View Full Version : Slow utility/laundry sink

My laundry sink drain is very slow. When a large wash is done, it fills up to only an inch away from the top. I'm cheating a flood every time a wash is done.

I unscrewed the trap plug and all seemed fine. I've tried drain-0 at one point but that was useless. I tried plunging and all I can hear is water coming up and down in the vent pipe.

Here's a picture of the p-trap setup under the sink.

Here's a picture of the stack this goes in to. The bottom right is where the p-trap from the laundry sink ends up. The arrow shows the pipe I can hear water swooshing up and down when I try vigorously plunging.

And here's what I'm trying to avoid.

No other drain in the house causes any issues so that leaves me to think it's not the main vent on the roof causing this problem.. but who knows. Any advice would be really appreciated.

I had the same thing. You need to call a plumber and have that drain snaked.

probably years of lint build up somewhere in that drain?

Galvanized pipe could be all corroded inside and the opening could be quite small. A snake might ream it out, but replacement may be called for.

When it corrodes, it gets rough, and any lint would be caught, build up, and slow the drain way down.

would snaking a corroded pipe be a bad idea then?

It might clean it out, if it is really bad, it might break through. So, it would either fix it, or you'd have to replace it...hard to tell which without being there.

Would the snake get entered into that cleanout access point in the second picture?

Possibly but then again maybe not...

It depends on where the clog is...

You can snake all day long at a convenient location, but if you can't reach the clog from there you are doing nothing except waste time....

The wye coming out of the concrete is 2"
If you were to remove the 1.5" pipe and increase to 2" until you install a 2" x 1.5" x 1.5" Santee, it would help, after the lower section had been throughly snaked and cleaned out.
Or you can just give it a good snaking and see what happens.

Absolutely! Hopefully it reaches the person that needs to hear it...

Would it also be ideal to set up the washer so it drains directly into the pipe instead of the utility sink? Or for older homes does this not matter? I guess I'd like to have the laundry sink's basin filling up as a warning that it's clogged again.

1. Then it would probably overflow the drain pipe, and
2. The sink would still fill up.

Do what any logical person would do the FIRST time it filled up, and call a plumber. You can speculate all you want to, and spend days doing it, about whether it would work, or what problems you could have, but in the end the only thing that counts is that the water drains.

I'm calling a plumber to fix/snake the drain but I'm also asking if it's best at that time to have the washer set up so it drains into the pipe.

Careful with what that plumber tells you. The plumber that snaked my drains said I could have a 2 inch standpipe, leading to a 2 inch trap that fed into my 1.5 inch drain. I know that can't be right. 1.5 inch pipe must mean using a utility sink to discharge a washer.
