Adding Standpipe to existing Drain and Vent

[KingPEX]

Greetings,

So, I'm tired of the small laundry sink clogging when the washer discharges.

In the picture you can see the discharge hose on the right hanging over the sink.

I'd like to add a Stand Pipe. Can I add to the drain running to the left of the sink? The sink is trapped under it. The Vent is on the right (to the left of the sink). The washing machine is shoulder to shoulder with the sink.

Thanks!

You can add a stand pipe as long as it has its own trap

Want a cheap option?

Laundry stand-pipe and trap need to be 2". That copper drain doesn't look 2" to my eye.

What size is it? It looks bigger going into the floor. What size is that pipe?

Might have to find a different spot to run a drain to otherwise.

On the existing laundry tub, you could double-up on lint catching with a lint trap on the output of the WM drain line, as Sylvan suggested, plus a LintTrapper on the drain. This guards against something in the sink, such a cough drop wrapper or a sock, from clogging the drain hole.

The drain looks to be undersized and it does not use drainage fittings. If that is 2" coming through the floor things could be reconfigured for a standpipe. Otherwise you are better off with a lint filter and the sink.
