I already had re-plumbed the pump inlet last week so this is how you do the pump discharge line that sits above the pump. You would plumb both the same way.

NOTES:
This is not a very difficult job, but it does require accurate measurements for the pipes to fit together. The last pipe fitting you do will be the most difficult as that will be the one that will make a complete sealed plumbing. Please plan accordingly so you will be able to fit it on. In this video I was able to move the pump back about 1 inch and slide the last pipe on, then I pushed the pump back completing the plumbing seal. It takes some practice but you can do it. If you make a mistake, simply cut out the pipe or use a new pipe and new fittings. The pipe fittings are not very expensive. All the material for this job will cost you about $20 -$25. Just by extra fittings in case you make an error in your cutting or measuring.
Parts list:
2" MALE ADAPTER THREADED FITTING (for top of pump)
For a better heat rating you can use this pipe also:
2" x 12" nipple cpvc pipe (grey) and rated to 140 degrees
2" SLIP COUPLING
2" PVC PIPE 5 FT
2" SLIP 90 DEGREE ELBOWS
2" FITTING EXTENDER
POOL-TITE GLUE .5PT
Plasto-Joint Stick Thread Sealant 1.25oz 11775 for threaded fitting on top of pump
You can also use plumbers tape
Of course if your pool has 1 ½" pipes adjust the fitting size accordingly.
Pool-Tite Glue Instructions:
Shake can well. Use a primer to clean the pipe fittings (priming step is not needed for non-pressure pipes less than 4" in diameter. Apply liberal coat of cement to pipe depth of the socket, leave no uncoated surface. Apply a thin coat inside if the fitting, avoid puddling, Apply a second coat to the pipe. Assemble parts Quickly. Cement must be fluid. If cement surface has dried recoat both parts. Push pipe firmly into fitting giving it a ¼ turning motion. Hold pipe and fitting together for 30 seconds to avoid it popping out. Glue can get old so if it is gel like don't use it.
You can use the Purple primer or the clear one to prep the pipes. The Purple primer has a very strong dye in it so if you drip it won't come off, so the clear one is less messy.
Sometimes the pump itself will have warped a bit from the heat. In that case the 2" x 12" nipple cpvc pipe will sometimes seal it better.
Here is a look at the pipe online -

You will just have to cut it down to size and then do the repair accordingly.

I'm glad you said it. I don't know when I've seen plumbing that sloppy. Why not take a second and throw a rag around the equipment. We always use medium to heavy bond clear cleaner and cement. Also they make threaded pump mta unions.
I know that made pipe extenders that go into the pipe. But I didn't know that they made them to go over a coupling. Good to know on that. Thanks.
@SPL Thank you! I had a 2" male threaded PVC fitting on the outlet side of a big Hayward Star-Clear Plus pool filter that was leaking and no matter what I tried still kept seeping water. I tried various different kinds and thicknesses of PVC thread tape, pipe dope sealants, and even tried thread tape along with silicone sealer and it still kept seeping/leaking. Then I saw this video and figured what have I got to lose so I picked up a stick of the Plasto-Joint Stick Thread Sealant you used in this video. I cleaned out the female threaded joint in the pool filter and applied the Plasto-Joint Stick Thread Sealant thoroughly inside of it and also applied it thoroughly onto the male threads of the male 2" PVC adapter. The fitting is now sealed perfectly into the pool filter and no longer leaks or seeps any water at all under pressure. This Plasto-Joint Stick Thread Sealant is a life-saver for large, threaded and leak prone large PVC threaded fittings. It seems like the material of the Plasto-Joint Stick Thread Sealant is an almost dry, gooey and very super thick and concentrated implementation of what is in the regular white Oatey or similar pipe sealant compounds that are much thinner and easily brushed on. Anyway all I will ever use moving forward on PVC threaded fittings (especially large ones that seem looser and are more prone to leaks) will be this Plasto-Joint Stick Thread Sealant. Thanks again, you saved me having to buy a new $800 pool filter.
Okay, I over did it on the glue for sure ;). Just didn't want the person copying this to apply too little... glad people can see the humor in it. I get a kick out of all the comments. Twisting is good, couldn't do much while holding the camera. Tripod would have came in handy on this one...
Thanks again for your knowledge dude! You let me know just how easy it will be to change this out. Its just like what I learned to do with my sprinkler pipes. So I already have most of the stuff. I will leave the plastic bags in place until I can get to homedepot to get the rest of the stuff. You saved me much aggravation and money!
I always prime my pipe so the glue gets a good surface to stick to..also i recommend turning the pipe just a little after you glue it so it gets a proper seating.
Thank you, fixing a hot tub and this is exactly what I needed to isolate some leaks temporally to make sure I've isolated them ALL. Before I fix them the right way!! You rock, seriously thank you :)
I think they sell 2" PVC elbows, couplings and 2" PVC Pipes. I don't think they sell the threaded fitting for the top of the pump. You can order the Grainger Nipple, 2 X 12 In threaded fitting online if you needed. Maybe that store is priced high. The 2" x 12" Nipple peice should be around $10.00. The fitting extender if needed is about $8.00. The Elbows ans couplings should be about $2.00 each. Glue should be about $10.00 for .5pt.
Yes, that is a good alternative.
Good video. but wow. the glue is very sloppy. That's a sure way to not get recommended for another job. people don't like seing a mess on equipment.
Yeah, it was one of my first videos. I wasn't using a tripod so i did all the work with one hand. I am smarter now. 😝👍
My first video I did the glue up with my feet, cause I needed both hands for my camera. Great videos. Really
Why don't you use teflon tape? I have to put a threaded male adapter in a inground skimmer would, what would be the best sealant for the threads? Does teflon wear out?
From what I understand Teflon with pvc has some conflict , something about lubricating properties of the tape . I could be mistaken ... if look into though just to be safe!
Thank you for your comprehensive videos! pipes size are all equal for any pump? I have a SP2607X10 Hayward
Not technically. There is 2" or 1.5"
Don't you have to use primer before you but the glue on the PVC pipe?
You mean you are trying to see if the skimmer is the cause of a leak in your pool? If that is why you are testing it you could try to add some drops of food coloring into the skimmer and see if the drops indicate a leak by flowing through it. Depending on your skimmer you can thread plugs into the holes in the bottom, fill it with water and mark the water line. Turn the pool completely off. Check back in 24 hrs to see if the water went down passed the mark.
Yeah, I should rename the video, "Messy Pump Suction Leak Repair." My bad.
Here is the product I use Weldon Pool Heavy 746 PVC Cement Grey (rated for 120 psi). If you can't get this try Weldon 12130 1/2 Pint 704 PVC Cement, Gray.
Why no primer?
I use PVC cement and it doesn't require any primer.
I thought this was a very informative video (though missing some into I found on others) But the filming (the moving around) was very bothersome I had to rewatch trying to take in all the info - also as you know already very sloppy. I did pick up some great info and I thank you for that.
Hi, if the pipes are not snug does that prevent the pump from suctioning the water. My dad did that yesterday, he installed a pump and didn't wait 24 hours, he just turned it on and we still have the same problem, no water coming in, the pressure valve is at 0 and there is a leak it seems on the threaded fitting. Help!
I've been paranoid about the pipe leaking afterwards so I use both the teflon tape x 3-4 and the joint stick
A lot of Home Depots dont sell the Joint Stick. They usually sell the paste. The paste works good too. Also, dont use a hacksaw to cut PVC. Get a pipe cutter, it makes a cleaner cut and you wont have to mess with any burring.
if you would of cut further back on the down part it would of been easier. also how is this a suction leak if your working on the discharge side of the pump?
Hello i just did this repair on my pump and its still leaking from the same spot . Any thoughts?
Good video. What do you think about placing JB Weld Epoxy between the superpump and the beginning of the discharge? I see a small leak that is coming from the pump and seeping around the discharge.
***** Never tried JB Weld on it but it might work. There is a lot of water pressure so not sure. Worth a shot - used JB Weld on a Stainless steel filter and it plugged the pin hole nicely. Good stuff.
Swimming Pool Tips, Reviews & How To -MrDgvb1 Chemical is good to at least 4000 psi. Should hold? And if this does not work a new pump would have to be replaced due to the bonding that has occurred around the discharge from the Epoxy? Or is there a way to get this off and try your method by replacing the pipes?
Ah, found the leak with some shaving cream patched that bad boy up with some epoxy hopefully it holds! Keep up the videos man very informative good job
Ihave a brand new flotec 1 1/2 hp sprinkler pump it runs at 40 lbs about every 2-3 min the pressure will drop to 20 lbs i can hear air in the line then it will come back up tp 40 lbs i have checked for leaks on the suction side and found none I even have wrapped the suction joints with saran wrap no change my neighbor has the same problem with the same kind of pump any Ideas?
Some pool techs use a special PVC glue for pools (you are using Pool Heavy #746). What is the advantage of this type of glue? Can you use standard Oatey PVC solvent and glue?
Use only lesco brand pool pvc pipe,,Lowes sells lesco,it's made for high pressure swimming pool pipes
Thanks for video !!!!
Dude, you made look so simple. now, how can you make it less messy? It's an honest question. You know that sometimes clients are extremely picky in how stuffs looks like.
Don't do it while holding a camera. And paint it after with spray paint. Will be good as new
Thanks for your videos.
can you buy these fittings in lowes or home depot?. very expensive in pool store
There seems to to be too many couplings and elbows. would it be fair to say that cutting out more fittings and using a solid piece will make it a lot easier and lessen the chance of another problem?
+Tim Beausoleil That would be better for sure.
Swimming Pool Tips, Reviews & How To -MrDgvb1 don't get me wrong I am NOT a plumber buy any stretch but I've been in the pool business about 17 years and although I am NOT focusing on the plumbing aspect I know how much of a pain they can become. Thank you for your service and helping others understand how to get jobs done.
Can I get both the suction and discharge fitting from my local hardware store or will I need to purchase it from pool store. The pump is a Pentair Whisperflo-24 1.0 hp.
Thanks in advance
Alexander Aymond Home Depot sells 2" and 1.5" fiitings. You can also order them online if needed.
what is the size of thatfitting extender on both ends?
where do you purpose those fittings? they look different than your house water pcv fittings. smooth all on the outside. not stepped.
zone Zone yeah the pool ones are schedule 40, but house plumbing is generally around schedule 20 I believe
thanks for the video
My pump is not holding water when it is turned off. The Does it mean I have a leak some where? What would be the best way to diagnose and repair?
It could be a number of things sounds like you need a check valve on the intake pipe of pump especially if the pump equipment sits higher than the pool water. If its higher i would put check valves on intake, skimmers and main drain..hope that helps.
Excellent
Quick question what happens if there's an air leak an I continue running pool pump ? likes before prior to you replacing both sides of the pool pump itself with pvc tubes . I seem to have the same problem where its beginning to leak I think cause it's an older pool pump.
+Omar Ruiz Nothing really short term. The air leak may just get larger and vacuuming the pool may be troublesome in some cases.
Where can you buy the fitting extender?
i have a pentair wistle flow that needs to be repaired , so my question is that do u have a video that show's you how to do that ? like my water pump could screw off from the top and where the water comes threw and i could pull it but i don't know how to take off that big grey wire thats on the side off it ?? any tips ?
take the back plate off Disconnect 3 wires - note how they are connected. Then unscrew grey connector. very easy to do.
how do u disconnect them three wires ...?
Chapo guzman once you remove the back plate (It is held on by two hex screws) you will see a simple wire set-up for the pump. The wires are held on my screws - just loosen them and you can pull the wires off. After wires are off of the motor you can unscrew the grey cord and remove the pump & motor.
what's that white stick called ??
What do you do if the threaded fitting was glued to pump housing?
Use a cutting tool like the Milwaukee M12 12 Volt Hackzall - cut into the threaded part making hash lines. Careful not to cut to the threads. Then use a rubber mallet and chip those pieces out with a rubber mallet.
@@SPL Thanks for the info. I have another question. I have a Super II pump assembly with a 2HP motor. It requires an impeller ring. When the ring is installed the pump rattles loudly. Take the ring out and all is quiet. What is the ring for and is it necessary to have it installed.
lol... Probably don't have to use QUITE so much glue if the pipe was cleaned and you turn the fittings as applying....
Small debris on a dirty pipe + gluing fitting straight on with no twist = leaks!
channel locks not wrench
Do you work on pools in NYC?
The pump manual states you must have 5x the diameter of the pipe before the intake before it hits any bends in the pipe. 2" pipe requires 10" of straight pipe before you hit a 90* before the intake
5:52 racoon sighting
😂
U shud use primer it cleanes the pvc and gives the glue a beter bond of u use hi presher
Did you ever have to repair a leak after this video. I see the home owner does not check the water level
Yes. I added a Pool Sentry on deck autofill to this account and good since.
Swimming Pool Tips, Reviews & How To - SPL nice. That is a good thing if the water level is always getting low and I am surprised the pump did not burn out yet
why don't you use a primer when you glue?
I do when it is getting inspected. My newer plumbing videos show me using it. The exact same ingredients in primer are in the PVC Cement... a plumber friend said it is a vast conspiracy to get a double sale. If you put the right amount of PVC Cement on you are fine. Lots of guys skip it.
thats disgusting! nice job but looks ugly, try using clear primer and clear cement.
Fernando Galvez ,,clear glue is the wrong glue for pools. Grey is strongest and best and resists the pools harmful chemicals
at least you didn't make a mess.....
Ha haha, you got me there ;)
PVC PIPES LAST FOR 100 YEARS I HAVE BEEN TOLD.
Would you tell that owner to keep their pool pump area clean wow crazy mess for no reason tell them to clean up the leaves.
Called "PLASTO JOINT STICK"
Nasty
Thanks for the vid
