laudry room drain issue... please advice

lupe · Sep 17, 2007

I connected the drain as per pic, it was working just fine, until about 3 weeks ago. How its clogged up. It appears that its just clogs up when the washer machine is running and draining its water.

I ran a snake through the pipe and and ran presure water down the drain and the water flow is ok, it does not clog up.

Any suggestions ?

Thank You..

Suggestions for what?
I will say the horizontal connection after the P-trap should have been a tee-wye instead of a combo wye.
Your post appears to state "..the water flow is ok, it does not clog up", not sure what the question is.

The discharge from w/m is pretty forcful.Make the tee lower absorbe some
the shock. Santee?

they should print arrows on fittings to show which way is up. Which way it has to go (up, down, ) to be used right.

- San Tees get used the wrong way around, and that doesn't provide a nice long smooth sweep for big water.
- Combos get used the other way around, and make 3/4 "S" traps.

I haveused santees on stand pipes ane never had aproblem as long as the
stand pipe is long enough,4ftfrom center of tee to washer box.

Should have a santee instead of a combo.

The p-trap should not have such a big space between the two parts.

I would cut out the combo, use santee at a lower point, and make the standpipe longer.

Thanks for all feedback. I did some changes to the drain, however it still overflows slowly when the washer machine is draining its water. At first it sounds that water is flowing fine, then I can hear the standpipe getting filled until it start to overflow.

I've posted the first pic, then the second with the modified drain.

Please advice...

Thank You..

You have blockage or a bad connection/undersized drain below.
I recall seeing a cleanout near the base of the drain above the floor, good move.
Snake it there.
