Hi TerryLove Forums Community,

I'm tasked with piping a drain line for a relocated washing machine within our 3rd floor bathroom renovation. The house is from the 1880's so the floor joists are 2x6's (nominal). The desired location for the new washing machine is located within the 2nd third of the floor joists.

Plan A: Run my pipe parallel with the joists until I hit the exterior wall, where I would then notch/bore through 4 existing joists to reach the existing stack-pipe. It's to my understanding that I'll need to be drilling +/-2 1/4" holes in the existing joists in order to accommodate 2" PVC drain pipe. Is this even possible given the rules on notching/boring through joists?

Plan B: I think is to path my 2" drain line through a wet-wall that will allow me to reach the joist bay the existing stack-pipe is located in.. but this will require having four 90-degree turns. Will that be too many turns, which would potentially be harder to unclog in the future?

Any advice you can give will be greatly appreciated. Thanks,

Zachary

I think you should clarify by clicking Edit. Your second sentence was the first confusing thing.

I think 2x6 floor joists are not normal today, but with old wood may have been strong enough. But I would certainly avoid cutting holes in those. I am not a pro.

Understood. I was just giving context of the situation. I'm not sure how to make it any more clear. Apologies for the confusion.

Ooops. I meant the third sentence was confusing: "The desired location for the new washing machine is located within the 2nd third of the floor joists. "

2 inch Long sweeps 4 of them clean outs or not I'd do that before hacking into the joists on my house in the center 3rd of span
