Remember me? Making progress and delightfully impressed with how its coming although I have some more questions... 2" shower drain is approx. 2 1/2 to 3' run to horizontal stack...so I am assuming I do not need a vent? Also when I start the front stack the 3" toilet drain will be only a couple of feet to connect to the vertical stack... is a vent needed? Also what are the support/hanger requirements for waste pipes? Hmmm... when I tie the vents together in the attic to run to the rear of the house to exit the roof can I take the vents from a toilet, sink and tub connect them in the attic into 1 2" pipe and run them to the rear to connect to the other bathroom vents? What's your opinion on CPVC for water supply in homes? THanks a bunch...

Hi John... give me a minute to review old post and to put my thoughts together. Check back in 15 minutes.. ;)

Let's see John:

You said, " 2" shower drain is approx. 2 1/2 to 3' run to horizontal stack... so I am assuming I do not need a vent".
I ask...did you mean a VERTICAL vent stack...??

You said, " when I start from the front stack the 3" toilet drain will be only a couple of feet to connect to the vertical stack...is a vent needed?"
I say: How are you picking up the tub and lavatory waste lines? They must connect into these pipes somehow (you knew I wasn't going to make this easy... right... ;) ).

Support/hanger requirements:

Support waste stack at BASE of stack (using A Band hanger and threaded rod or similar.. pic. #2), and at every floor level (use riser clamp, see pic. #1! ). Otherwise, support all waste/vent piping every 4 feet, per code requirements.

Now, Can you take all those vents and connect them and run them as 2" pipe to vent... ANSWER... YES! Just make sure pipe is pitched back toward vent stack and is hung every 4 feet using clips (sorry, no pic.. but you get it... pitch pipe, slide 1/4" wood, then 1/2" wood , then 3/4" wood , etc. under pipe and clip down to keep sturdy.

Get back to me with info. I requested. Talk soon.. Mark

.

Well the vertical stack comes out of the floor, reduces to 3" and I turned it 90 degrees with a wye 1/8th bend to go horizontal along the foundation wall to pick up the bathroom sink, toilet, shower and kitchen sink. So the 2" shower drain can connect to that horizontal drain within 2-3 feet.

I was going to do the same on the front stack, 4" out of floor with dandy cleanout, i'll have a laundry tee for my washer coming off then reduce to 3" up the wall. I can connect the toilet into the vertical stack near the top where I plan to turn it horizontal 90 degrees to pick up the tub. Although I might be better off to run the 3" stack right up to the attic so i can drain the bath sink into the stack in the wall.

2" vent will work well then, I can connect the toilet, sink and tub from the front bath into a 2" and run it back and connect it to all the others. This will give me only one roof penetration.

I'll get some pictures might make more sense.
Thanks.

Hey John.

Pics would help for sure.

Sounds like you're on track here. Give us what you can, see what we can come up with. Thanks... Mark

Here are some photos of what I've done so far...
The first pic is the 4" stack reduced to 3" then transitioning to horizontal.
The second pic is the same... first drain is from the bath sink, second is the toilet and the third stub out that isn't completed is for the shower. At the end of the horizontal run is a cleanout and the wye you can see is going to go to the kitchen sink which will be located above that basement window.
Pic 3 you can see my sink drain toilet drain and vent,
Pic 4 shows the distance for my tile shower drain to the main drain.

Wow John:

You have done a real quality job there... hung almost as good as a pro could do it (code calls for hangers every 4 feet on PVC).

A little overkill on the cleanouts... but hey! Won't be needing any plumbers to unclog anything at your house... ;) Hey! You really have done a very nice job!

So that open 2" dandy cleanout is for the shower.. right? If so, will need 2" trap and 1.5" vent (put a dry piece of 2" with a jim cap over the end on that dandy cleanout and cap/plug any other open drain piping... especially if family around anywhere.. ;) ).

In terms of what to do at the front bathroom.. as painful as this is... I need more info... basic layout planned, direction of joist in relation to where the stack is coming upstairs... that kind of stuff..?

Let me know what you think.. Mark

I'm sure there will be more. Did you see the shower drain? Is that close enough to not worry about a vent? When I start the front stack I'll check back with you guys cuz' it's a little different.
Oh and what is your opinion about CPVC for supply lines?
And again thanks for the help you answered my questions that let me do the job I did. Thanks a bunch.

Hi John.. sorry I was revising my last post because I did not think you were online. Read my last post before this... post back with questions. I am here for awhile.

I was going to revise other post... but thinking that will only confuse... so...

CPVC is just fine for hot/cold water if acceptable by code in your area. Just be sure to connect copper to the water heater and to the boiler (if you have one) at least 18" off each unit and then transition to cpvc or PEX pipe (see below).

I am a bigger fan of the pex thermoplastic piping system. I use viega pex... just need a $200.00 tool kit and can be crimping water fittings together pretty quick... the labor and cost compared to copper is not even close. Google viega pex... get back to me with your thoughts on it (and then call local plumbing supply house and see if available in your area.. if not, may be that WIRSBRO is pex system in you area... also need tools here).

You're next unless you posted while I posted... I swear!!

Ok, so I will need a vent for that shower even though its within a couple of feet of my horizontal 3" drain?

You sure will John, If you just tie the trap in you will have built a "S" trap and that's a "code no-no". On another note I'm with Mark. You put in a professional looking job,( and that's just about the highest compliment that a plumber can give you. This is s first for me. I've never seen so many cleanouts on one job before, and I've been plumbing for over 50 years. That's not a bad thing, just a little unusual. But over all you put down one hellava job. Cheers, Tom

Thanks for the info and compliments... I'll keep pluggin' away.

How's this layout look for venting the 2" shower drain. The vertical stub off the wye will be the 1.5" vent will be sent up through the bottom wall plate with 90 degree elbows.
