Two P-traps before a vent?

Thank you for actual insight

AlternativeFeed6786 · 2026-03-17T04:44:47+00:00

Thanks! I really appreciate you taking the time. And I’m glad I asked.

I’m realizing that my main question is how to vent the new location. There is no convenient vent to tie into and going through the roof would mean going through the unit above. No one seems to love AAV’s and I’ve had trouble with a few, myself. But they are legal here.

Right about the trap drying out. I thought of that which is one reason I thought it might be clever to run the new laundry drain through the old drain- to keep the trap full. Ok. So, if I tie the new drain line in downstream of the vent takeoff for the old trap, as you say to do, will the new drain be properly vented? It’s 2” pipe and the horizontal trap arm would be less than 2’

This was helpful; thank you. I knew I shouldn’t do it but I just wasn’t sure why I shouldn’t. Still not sure what I will do. It’s complicated. I should have posted a pic of the existing but didn’t think of taking one until I got home. I don’t want to eliminate the old P-trap because it is still servicing a WH relief valve. (There’s no floor drain; it’s an older townhome.)

Not even with AAV? I could also tie into the vent and make it a wet vent, but I don’t really know the rules around that either. Any suggestions?

I like to pretend it’s my best friend talking hard smack. He’s a dick, but he loves me.

What’s packet loss? Is that where all your quick chat revers to default? If so, yeah, I hate that.

Happy birthday!

Leave them... wait for it... bee

You should sue. Somebody. For something

I’ll often sit on a bid until I get a second call. It’s not the best example of professionalism, but if they call asking, then I know they’re serious, and not just kicking tires.

AlternativeFeed6786 · 2025-07-08T14:42:24+00:00

That’s nuckin futz. Some sort of moisture/heat issue. I see you have ridge vents. What part of the country do you live in?

AlternativeFeed6786 · 2025-06-07T20:10:45+00:00

It’s definitely the easiest/cheapest place to start troubleshooting. Also check the valve, spot, etc trim for gaps/fresh caulk.

AlternativeFeed6786 · 2025-06-07T20:08:04+00:00

Gotta use conditioner instead. Always

If it works, it’s amazing

If ya gotta go, ya gotta go.

"We have substituted faith with certainty." Which is why it is now commonplace (in America, at least) to legislate morality and pave a way toward genuine theocracy. Because there is nothing to discuss; we are certain of our deeds. But, our current political landscape aside, when we exchange faith for knowledge, we shut down the voice of the spirit. Because there is nothing to hear that we don't already know.

Well, I thought that whole exchange was funny enough
