Wet venting...


Hello,

Had a question about my existing plumbing, and a question about how I want to change it.

The picture below shows the existing (sorry about the bad "paint" drawing...). Some questions I had.

1. The tub is considered wet vented, correct?

2. Is the toilet considered wet vented? (provided it joins as I have shown, I have yet to tear up that piece of floor), even though it is so close to the stack?

3. I'm not yet sure of the question mark portion of pipe sizing, but I'm assuming it's 1 1/2".

So is this adequate as is? (Ontario code..) My other two questions are about what I would like to change.

4. I need to move the tub drain to the right about 4 feet. I'm assuming I can still wet vent, but I would like to move the connection point more to the right to meet distance to vent requirements, would that be ok?

5. The 1 1/4" seems inadequate for a wet vent? I'd like to up it to 1 1/2", not to mention provide better drainage for the sinks. If I do so, can I still leave the continuous vent portion as 1 1/4"?

Thoughts? Thanks and I appreciate any advice or help...

Charlie

Ok, finally am able to add it. I couldn't get a paint drawing that would attach! Anyhow, the drawing is crude, but hopefully conveys my questions.

"CharlieR"
Yeah a little bit "crude"!
Some distances for your pipe runs would help!
A wet vent on your shower (Plus, 2 sinks) should probably, be 2 inch -
for the drains.
Where the "question marks" are, to the drain for the toilet -
should probably be 2 inch.

Ya Until I get the rest of the floor open, it's the best I could do, I don't have many drawing programs!

So it's a tub (with a shower), which normally is 1 1/2" here, but are you still suggesting 2? If I make that part 2", could the continuous vent portion still be 1 1/4"?

I think code in Ontario, is a 1 1/2" drain can wet vent, provided no Water Closets are on it. I wasn't sure if the toilet counted as being vented by the wet vent or by the stack....

The 1 x 1/4 re-vent on the sinks is OK.
Not knowing how close to the main stack the toilet is -
and, where the drain for the sinks and tub is (In relation to the toilet) -
1 X 1/2 might be alright.
The distances play a factor - you might not know those until you open
the floor.
(Yeah, I lost my "X-Ray" vision, a long time ago - now it's SawZalls!)

Thank you so much rossfingal.

I will get what measurements I do have and roughly the ones I don't have. I won't be able to open the floor till Saturday morning. I think it will be fairly accurate though, I'll grab them tonight.
The toilet is less than 2 feet from the stack... I think I have some pictures on my computer of what I do have open thus far, that may help.

Ok, so here are a few pics of the open section, and the clsoed section, but you can see how close the toilet is to the stack...

Not the best pics for the topic... but you can see that the toilet is *much* closer to the stack than to the continuous vent of the sinks... here is a really bad pic of that, sorry about all the stuff in the way...

the sink drain and tub/shower drain in the pic above, join just under where the cut off is. They presumably connect to the toilet drain right before the stack, but I am not sure of that...

Wet venting...


So, I've attached some pictures of my in progress re-plumb. I had a few specific questions. I've already done one thing incorrectly I've realized.
There is also a somewhat crude drawing of my intentions.

1. Where the sink drains meet the tub/shower drain. I incorrectly used a San-Tee on it's side. I've learned that there needs to be a more gradual curve, and that a combo wye is correct? Is that correct? Also, if I can't find a combo wye, is a Wye, with a 45 attached the same thing?

2. The part where the tub shower does two 90 deg bends to go through a floor joist. I currently was going to use what I believe are short radius or short turn elbows, and I get the impression that there are long turn elbows that are correct to use? What is the correct fittings to use there.... ?

3. I have a double combo wye, (again, made with 45's on a double wye), where the two sinks connect, I believe that to be correct?

4. Where the drain goes down into the wall cavity (from horizontal to vertical), there is a short turn elbow. Is that ok, or should this be a long turn as well?

Thanks for any help. Also if you see anything else wrong...
Charlie

A pipe draining from the horizontal down into the vertical can be short turn fittings

A pipe draining from the vertical down into the horizontal must be long turn fittings.


Horizontal changes of direction must be made with wye fittings, combo fittings, or a wye/45* combo fitting or other fittings of equivalent sweep. (read : long sweep)

Hope this answers your question in regards to the fittings you need.

Alan,

Thank you very much!
Yes. One last one though. A 90 degree turn horizontal to horizontal. Long sweep elbow, correct?

Thank you again.

Charlie
