Hello,

I'm moving things around for my wife to make room for a tub that she will be grooming dogs in. I have an existing 2" standpipe that I put in last year...I'd like to extend that to a total length of approx 10-11' from trap to stack. In this run I'd also like to tie in a basin and the new dog washing tub. My question is how would this best be done?

Below are two pictures of the current setup. For now I'll be running 2x4 braces from slab to joists to support the drain line until the basement gets finished when it will all be done for a final time. And I'll also ensure the usual 1/4" per foot slope and use all the appropriate tees. The washer and dryer will be moved to the right with the basin between them, the dog tub to the left of that.






Here's what I'm thinking...I'm particularly concerned with having the washer send suds up either one of the tubs as well as how high the vent line should be (it has to be above the waterline of both tubs and the top of the standpipe correct?) Please scrutinize this and make any suggestions. I'll try to reply to questions ASAP. Thanks a lot for your help.




Thanks!
Pete

Add some dimensions to the drawing---what you have drawn will work fine ,however one fewer vent will probably work,too.

It's not exact yet and probably won't be until I'm actually putting it in. The stack is 40" from bottom of trap to rim.

The first vent and basin drain will be probably within a foot from the 2" standpipe trap. Should I eliminate the right-most vent and just call the bottom 4-5" of the center vent a "wet vent"? I don't want to run into situations where I am having water spouting out of the standpipe because I happen to be draining the basin when the washer drains.

As for drain heights of the tub and basin...the tub bottom is only about 4" above the centerline of the drain...I'm going to have to raise that aren't I? I'm raisinf the basin already so that's no problem The floodline of the basin or tub won't exceed the standpipe height.

Sorry for the vague response Mike...

Your set up is fine---one extra vent will only cost you $3.00 or so in parts---I would rather to much than to little---you are good.---Mike----

Thanks for the fast responses! How about that dog wash tub? Is the bottom of the tub being that low compared to the drain line a problem you think? Would it be a safer bet to raise the whole tub by 6" or so?

I'd raise it ---more for saving your wifes back than the drainage---although the extra height would be a safety margin.
