More Plumbing Advice

[VincentVega]

Another recent thread was very helpful, maybe the expects can lend me some advice too.

I'm replacing/moving the main sewer line. It seems like there are many ways to accomplish this and my main goal is to not create more work down the road.

In the pic the white lines are new. New line goes through the foundation wall and needs to connect to the new white 3" line to the right and a similar to be installed line to the left.

What is the correct flitting for the vertical to horizontal transition? What's in place now is dry fit while I think about it. Should I use a wye with a wider/longer bend or is it ok as is?




Thanks for any advice

I'm not a plumber, but I did the rough lines in our house 33 years ago. Those joints look appropriate to me.
Just remember to keep your horizontal lengths a "half a bubble off level" in their slope to the drain.

I don't know the codes in MD but the santee on the end of the pipe coming through the foundation would be a code violation in California. It should be a "combination wye' or 'combo' as plumber would call it. It can be a single fitting or a wye with a street 45 on it.
The black ABS tee above it is also against code. Most municipalities base their code on the UPC so they're probably against code where you are too.

Thanks, good info. I have one of the middle piece you posted, I'll test fit that. I really like the first one, seems like a good options.

I agree on the ABS stuff, lots of 'what were they thinking?' in this place.

Just remember to keep your horizontal lengths a "half a bubble off level" in their slope to the drain.

I'm a complete noob and sprung for the fancy plumbers level. At this stage everything is 1/4"/foot or slighter more. Thanks!

Thanks for the advice

As shown, the San T shown is correct for horizontal to vertical but not vert to horizontal ( at the cleanout). MD should be a IPC state rather than UPC but neither allow flow to stop quickly when you change to a horizontal flow. Spherical solids (code term for crap) separate from liquids when dropped vertically.
A short or long sweep in that location is the way to go. Keep the san t's for horizontal to vertical

wow good advice in a plumbing thread for a change!! lol

Yes code calls for a wye with street 45

[dyount]

The black ABS piping is permitted for drainage both inside and outside of the building unless local code says otherwise. Problem is using the right glue to go between ABS and PVC

Dyount, FYI
code is not a "state" thing
Each and every county/jurisdiction adopts there own code
I operate in three MD counties which all follow the National Plumbing Code

Plumb,
Not necessarily true regarding code adoption. I work in PA and the entire state has adopted the ICC series including the IPC. 35 of 50 currently use the IPC.
MD has adopted state wide the IBC building code and NEC elec code as well.... seems plumbing is a bit of a free for all if it's county by county. I've never used the NPC myself but doubt there's much difference between it and either the IPC or UPC.
States and local folks have no business writing code..... Most are just ICC books with someone elses cover on it for feel good effect.

Great info, thank you very much.

Thanks again for the advice. I picked up 2 versions of this today, one is 4" on each end, the other is 4"' and 3" on the verical section. Whatever fits or does it matter either way?
