I have to turn my shower drain 180* in order to meet the new 3" pipe I am installing. I read a few places that after 135* a cleanout must be installed. Does this mean the clean out must be installed after the 135* of bends or as my photo below, between the trap and the begining of the bends?

Just so you know, I need to reroute the shower drain because the way it was hooked up before brought the floor up 2-1/4". The subfloor was all rotted and moldy.

No comments anyone?

How about ABS underground? Our local box stores only sell mainly 3 and 4" fittings in PVC. They don't even have a closet flange in PVC leaving only the proper assortment of fittings available in ABS.

Should I use the ABS to mock up and then pick up the same parts in PVC from the plumbing supply house after I know exactly what I need?

Thanks,

That's a nasty junction----Is it save to assume that you have no alternative?

You need a vent withing 5 feet of the P-trap----I'm not familiar with a code requirement for a cleanout--but it seems like a good plan----could you kill two birds with one stone and vent the cleanout?

My area uses PVC only--so I'll have to leave this one for a plumber with more knowledge---we have a good plumbing crew here--someone will have the answer for you--------Mike----------

Thanks Mike.

Yes, no choice. I had to take out the sub floor. It bugs me to see such shoddy work.

I should have shown another pic of the vent line. It is the 2" line that you can see below where the old shower connection was. It's a wet vent from the vanity, so the vent is basically a foot away from where this enters and this shower run is no more than 30" from the shower trap.

As you know--we have plenty of really good plumbers here----One of them will jump in---must have been a busy night in the plumber world last night-----

Odd that one of them didn't comment already-----I'd wait a little bit and see if one checks in----Mike---

I don't know what your elevation is in that ditch below concrete or how much you need. The cleanout rule applies only to horizontal change of direction.


Assuming your mainline is 4", you would use a 4x2 wye with a 2" street 1/8 bend in it or a 4x2 combo (wye with 1/8 bend might be tighter). When you install the 4x2 wye or combo, install it on a 45 degree angle. That is still considered vertical (no cleanout required for vertical change of direction). Now into the street 1/8 bend (depending on how much room you have) install a 2" 1/4 bend (you can use a street if you need the space but be careful, because now everything is so tight you would have to throw the entire fitting away if you screw up) and use a level on it when you glue it. Now you have gone from horizontal, to vertical, and back to horizontal again. No horizontal change of direction = no cleanout required by code. (mine anyway)

Hope this makes sense.

Don't mix abs with pvc- use one or the other. Might check with you authorities about their preference.
If that wet vent is copper- kinda looks like it- consider replacing it too while you're in there. Recycle it to pay for new parts

I was planning to use 3" for the main horizontal run with an MJ coupling to the 4" clay pipe. I need the elbow for the WC, a wye for the vent and the wye for the shower. 4" fittings would take alot of the length available. With the 3", there will be about 1-1/2'' between each fitting.

Is the short run of 3" to 4" OK?

So what you're saying is if I have enough drop, I'm actually changing to a vertical rather than a horizontal turn. Also, to use street elbows to my advantage.


Also, is there something actually wrong with the way I designed the clean out system? I'd rather not install it, but I'm always curious and like to learn more.

Thanks again,

I would never mix the two. I can use the ABS for mock up and then replace everything with PVC once I know which fittings I need. This includes the pipe of coarse.

A few more pics.

The 1/2'' pipe in the ground is the center of the shower drain. The piece of wood shows future location of WC drain and vent connection.

I have about 8" from the floor to the top of the existing 3" horizontal pipe.
If using the elbows in an almost vertical route, I can go almost straight run to it as shown in the next 2 pics. I know it needs a trap. I'm just mocking it up for a pic. Is this what you were getting at Alan?

Thanks,

I had the drains scoped with a camera yesterday. Everything looks great. A few tiny, stringy roots close to the property line. One small offset fracture about 1/2'' but it's going in the right direction. It steps down.

So now I'm going ahead and getting the ABS parts ready.

I've got the major turn all on a vertical drop and as I understand it, a cleanout is required on a bend more than 135* on a horizontal run.

The wet vent is entering on the side of the 3" horizontal. Is this OK or should I cut the 2" copper at the wall to bring it higher so the wet vent enters on the top half of the horizontal?

Thanks,

I don't really know how venting works where you are, but our drains are supposed to hit walls and each line have it's own vent taken vertically off the top of the drain.

So I can't really answer your question.

I'm going to proceed.
It was working fine before I tore it apart, no gurgling sounds or traps sucked dry. I'm basically putting it back the way it was except for moving the shower drain a bit to get rid of the subfloor.

Thanks again,
