I had to have my sewer pipe unclogged in 2017 and again last week. I don't use a garbage disposal and have hair traps everywhere but the discharge hose for the washing machine. I suspect that the cat hair and my hair going down this drain and catching on a rough spoti the cast iron sewer pipe is the culprit. The discharge hose drains into a pipe behind the washing machine, and that pipe connects to the pipe that drains the laundry sink. I can't think how to put a strainer on the end of the hose and be able to clean it easily. So I want to put the discharge hose into the laundry sink and use the sink strainer. If I do this, the hose would be at the same height as it is now. I would guess I would have to occasionally put water down the stand-alone pipe to keep the sewer gas from coming into the basement.

is it ok to do this, and if so, is there anything else I should consider before doing it?

 

Welcome to the forums.

You could put a cap on the drain stand pipe too.

 

Oh, good thought. Thanks!

 

Hi, I've had the same problem. I installed a deep sink to drain the washer. On the end of the hose I bought a lint strainer (it looks like a metal sock ) I attache it with a metal hose clamp. Works better than a nylon tie. The strainer catches the lint and that causes the water coming out of the hose to spray in different directions. To cure that problem ( water sprays everywhere ) I bought a 32 oz coffee creamer jug. I then cut the bottom and the top of the container and installed it over The strainer. That keeps the water in the sink. I then got a 1 1/2 inch tail piece make sure its about 1 or 2 inches shorter than the sink. I drilled a bunch of holes about 1/8 to make another strainer that fits the sink drain if the sink drain is larger than the tail piece put some tape around the bottom of the pipe..
Once a year I mix 3 gallons of water with 4 cups of sulfuric acid and I dump it in the sink drain, let it set for about 15 minutes then flush the line out for about 15 minutes. I haven't hired a plumber in about 6 years.

I too use those washer socks like Woodbutcher and replace them every 6-12 months (maybe they can be cleaned?)

But I'm more concerned with your clogs in your main drain. Lint or cat hair shouldn't be causing any kind of clog on their own. You may want to consider doing a camera snake down your main drain either now or the next time it clogs. There is probably either a dip or a collapsed pipe that's causing "soft waste", as some plumbers call it, like toilet paper, to get backed up.

Probably no rush to do it if everything is running well, but I wouldn't be surprised if you get another clog in a couple years regardless of how careful you are.
