You're saying between the two San-Ts picking up each branch drain(fitting #1 and #2) there should be 5'(5 feet) of separation?

Wouldn't that put the laundry sink at or close to the ceiling???

I think when we were using the UPC with oregon amendments, that was one of the blue pages (amendments) and we only need to worry about suds relief on buildings greater than 3 stories or something like that.

I've never had anyone complain about suds backing up into their sink, but then again, we have harder water here than most places. No need really for that nonsense.

Read this thread:
Running plumbing for utility sink

plummen · 01-26-2012, 11:33 PM

Thats why i say the washer is supposed to run independently to a 3" line with nothing else tied into it,around here anyway.
I cant tell from the picture if the stack is 3" or not,but lets just say its 2" to make it easy.
I would have run the washer drain under the floor to a wye cut into the nearest 3-4" line then by the time it got back to the sink tie in you would have over 5' between the 2 fittings and it wouldnt be an issue.
I got nailed in omaha years ago on a floor drain being roughed in less than 5' from where the wye for the washer tied in to the main,I never did it again after that.

We had a guy who thought he would put a bap adapter on the stand pipe right above the p trap then run pex from it to gravity feed a floor drain as a primer. The home owner called and said she had suds coming out the F.D.

I looked up the article in the 2010 city of omaha plumbing code .
Article 49-605b says washer must run independently to a 3" line and must be plumbed a minimum of 5' from nearest tie in to a wc,which depending on your inspector whos neighborhood you happen to be working in can be interpreted as basically any opening in a pipe.
It also says an existing 2" pipe can be used on a remodel if the chief inspector oks it,which basically means if either of his kids (who both own plumbing shops in omaha) need to use an existing pipe its ok the rest of us are just screwed!

OK Plummen I think I see where you're coming from...so you're saying the reasoning for the separation is for "suds pressure zones"

plummen · 01-27-2012, 12:13 AM

Yes ,thats the reasoning they use around omaha anyway.
Around louisville on the other hand you usually have to check the inspectors pulse to make sure hes breathing!

Hey I just realized its been over 24 hrs since ive been called a hack and had anybody want to toss me off the site,what gives here?
