Installing washer supply box into wash tub


Okay I have a situation that is driving me nuts. I am finishing an area for my washer and dryer with a wash tub on the other side of a soon to be finished wall. I understand that it needs to be a 2" drain. But my problem is that I do not have access to a 2" drain to the floor it is 1 1/2". So that being said I have to drain into the wash tub, but can i use 2" in the finished wall and drain it into the wash tub it would be no more then 4 feet away. I am trying to have a finished look without cutting a hole in the wall and hang the wash machine hose on the tub. And if it is okay I wouldn't need to use a trap but still use a 18" standoff, correct? I want it to be right so if you say to hang it on the tub then I will. Also I am in Minnesota if that helps. Thank you so much for any help you can provide.

All below grade drains have to be at least 2"

Do you have access to a jack hammer?

And what does the washtub drain into?

You may be grandfathered in with the 1 1/2" pipe.If so... let it ride.
Well, at least until the old galvanized gives it up.

Re: Installing washer supply box into wash tub


No I don't have a jackhammer nor interested in looking I know it's 4 in out to the street. It is 1 1/2 going into the floor. It was built in 50 so yea at one time it was all galvanized. It's all been replaced with PVC. But again this is my best option available. I don't see how it would be any different then hanging the washing machine hose off the sink.

And it'll probably be just fine. Until it isn't.
But you're the one who raised the 2" pipe issue... right?

When the 50yo house was re-piped did they dig up the floor too?
I suspect you have 50 year old galvanized 1 1/2" pipe in the ground.
Ever seen the inside of a 50 year old galvanized pipe?
It ain't pretty LINK

does not mean that branch is 4"... what are 2 closest plumbing fixtures?


It is 1 1/2 going into the floor. It was built in 50 so yea at one time it was all galvanized. It's all been replaced with PVC.
if it was replaced then you should have at least 2" pipe under floor... what kind (& size) pipe rises out of floor, metal or PVC?

But again this is my best option available. I don't see how it would be any different then hanging the washing machine hose off the sink.

difference is draining into laundry tub allows capacity of tub to accept/store excess water pumped until/as drained by gravity. Teeing in an 1 1/2" connection for a washer drain, (especially if tied into an upstream 2" trap not only is not code but) could easily allow/cause an overflow of the washer stand pipe rather than excess water back flowing into the tub due to pumping action... & 1 1/2" trap/standpipe also increases your potential of an overflow out of standpipe due to utilizing an undersized drain.

IMO your best option could be to run an indirect drain (ridged piping protected from damage & secured/supported as extension of your washer discharge) from a washer location through the wall into the laundry tub; preferably exposed or as large as you can logically fit into the existing wall structure with fall/slope (minimum 1 1/4" - 1 1/2" that will accept the washer hose diameter). This could work only because both ends are open & all bends used are 45`fittings to make long sweep turns (no 90`short sweep turns) & because both ends are open to daylight.


Peace

Re: Installing washer supply box into wash tub


Thank you DR P that is exactly what I had in mind just wanted to make sure it was ok to do it that way. Do I still need a big standoff? The reason being it the tub is at 30 inches high plus a 18 inch stand off that puts me at 48 inches plus a 1 1/2 slope 49 1/2 inches. Which is fine. I know the washer hose will reach the box but would it be to high for the washer to push? They are on pedestals so they sit higher anyways.

Re: Installing washer supply box into wash tub


washer will definitely pump as high as hose will reach...
some much higher with extension.

as to standpipe ideally minimum 18" high but the
drain & water connections should always be readily
accessible & preferably visible for inspections IMO.
so with a pedestal involved a few inches higher should not matter

in this instance the ridged piping is simply a raceway
& permanent extension of washer discharge for directing
the pumped waste into a proper code approved receptor

as long as raceway is not obstructed & long sweep combination
fittings are used, that is the key for your setup IMO

Peace

Re: Installing washer supply box into wash tub


You also have the option of draining the washing machine into a laundry tub or standpipe.
