Can someone verify whether the laundry box and the dryerbox positioning is acceptable for a stacking washer/dryer? Are there any issues with placing 45s on the venting to avoid the dryerbox? I am pretty sure it doesn't have to be 6" above the drain??

See photo. Thanks

Variation on This Theme

Okay, so the image makes sense, but I have a variation.

I have a 2x4 wall instead of 2x6. Also, my dryer vent needs to go down into the crawlspace (yes, then over and out). I want to avoid the washer box drain. My only plumbing vent is too far away, so I plan to use an AAV behind a grill.

Can I still do this arrangement? Surely it's been done before.

The only problem with the washer box behind a stacked unit is that the valves are almost impossible to access them without pulling the units out, and that can be time consuming, especially if you are dealing with a burst water hose.

This is going to cause a ongoing nightmare with the vent needing constant cleaning!

Why? it should work better than the air and lint having to go up, fighting gravity all the way.

I have read numerous places to avoid going up as best as you can. I think a short run and metal duct would contribute much better to a clean line. Every home in my edition exits from the crawlspace.

I think I can get enough space and clearance for the vent and the plumbing. Strangely, it is hard to find diagrams of pics for stacked W/D's online. One friend raised the issue, same as HJ, about accessing the shutoffs. However, once again, in every photo I've seen, the stacked W/D hides the supply and vent.

Can anyone provide "I've done this" documentation?
