Clean out cover would have been my guess also. Is it directly below where the drain is?

If that's a clean out cover, I want one.

It would appear to be a clean out cover?

and it's about 12 (that's approx 30.5cm for our Canadian brethren above lol) to the right of where the drain is.







Don't be offended I lived in Calgary for a few years so I'm almost part Canuck

We only use metric when we have to. I would open the wall around the clean out so the plumbers can give instuctions.

So here is what we've learned



Oh and there has been a change of plans.

My wife told me I wanted the sink in the laundry room in the corner shown instead of in the garage so I just have to get to the corner with the sink now instead of through a wall. Funny how being married changes things. lol

I assume 2" drain all the way into the slab?
Can't see it in the picture...

ME87

Yes on the drain.

So at this point it looks pretty straight forward to T into the PEX line, but I'm not sure about the drain and the vent, or even if a vent is necessary.

A vent is always necessary.

At this point you should check your locally used plumbing code to make sure that a 2nd fixture can be added on a 2" washer drain.

Are you looking at adding the sink to the right or, left of the washer?

ME87

Unfortunately, I'm looking to add it to the left, which I believe is going to make it harder.
