Sanitary Tee on Back in DWV

[plumbnut]

I have read that a san. tee must be installed with the main run in the vertical postion. I read this after I installed the 2" sanitary tees shown in the attached picture. If these are not right, what do I need to replace them with? Also, the washing machine stand pipe is causing me grief. I am doubtful about the dry fit arrangement shown in the picture. Thanks for any enlightenment the plumbing community can provide - Steven Harrison.

The washer needs a combo on the horizontal.

Then a vertical santee, with an arm for the p-trap
Above the vertical santee, a santee picking up the vent for the revent.

What you have is something like a funny illegal S trap

I take it you never did find a plumber out there in Cali....hopefully your remodel goes well with the customer.

Thanks for the answer and explanation Terry. That helps alot. Grumpy, I'm at the beach in Alabama - definitely not looking for any plumbers or anybody else in California.

Looks alot like another job a guy was looking around for a plumber on.
I tried to find him one, but couldn't.
As far as the setup on your pic, Terry's dead on, that trap needs a vent run right where it goes vertical, the Tee-wye needs to be a long sweep..a combo wye or a wye with a 45 into it.

Thanks for your advice Grumpyplumber. Looking at your picture, I gotta say, you look a lot like Walter Mathau.

You do not have a legal washer drain, and why are those other 3 lines connecting between the drain and the vent? If they are going to be drains then they are using the wrong fittings, and if not, then they are not needed.

Thanks for the comment HJ -

the other runs are revents for the washing machine and a utility sink (ell at right end will stub out to p-trap on the utility sink). I am new to plumbing and decided to try to vent all traps rather than rely on proximity to a main or secondary vent stack. Overkill I supose. Yes, the washing machine stand pipe is wrong and I intend to take Terry's advice and get it right. Will the extra vents hurt anything or are they merely redundant? Thanks again.

No just change the stand pipe S trap. Just cut the trap into the vent that seems to be for that trap anyways looks to be the one to the left of the S trap. Other than that looks ok.

IMHO a better way to pipe it would be as follows....

Thanks Patrick88 and Terry - I'll post a new pic once I redo it tomorrow.

Thanks Markts30,

That is a really nice set of graphics and it makes things real clear - the only question it brings up is the green arrow pointing to the "Y" and fitting - do I have the wrong one on the 3" drain/vent stack? Steven Harrison.

[markts30]

The green arrow marked "Y" is simply the Y in the X/Y/Z co-ordinate system of AutoCad..
It has nothing to do with the plumbing...
That fitting can be a SanTee, Combo or figure fitting, it makes no difference...
Your fitting there is fine...

Thanks for clearing up that little mystery - it just goes to show even a great illustration can be problematic to a novice such as myself.
