Does this adhere to the code? Washer/Drain/Vent


Hi DIY Chatroom Fellow Memebers,

I had a licensed plumber to move my washer & dryer to the other corner of the basement last week, so they are right by the stairs now. When my neighbour came in for a visit, he kindly reminded me to have the work double checked - especially the venting.

My neighbour admits that he is not a plumbing specialist but he is not sure everything he sees is all right. I am a newbie to home renovation in general, thus thinking to post the question here.

I have two photos attached. Can you see whether this complies to the building code, especially the venting? I am from Ontario, Canada.

Thanks in advance,
GT

The thick pipe on the right handside is the waste line connecting to the bathroom on the 2nd floor ... I am not sure where the vent is but probably there is one on the roof?

I can't see all the plumbing to the washer and sink, but what I think I see is a vertical offset in the trap arm- right by the vent. It is also piped in 1.5"? Both of these are code violations in my area. Should be 2" pipe and no vertical offsets between trap and vent. Oh, and is that a cap on the "vent"? Should at least be an auto air vent.
Let's see what some of our Canadian friends say...

Thanks for Eplumber's initial assessment.

>> Oh, and is that a cap on the "vent"? Should at least be an auto air vent.
- Yes, it is a cap. The plumber did mention that I could use some kind of vent too ... probably that is the auto air vent you are referring. Is that also known as the Air Admittance Valve or Cheater Vent? My question is: if I change the cap to the air vent or AAV, would that be good enough; or the vent should go outside the house?

>> ... It is also piped in 1.5"? Both of these are code violations in my area. Should be 2" pipe and no vertical offsets between trap and vent.
- Yes, it is 1.5". So instead of vertical, your code requires the pipe to go down with a slope? There is a water meter so the pipe has to be lowered somehow ...

>> can't see all the plumbing to the washer and sink ...
- I will post another picture once I get home tonight.

Thanks,
GT

Hi there,

Here's an illustration of what an install should look like,

E-Plumber is right, 2" pipe for the drain and the offset on the horizontal is a no-no. AAV (air admittance vent/cheater vent) should be alright, but check with your municipality to be certain. Out of curiosity why did the 'plumber' put a cap on that vent and not put an AAV on? Or why even bother putting that whole drain system together when there's a perfectly usable, and legal, laundry tub right next to the washer?

call the plumber back and ask him to look closely at his install......then ask him to do it right... not a good install here either..

Thanks for the opinions from VIPlumber and Ben.

Now I have the 3rd photo for the drain under the laundry tub in the original post.

----------------------------

VIPlumber >> Out of curiosity why did the 'plumber' put a cap on that vent and not put an AAV on?

- First, thanks for the illustration. Question: does this mean that the vent besides the waste stack is not necessary?

- Here is what plumber said originally about the vent: if the drain/trap under the laundary tub is clogged, you can put the washer drain hose in the pipe (vent) while you are cleaning the drain/trap. Thus put a cap there without glue. Or you have an option to put an air admittance vent. BTW, the deal was that I would buy most of the materials and pay him for the labour. Thus I bought a cap to put it on later myself.

VIPlumber >> Or why even bother putting that whole drain system together when there's a perfectly usable, and legal, laundry tub right next to the washer?

- Do you mean that I could just put the washer drain hose in the laundry tub? The whole system (drain system plus the laundry tub) actually was there built ready by the builder when I moved in 4 years ago (bought new house). Now the work is just to move it to another place so not much new build I guess ...

VIPlumber >> E-Plumber is right, 2" pipe for the drain and the offset on the horizontal is a no-no.

- I think the builder used 1.5" for the washer drain orginally and it was just moved over. Anyway, it seems that needs to fixed.

- I also checked other drains and found the drain for the powder room is 2". The drain for the kitchen sink is 1.5" ... is this a violation as well?

Ben >> call the plumber back and ask him to look closely at his install......then ask him to do it right...

- I called him and he will be back mid next week. I will keep you guys posted.

Thanks again everyone.

Your powder room sink may be using a toilet vent as it's drain in which case it would be a 2" drain. My local code also requires 2" for kitchen sinks. . .
