roots), etc. are of primary importance. If you are looking a CPVC for supply lines, now you have to rethink for pressure strength. Still, not many lines are running sustained 1500 + PSI. The pipe itself probably isn't rated that high (at least for sustained stress -- and what schedule pipe matters also). For a "relatively" pressurized sprinkler line, I think below grade I'd err on the side of two-stage. For above grade, I wouldn't be thinking about how it looks either!
Also, 1/2 turn to distribute the glue, that's it. To get the strongest join, you should insert, then turn... not corkscrew in.
Exactly. Teflon and purple primer are a must.
What state are you in? We've never used these valves just in-lines...
CA, it doesn’t freeze here so we can run them above ground .
I think my landscaper has put in the cheap valves. Need to get nicer ones after my sprinkler turned on by itself after I turned the water back on after replacing the valve stem in my bathroom.
a sudden burst of water to valves can cause the rubber diaphragm inside the valve to seat wrong. Probably not an issue of product more likely you kicked your house water back on to fast and the rush of pressure stuck the valve on.
Forgot to use Teflon tape around the threading where it holds the water🤔
just what I needed!
+Underground LA glad we could help!
Any idea of the height and psi your supposed to go by?
Never done this , that’s way I ask. It’s safe to touch those wires, is there anything that’s needs to be turned off before touching and connecting wires??? Thanks
They are low voltage, so safe to touch. I would still recommend turning off your sprinkler timer though.
When I bleed off the pressure; first step, should it continue to spray water?
It may, if it is, shut off the water supply.
you forgot to use primer on all of your connections before gluing

Which wire is the signal and which one is the ground or does it not matter ? Sorry I’m new at this
How difficult could it have been to test IT ?
Testing these is not difficult, but these were shot and needed replacing.
If you keep cutting the pipe, would that make the mainline pipe shorter and shorter as you replace each valve ?
Yes, that's why we used the extensions. A better way would be to use couplers.
Why are your valves above ground and mine below ground? Installer's choice? Or some design reason?
Valves need to be a minimum elevation above the highest head, and I don’t live in freeze zone.
Does it matter which wire from the new valve goes into the ground and control?
No, it doesn't.
The solenoids are AC powered, so polarity doesn't matter.
What brand and model number were the valves?
Does it matter how high the valve is? Do all the valves need to be a same height?
The valves need ( should) be higher than the highest sprinkler you have on the wine
@@DoItYourselfDad oh okay, thanks!
What causes the anti siphon to leak out water? Everytime the sprinklers shut of the anti siphon leaks out water.
I have an underground valve, inline... the wire came off the top of the solenoid... can i just replae the solenoid? the valve still works? it seems like you just unscrewed the solenoid on yours... presuming they probably all just come off?
Yes you should be able to just replace the solenoid. They’re pretty inexpensive.
@@DoItYourselfDad again not sure if this model even comes off, but are they all the same or should i try and take this one off first to bring to match?
⁰
Teflon tape , and primer is necessary to make sure that will last.
Water continues to float out of pipe at a steady rate after the main irrigation line is off making it difficult to leave blue glue on. What would you suggest?
Let it drain, sounds like you’ve got a lot of residual water in the line.
how do I change out an old isolation irrigation valve, plastic, near the old sprinkler valves (one that controls water flow to sprinkler valves)?
Is the valve your replacing in copper or pvc pipe?
pvc
Im guessing these are 1/4 turn valves, pick up a new valve, a section of the same size pipe and some female to female fittings. You'll also need glue and something to cut with. You'll have to dig far enough around the pipe that you can get some play in it, cut the old valve out and replace it with the new one.
when you put the new valve in the coupler does it have to go all the way down
Question: how do I remove and connect the wires from my old anti-siphon valves sprinkler system to new ones that I install? This to me is the most difficult step. Also my old sprinkler wires are kind of janky and need replacing.
Are they attached with wire nuts?
You might want to remind people to turn off the power to the sprinkler system at the fuse box before re-wiring the system.
yea i was wondering about the electric power..😎
True, I made the assumption that if you are replacing broken valves the timer would be shut off.
24 VAC will not hurt you, but you might get a tingle, and this can only happen if your timer turns the valve on as you are working on it. If you feel better ensuring that no voltage can arrive at the wires, you can simply turn the valve to "OFF" at the control box, or unplug the control unit, (rather than turning everything on your AC circuit off using the breaker at the fuse box).
Nice job. Thank you. I noticed a few mistakes, you forgot Teflon tape on your threaded connector, I think you bought the wrong size valves because you had to squeeze the water input and outflow lines with a clamp and that's going to put pressure on the joints, you have to shop for the right distance and other products because it varies. Lastly, did you really push the valve to seat on the connector? it looks like you got stuck. I'll bet you had to redo it. you should have put PVC on the connector and the pipe before pushing together. I'm not trying to be critical I just made those mistakes before!
Pipe is not bottomed out to the fitting . Primer and glue the pipe and fitting socket .
I hear air coming out of the backflow when valve is off. Is that normal?
What about water still in the pipe ?
Thank you
Great Video,
I am trying to replace the old rainbird APAS-075 valves that parts no longer are available for. Is the valve you are using the Rainbird 075-ASVF? (It looks like a good replacement for my situation). Would this part be any different if bought at a contractor supply store? (There is also a similar DASASVF075 "Profession model" which is all black) Suggestions on which is better?
v/r
Why didn't you show how you connect the bottom of female nut to existing ground pipe?
Where's the primer? What about the tape for the threads? Other than those two critical parts of this video, the rest of the instructions are good. So if you edit, you'll get a thumbs up.
So its ok to mix in a different brand valve ?
Yup, won’t make a difference.
Cause home Depot or Lowe's don't carry the brand I need. And the one I need is triple the price and I was curious if I could just get one similar swap it and the system still be able to control it
@@eleazarfernandez9369 You'll be fine, they all work the same way. Just make sure the pipe diameter and spacing is the same.
@@DoItYourselfDad sweet, I really appreciate the reply. Now I have no excuse to continue to avoid fixing my sprinklers. Thanks
Did all that however when l turn on it doesn't run .When I turn to off setting it runs and auto it runs and does not stop
What can I do to fix this
Good vid on replacing a valve.When you replace the sprinkler valve multiple times like this, you keep shrinking the pipe below the valve. Eventually you run out of pipe because you've moved too low on the pipe or you have too many connectors. This shows how I fixed that, it just shows a fix that prevents the pipe from getting shorter each time: ruclips.net/video/60GpCg6QvJ0/видео.html
Very cleaver! I like it!
video is dead
Hey, does this wire have electricity?
Sprinklers are low voltage wiring.
Another step you failed to mention: Be sure to place the solenoid side of the valve control on the supply line & the vacuum breaker side to the zone side of the sprinkler circuit!
The "know it all" neighbor thought he was a DIY guy & replaced a 4 zone system with all valves installed backwards. It looked pretty & the glue job was solid. But it didn't work. He called me over to figure out the problem he couldn't figure out why it didn't work as it had in the past. He also applied glue to the threads! When he understood his mistake, he realized, DIY was not for him. It cost him double because he had to replace all the valves again. (Didn't leave enough room between the fittings to cut the joiner nipples!) His wife gave him shit about his attempt to "save money" which cost them & took a big ding in the family budget! He wasn't happy! One of those guys you can't tell him anything, always making projects exceed budget & angry with his own ignorance. But he won't get any training for himself because, "HE BELIEVES HE KNOWS IT ALL!" He repeatedly blunders repairs of his own work by not paying attention to critical detail!
I am amused by his stubborn approach until he is IN TROUBLE AGAIN!
I didn’t mention it because all of these valve assemblies have a high arrow showing the direction of flow.... but I guess for he unobservant that doesn’t help....
@@DoItYourselfDad While I have never worked at a "Home Improvement" store, but I have a friend who does. He is a good guy to have a cold beer with once a month or every few weeks. The stories he can tell about many projects which ended in disaster for so many customers who have made a mess of their "money saving" efforts! It is often hilarious to listen to!
My risers are. Male Male so how do I put new valves on turning clockwise the whole valves
That's just a rainbird valve instead of a orbit valve... Can get it really anywhere even Amazon
Should I use tape on the threaded fittings?
The I had are tapered so tape wasn't needed, but it wouldn't hurt.
HELP! My daughter was walking to her car during a really bad thunderstorm and slipped on our green sprinkler system box in front yard. The lid flew off and she fell in all the way up to her thigh. One leg in, one leg out. Her foot came down on a pipe because water was spewing out of it and down our street. A neighbor was able to turn the water off but we need to get this fixed. We have a Rainbird e6c. What is an estimate for a repair like this? We aren't the original installers so unfamiliar with sprinkler systems. Are we talking hundreds or thousands to repair?
Use Teflon tape on threads.
No Teflon tape or PVC primer?
Primer is not needed with all cements.
Hi question I had a gardener change the valve 2 times and it still leaks water off for like 2 3 min after it shuts off why and he said he does not know I paid him 125 to change it and now he referred me to some one else would not give me money back
Introducing the PE valve product video is very good. It can be used in outdoor chemical plants on the coast. It is the best product weapon. It is not affected by the marine climate salt water. Erosion. The product is simple and centralized management. The valve does not need tools by hand. Installation/maintenance Easy. It is also resistant to temperature and pressure. The flow is large. It can also set the flow size. It can be controlled by the remote control of the solenoid valve. The biggest gospel of the buyer.
介紹PE閥產品錄影 非常棒. 可在海岸邊戶外化工廠使用.是最佳產品利器. 不受海洋氣候鹽水影響. 而侵蝕. 產品簡單集中管理.閥用手分解不需工具. 在安裝/保養容易. 又耐溫耐壓. 流量大. 又可設定流量大小.可以用電磁閥遠端控制. 買主最大福音.
Can you just plug them if you don't use the irrigation system?
If you are not planning on using the irrigation system then yes you
could just cap off the pipes. I would suggest leaving everything in
place though and just shutting off the irrigation valve. Our house had a
lawn, I capped all the heads but left the lines in place. These valves
now need a few drip heads I have on my tree's, but we're not watering
any grass anymore.
Wow, I can't believe you actually replied and so timely. Thank you very much! and thanks for the video!
Why didn't you go brass?
nice, although if you're a professional doing it for somebody expect that they'll be pretty upset if you have them poking way up there like that. Not exactly a decorator item.
Anti-siphon sprinkler valves need to be installed a minimum a 6 inches above the highest riser for them to work properly.
I see. Couldn't you dig 6" deeper into the ground, assuming you had 6" below to which to connect?
No, the valve needs to sit 6 inches above the level of the highest sprinkler head, not the line that is underground. If your antiphon valve is installed incorrectly you run the risk of it not working property and the water in the lines backing up into your domestic supply, contaminating the water coming into your house.
I see. So if you're sharing a domestic water supply you're stuck with this. Good to know, thanks. I suspect that's fairly common in some places. Not here. All the valves around here are underground.
On your old one how do u manually turn them on
You back out the small plastic screw.
The one at the very top center or one thats off center. Im new to irrigation i do allot of plumbing but not irrigation thank you for your help
The one that’s off center, don’t back it all the way out, just loosen it a bit and you’ll hear the valve open.
