Adding utility sink for washer drain


The old drain line can't handle the washer drain flow. After cking replies to similar posts, adding a utility sink for the washer to drain into seems like the best way to go.

Attached picture of existing drain. Lots of room to the left for extending the clean out, trap, and standpipe.

Rectangle approximates sink location.

Looked at lots of images; I'm not sure the best way to adapt the sink into what I've got. Any suggestions appreciated.

Does not appear to be a vent. Can you take a photo further back.

Adding utility sink for washer drain


but if you insist on a sink, extend that line and use a wye and a 45 like fittings 3 and 10 below. Just imagine fittings 3 and 10 rolled 90 degrees so the end of the 45 is now going to accept your trap adaptor and the run of the wye is now the new cleanout.

In the setup below, above fitting #5 is all venting--meaning no other fixtures above are draining into the stack above fitting #5

Looks like a vent downstream of trap- it's disguised really well.
Why won't your line handle a washer? Appears to be a 2" line as it should be. Have you cleaned the line?
A trap arm for a laundry tray should be at 12" above finish floor- yours looks higher so it may make a sink connection difficult

ePlumber - No vent downstream; one part of the plan is to incorporate a Studor aav downstream. NOTE: One of the reasons for the sink IS vent issue. When weather gets better, a 1/4" snake and I will be trying to clear the vent on the roof. Had a (1.) camera snake up there last fall (didn't view obstruction); (2.) followed by 1/2" snake, but it (probably) wouldn't make a turn; (3.) tried a hose, then one attempt using a hose / bladder (was nervous using that - was told I might blow through "seals") (4.) installed air admittance (Studor) valves under kitchen and bathroom sinks; (5.) recently purchased two 1/4" snakes and a "flat ribbon" snake thinking I may have more luck trying to navigate / open the roof vent obstruction using smaller dia.

hammerlane - yeah, it's 2" in the picture; I posted 1/2 dozen pictures in an album. One of them shows the 2" connecting to the "old drain line."

I have an accessible clean out since then, but snaking it hasn't opened things up sufficiently. Had plumber snake same drain; marginally better drainage, but not regarding washer drain. Wash cycle sends suds up through the kitchen double sink above. (More "vent" info in reply above to ePlumber.)

Don't want to restrict the washer pump flow (read some suggesting that as a solution).

Sinks seemed least "bad" solution. Replacing the rest of the drain run out the street is what's called for; big $$ some day. But till then...


I'm going to draw (but not well) your direction above and post. Think I got the idea. Thanks.

Right you were/are. So, can I add a 2" trap (to the 2" line) after the sink, and not use the 1 1/2 trap under the sink? Is that OK to do?

If I add a 1 1/2" line into the 2" drain, it will cause the utility sink that's being added to be elevated 7" higher then its legs take it.

instead of using the 1 1/2" trap under the sink, is it ok to run a 1 1/2 over into the 2" drain, and install a 2" trap there for the sink?

Try snaking your main drain first.

OK. Not surprised. I wrote it a number of times trying to explain it; didn't do a good job. I'll try again.

You mentioned the 2" drain line might be too high in an earlier post

You were right; it is higher, quite a bit -- center of the 2" drain is 24" from the floor at the spot it should connect to the 1 1/2" for the sink.

So, I can...

1. Install the tail piece, trap, and trap arm which will require "raising" the sink to accommodate the height.

or (this was the question -- "is this ok to do?"

2. Install a 2" trap just downstream from the sink connection, and use IT as the sink trap, eliminating the 1 1/2" trap under the sink. This would save a lot of inches on raising the sink.

Attached picture is where I stopped.

Can you get a picture of all the piping there? Show the kit sink and where your washer line goes into the ground.

How far did you cable? did you get to the main line?
