I would like to drain my clothes washer into an existing standpipe rather than into the utility sink. I'm tired of all the lint clogging the sink and want to drain directly into the main sewer. I'm looking for a nice, clean, good looking, safe solution that will properly eliminate the drain water, guard against clogging, not allow sewer gases to return, etc. I've seen nicely curved connectors for washer drain pipes. I've also seen nice "caps" to seal the connection on the standpipe. I will drain this into a 4" diameter pipe. There is currently a cap on it. I would remove that and replace with a nice solution I'm looking for. I'm looking for suggestions and pictures of possible solutions.
Thanks
Steve

Hi Steve,

It sounds liike this 4" diameter pipe is a main sewer cleanout and as such can not be used as a drain without first running a vent. To accomplish this would result in a unvented "S" trap. Outlawed in all 50 states and Canada. Unless you can come up with another idea it looks like you're still using the utility sink. Why not tie a old sock over the hose to trap the lint. Regards, Tom

This is a 1940s house. This 4" pipe is connected to the main cleanout. This particular portion of the pipe provides drainage for a master bath shower and sink (don't know about the toilet) that was added on in the 1980s. Since it is for the bathroom, I believe it's vented already. This portion of the pipe is vertical against the wall leading from the second floor to under the basement. The cap is at about the 4 foot level. The main trap is another 20' away under the basement before the line exits the house. Since this is an old house, there is an additional vent that exits the house at this main trap.

I use a metal mesh filter on the drain pipe now. But it is annoying and gets filled up with lint very quickly. I would like to circumvent this. I think I would like something similar to the following link.

Nice try but no cigar! While your bath room may be vented the washer installation wouldn't be. This would be discharging a major fixture pas a unvented minor one and that's against code also. Regards, Tom

Can you explain how others implement a washer install without using the utility sink as a drain? Can you provide pictures? A web site for info? Product web sites?
Thanks

Here's a rough drawing on a washer installation. The vent can not have anything draining down from above, however it may go up and revent back into a existing vent at least 6" over the fixtures floor rim that it's venting.
Good luck, Tom
