I’m adding a laundry room on the first level of my home. You video is exactly what I needed explaining the codes in detail along with a point-by-point narration. Great job!!
I appreciate your timely response, and it is 2". I must be missing something. Please explain why it would not handle the upstairs washer if it's handling the first floor washer and has for 30+ years.
This video gives an excellent summary of codes to keep in mind, which is very helpful for someone like me who is installing a box for the first time. Thanks!
Awesome video. My daughter has been battling the smell issue for a while now and has took it apart and cleaned everything inside the washer. I tried to tell her about this and this is the video i needed to send to her to see. Thanks
Great video, love the explanation. One thing I will add is that 3:33 is not true, this is not an S-trap. An S-trap is against code because there is no vent. What you have created is actually a crown vent, and it will not siphon itself empty. I believe these are against code because the water has a tendency to get up into the vent, causing it to clog over time.
If the sanitary tee is horizontal with AAV going up and it goes horizontal in the wall after that where it turns down, does the sanitary tee and P trap still create a crown vent?
@@ivani8511 Depends how close the tee is to the trap. After the vent, the pipe is allowed to go down since air can enter before the section of pipe where a slug of water could form and plug the pipe. A crown vent is created when the vent is too close to the trap; basically, as water leaves the trap, it is travelling upwards and tends to fill the pipe. As flow velocity increases, the water occupies less of the area of the pipe, and an air pocket forms on top of the water. If a tee is too close to the trap where the water is still filling the pipe, it's possible to introduce contaminants into the vent which will plug it over time. This may not apply in all areas, but I have heard that a vent must be at most 5 feet from the trap, and no less than twice the pipe diameter of the trap. I have also heard that anything below the flood level of the fixture using the drain must be plumbed as if it handled water, basically your AAV would have to have a 45-wye combo. But, I have seen many cases where this is not done and a sanitary tee is used instead. Again, likely that only some codes require that.
Thank you! Your video was very informative. I'll be installing one of these in the next two weeks. It will be in an existing home so I'll have to cut the existing sheetrock to be able to secure the box and observe how the drain runs. (The sheetrock is textured so I'll cut the "rock" down the middle of a stud and save the pieces to reinstall them),
Thank you very much for such a great, informative and detailed video. Would you please provide the code reference where it is permitted to use an AAV as a means of ventilation for the laundry stand pipe? I need to keep it for my records as I am going through this same remodeling now. Thank you in advance.
Excellent video. I am working against a finished wall with a drain pipe going in the wall horizontal. P trap and AAV are outside the wall. Much like kitchen sink. In opinion 2 if the AAV goes down with a horizontal sanitary tee, do I still have to leave 2x diameter between the P trap and sanitary tee as there is horizontal drain after the vent. Hope I explained it well .
I had a handyman "plumber" install a box along with hooking up kitchen sink, shower, vanity and toilet. When the washing machine empties on medium or large load, the toilet bubbles, water comes up from the drain into the shower basin and the sinks gurgle. Is there anyway I can send you pictures of what this guy did so you can tell me what the problem is? He said the plumbing is vented, but I have no pictures of that. Thanks.
Adding new to old.. The old pipes probably have some build up in them, causing a restriction. you didn't notice it before cause all the pipes had the build up. That is if it is truly vented. Have your drains cameraed and cleaned. Hydo-jetting with some degreaser will work the best.
Great information. I'm doing a remodel and need to replace the box. Is it code to glue the drain to the box? If so, I cut the drain pipe and use an extension/insert to get the drain back in the proper location?
Great video. Thank you. I need to install one in my basement how would i do the standpipe if i need to pump water up to main waste drain? It is about 6' up and runs along back wall.
Great conversation. I think you may of miss read that second code at 2:30 Where it states to revert back to P2706.2 Pertaining to stand pipes. In other words, the 18” to 42” rule still applies.
Excellent video with clear explanation of how all of this works. Question: If the stand pipe is vertical down to the larger drain exiting the house, how would you add a p-trap? Can you run the trap over into the next stud bay, and then using 2 90 deg elbows rout it back to the original stud bay and then down the drain? We have access to the attic so I could run the vent pipe up from the adjacent stud bay. We just bought a house in the country and have horrible sewer smell coming from the washing machine stand pipe.
how far down does the ribbed drain hose from the washing machine go down into the drain pipe? (just asking because I had a new machine installed by a big box store and have been getting sewer gases into the house lately. I never had that with an old machine that I had for 10 years). Thanks for a great video.
Man your video may have helped me with a problem we have had in our old house since we bought it! Our washer has always over flowed at the drain we constantly have to monitor it when washing! I know for a fact there is no vent tied into the drain so I would guess that is why it over flows?
We are hooking up our washer in a new home and in this home it is set up like at 7:26 where both holes are open. We have no idea which side to put our washer drain hose on. There are pipes on both sides. Is there anyway to tell which side to use?
My trick is to take a piece of 1/2 pex pipe (or something similar) stick it in the holes all the way to the bottom and blow on it. if it bubbles, you're in the "P" trap. That is the drain.
I really linked your presentation 👌🏻👌🏻 I really appreciate the tips to meet code, pls keep that way of doing videos, you know your stuff 😎😎 Do you happen to have another video with a sink tight together with the washer machine pipe ?
Thanks so much for the video. Quick question, the two ends of the pvc trap is different. One side has a sharper turn than the other. What end do I put the sandpipe in? Thanks for your time.
Thank you for this very informative video, I strive to keep everything tight and functional. Would you have the brand of the box and vent, having trouble finding the double drain set up with valves, hammer arresters. Found a few, but looking at pics they don’t seem to have enough room for the head of the vent. Thanks!
I have an IPS Du-All outlet box, and will be installing on an ABS DWV system. I cannot find info on how to plumb the Studor into the box. I am assuming that vent pipe for the Studor will be cemented into the box for the pressure test (like the standpipe). Once the pressure test is done, and I knockout the cap, I believe I need a spigot X FPT adapter, but it seems like the drain socket in the outlet box has a stop inside of it that is smaller diameter than the ID of the 2" drain pipe, which seems like it would make installing a spigot fitting impossible. IPS documentation not the greatest.
Okay thanks , the diagram in the instruction manual says using an aav is okay as long as you connect back to the drain line 20 pipe diameters from its horizontal point
I'm trying to relocate a washer and dryer upstairs for a customer and I have everything but the drain ran at the moment because I'm to far away from a vent. I'm not putting the pipes in the wall due to the customer not wanting the sheet rock cut into, but at 6:03 in the video you showed a vent coming back up from the tee. How far up from the tee do I have to be for the vent to work properly if I was running it straight up?
Great video. I learned a lot and I subscribed, thanks! I have framed out a second story laundry room which is basically a carbon copy of the laundry room just below on the first floor. My problem is that I have no way of running a separate drain line other than out the attic wall and down the outside of the house which I really do not want to do. So, my question is, irrespective of codes, can I tap into the vent line from the washer below with out a problem given that both washers would not be running at the same time? My only other option is to tap into the 3" or 4" vent from one of the downstairs bathrooms but it's at least 20 feet away. Please advise and thanks so much.
@@PlumbingSolutionsLLC Thank you for your prompt reply. I respect your opinion and you obvious experience. However, this drain has served the downstairs washer for 30+ years without any problems. Given that and the fact that both washers would never run at the same time, why would it not work? I have no reason to doubt what you say but I would appreciate an explanation. Please advise and thanks again.
We are installing Two Washers and Two Dryers, stackable, next to each other in new construction. Could you explain how drains would be installed? Using a single 2" drain to the right of the two outlet boxes. Thanks in Advance, JR
Both need to be trapped , just one lower than the other . Then two sanitary tee's stacked on top of each other at your drain , you will want to go to a 3 inch pipe as soon as possible, and make sure it is vented.
On the 90 coming from the standpipe p trap shouldn’t that be a long sweep.? I thought code wouldn’t allow a short sweep 90 for drains and only on vents.
They have my washer vented with a studer valve under my Kitchen sink. The wash always comes up into the sink a few inches. I'm thinking about adding another studer vent at the box. Do you think that would resolve my issues of it coming up into my sink?. My washer box doesn't have room for a studer vent. Is there a small box I can get to put the vent next to my washer box?
I'm draining it to the yard, not into the septic system. Do I still have to vent it and fallow the 24/18" code? The drain line will be about 6' from the P trap. Also can I use 1" 1/4 pipe, instead of 1" 1/2 ? Thank you!
I'm moving washer over 6 feet or so in the laundry room. The current setup has no ptrap. It is also located against an outside wall. Can I still drill two holes in the load bearing stud so I can do the vent option you mentioned? And if so, what are those metal deals called that are on the stud? Thank you.
At 4 mins in. Im going to argue this. Those fittings are made that the trap weir, when installed fitting to fitting, is at least 2 pipe diameters from the inlet of the vent.
You are correct, for any area following the UPC. 2019 UPC 804.1 Standpipe Receptors Plumbing fixtures or other receptors receiving the discharge of indirect waste pipes shall be approved for the use proposed and shall be of such shape and capacity as to prevent splashing or flooding and shall be located where they are readily accessible for inspection and cleaning. No standpipe receptor for a clothes washer shall extend more than 30 inches (762 mm), or not less than 18 inches (457 mm) above its trap. No trap for a clothes washer standpipe receptor shall be installed below the floor, but shall be roughed in not less than 6 inches (152 mm) and not more than 18 inches (457 mm) above the floor. Of course, local codes take precedence so always check with your inspector on what is allowed. Also, some areas do not follow the UPC. Anyone in California, unless your local jurisdiction has amended it, follow the 2019 UPC.
You said 20 inches is standar…but my question is 20 inches from the bottom box. To where…. To top to the trap center or where? Could you explains to me Im new….
So that it doesn't siphon out the trap seal. The water discharge from the washing is under pressure. Take a bucket of water and pour it down your toilet with full dumping. The water in the toilet trap(bowel) will be siphoned out after the bucket pour. Same principle.
Great Video! Thank you so much. Would you have a rough idea of about what it would cost me to pay someone to do this for me? How much would a plumber charge to install the box and hook up to existing drain and water connections? I know there's a lot of things to consider, but just a round about figure. Thanks
It depends on a lot. Like you location prices very. how much pipe is needed . are you going to cut sheet rock? now if you have hot and cold water lines and a drain pipe already there adding a box isn't bad . but if there isn't you have to get it there and that can cost you.
I’m adding a laundry room on the first level of my home. You video is exactly what I needed explaining the codes in detail along with a point-by-point narration. Great job!!

Not everything. I dont recall him mentioning how far off the floor the box should be.
Awesome video. My daughter has been battling the smell issue for a while now and has took it apart and cleaned everything inside the washer. I tried to tell her about this and this is the video i needed to send to her to see. Thanks
Thanks for being direct and to the point. Very easy to understand the way you present.
Thanks for showing the stud shoes. I wasn't sure how to support a 2x4 with a 2" drain pipe going through it.
Great presentation! Well explained. Favorite line: "you start gettin' stink and stuff up in your house".
Great video. Really like how you explained everything in detail. Best explanation on RUclips!
Good job! Your information about the minimum distance between the trap and the standpipe is missing in most videos that I have seen.
Best presentation on this topic I've seen. Thanks!
Thank you keifer Sutherland for this great video. Easy to follow along when its time to do mine. 👍🏽
lol ... thanks
Great job!!! Exactly the help I was looking for because I'm getting ready to install one with a Studor vent. Thank you!!!
Great side notes, but still on track with everything leading up to the main topic. Enjoyed , liked, and subscribed!
Nice clear explanation. Wasn’t quite sure how to vent the box so I appreciate the help.

it just says above the drain

the trap and standpipe will be the same. then you'll drop that into your pump.
Now I learned how to vent my washer/garage combo. Thank you!
I did the second option, and did the EXACT set up just in 1½ inch pex (I'm in a 70ft trailer)... You saved me... Thank you 😎🙏
Great conversation. I think you may of miss read that second code at 2:30 Where it states to revert back to P2706.2
Pertaining to stand pipes. In other words, the 18” to 42” rule still applies.
codes are weird, a "P" trap can't be more then 24" from the drain. so I'm not sure who cancels who out. I just set it at 20" and I'm fine .
Thanks brother. I’m a carpenter trying to plumb mom’s house. 😅

Same issue I just dealt with. Have it all installed except the vent won’t fit in the box. 2” pipe won’t fit in the top.
Can you use an AAV on a laundry pump system? Moved laundry to basement and venting the pump thru the roof is a lot.
No, it needs to breath both ways. studer makes a charcoal vent that you could use .
Okay thanks , the diagram in the instruction manual says using an aav is okay as long as you connect back to the drain line 20 pipe diameters from its horizontal point
Excellent video. Thanks for the info!
Great great video! Best and detailed video I seen in a long time, you got a new sub!
Excellent Video. Very well explained.
Does the Air admittance valve need to be at least as high as the drain opening?
In other words, i have a studdar vent below the sink...Thank You!!
I’m wanting to move mine to another room and this really helped a lot. Why did you decide against Pex A?
Cost
Another question... can this be installed in current construction. Installing a washing machine into a laundry room without a drain.
Great informative video. How long can the run between the p trap and the sanitary tee be?
Has to be at least 2X the diameter of the pipe. here it's 2" pipe, so the length is at least 4"
I'm trying to relocate a washer and dryer upstairs for a customer and I have everything but the drain ran at the moment because I'm to far away from a vent.

If you're going use an AAV it has to be above the rim of the standpipe. (the drain pipe)

No raise your vent under the sink to about the rim top then throw on your studer
What a great explanation! Thank you.
Glad it was helpful!
I'm draining it to the yard, not into the septic system. Do I still have to vent it and fallow the 24/18" code? The drain line will be about 6' from the P trap. Also can I use 1" 1/4 pipe, instead of 1" 1/2 ? Thank you!

?
Love your vids! Thank you!
That stand pipe is 20 inches? Are you sure?
is there any difference in plumbing if i stack washing and dryer machines or is it the same? small laundry room
No, same set up
@@PlumbingSolutionsLLC thanks. is the plumbing always behind the machined?
if I wanted to add a laundry sink, how should I tie into the first set up (w/stack vent going up to the roof)?
Add a sanitary Tee to the standpipe above the P trap
Maybe you could help...Can I U turn the horizontal pipe coming out of the P trap ?
You mean like a sideways S or ~ . Old houses had S traps , we are not allowed to use them anymore. But old hardware stores still have them.
@@PlumbingSolutionsLLC thank you for replying, but I just redid everything, exactly like you showed
reading those quotes from codes it looks like maximum standpipe for a washing machine does not follow the 24 inch limit it goes 18 to 42
I thought that the 24” code for a trap does not a apply to a washer box, instead is from 18-30 inches stand pipe
You are correct, for any area following the UPC. 2019 UPC 804.1 Standpipe Receptors
Plumbing fixtures or other receptors receiving the discharge of indirect waste pipes shall be approved for the use proposed and shall be of such shape and capacity as to prevent splashing or flooding and shall be located where they are readily accessible for inspection and cleaning. No standpipe receptor for a clothes washer shall extend more than 30 inches (762 mm), or not less than 18 inches (457 mm) above its trap. No trap for a clothes washer standpipe receptor shall be installed below the floor, but shall be roughed in not less than 6 inches (152 mm) and not more than 18 inches (457 mm) above the floor.
Of course, local codes take precedence so always check with your inspector on what is allowed. Also, some areas do not follow the UPC. Anyone in California, unless your local jurisdiction has amended it, follow the 2019 UPC.
Your videos are so helpful!
Very Helpful! Thank you
You said 20 inches is standar…but my question is 20 inches from the bottom box. To where…. To top to the trap center or where? Could you explains to me Im new….
It's the length of pipe before you glue it in. so bottom of the box to the hub on the P trap
When you break a vent below the flood rim you are required to use drainage fittings. The washing machine stand pipe allowance is 18"-30".
Why does it matter how long the stand is? , does the water try to come back up the pipe?
So that it doesn't siphon out the trap seal. The water discharge from the washing is under pressure. Take a bucket of water and pour it down your toilet with full dumping. The water in the toilet trap(bowel) will be siphoned out after the bucket pour. Same principle.
Great Video! Thank you so much. Would you have a rough idea of about what it would cost me to pay someone to do this for me? How much would a plumber charge to install the box and hook up to existing drain and water connections? I know there's a lot of things to consider, but just a round about figure. Thanks
It depends on a lot. Like you location prices very. how much pipe is needed . are you going to cut sheet rock?
now if you have hot and cold water lines and a drain pipe already there adding a box isn't bad . but if there isn't you have to get it there and that can cost you.
Where can i buy that plumbing code book? And what is the name thanks? Great video
the book is expensive. you can get a free PDF on line. but mine came form Technical Training Institute
Can a stand pipe go diagonal? Say at a 45° pitch?
