    I am installing a bathtub.

    the drain is brass. The downpipe is brass.

    Two issues: 1. What do I use to connect the brass to PVC?

    Can I use a 22.5 fitting as on offset on the downpipe to avoid a joist?

    I really don't want to notch the joist. Actually I would use the 22 attach it to a straight pvc and then use another 22 at the opposite angle so the pvc would then go into the p-trap

    The copper-to-plastic fitting is just a regular slipnut, same as any other drain/trap connection.

    On the offset issue... I'll just mention that they're pretty common on sinks, so I don't see a problem. But I'm biased*, so you might want to wait for one of the plumbers to weigh in.

    I'm going to take a gander you mean an offset on the standpipe directly above the trap..if so it's ok as long as it's no greater than a 45.

    Frenchie...I also have 18 volt cordless sawzalls....muahahahaha

    thanks grump...

    it should be 22.5's ... i didn't think it would be a problem...it's not like it's s..t going down the drain...sorry for the language.

    this has been a challenge.... i am putting a tub where a shower was.... they had cut out a 36X36 HOLE.. and i had to re-joist it... so actually the plumbing issue is sort of minor compared to the rest of the infrastructure and wood rot.

    anyway... you guys are great..... i figure before all is said and done... the plumbers , electricians, tilers, and carpenters will have saved me at least 6k... no kidding.

    i feel like i should donate to a charity.. and probably will

    Wow. Maybe I'm getting jaded after too many years in NYC; but that's a really great thing you just said.
