Condinsate? Still don't get cast over PVC in a situation like that.

Is that the washing machine drain line in the smaller PVC?

God bless the aav. Saving "plumbers" from having to put thought and planning into their work.

The pvc is existing. We installed the cast iron as all the horizontal piping was leaking. The 1inch pvc is a washing machine connection. As for the AAV. There is no existing vent through the roof or a place where I can connect to the stack with out opening walls. So for saving me planing it is not saving any planing it is 100% accepiable code. And it is installled properly. Your fantasy land of over selling for pointless items is a complete waste of time and money.

No worries. The handymen around here use them too. You can upsell them on cast iron but upselling a vented drainage system is just going too far I guess

AAV's are code out here. Now, new construction I'd much rather revent, but if someone wants to remodel their kitchen, and are getting bids from other plumbers, the one that wants to gut their walls adding extra drywall repair is going to loose no matter what.

I've never done new construction, honestly wouldn't like it, however I have done a few whole house guts before. In that situation we always revent.

I had the displeasure of servicing a high end Asian restaurant years ago. About every six months I would have to change 12 AAV's because the place smelled like sewer gas. Wasn't the floor drains or anything simple. Never did figure out what in the system was causing the failures.

Never seen a washer discharge run in PVC before.

It may be an optical illusion but, is that 3" kicked a little in the coupling? Could be shadows, but looks like it's not pitching as much as existing. Otherwise it looks good. If AAVs are code there, then unfortunately in a situation like this, probably have to use it to get job... Here, I still would have to have it above flood plain or 38" above floor... That's our code though . So many different codes , I try not to look for that, unless I think it poses a health risk.

Two years ago we did a restaurant, bar sink was on an AAV. Even though we had it the required height above flood, the health department wanted it higher per their code. No big deal, I just don't like how code can be met and another code supersedes another. Make code code, end of story.

I do agree about AAV's needing to be above flood, however I have seen sinks backed up well above them and they don't leak. Not to mention the make good clean outs allowing you to flush while cabling.

UPC requires a support with in 18" of a No HuB band. Over time your PVC/Cast Transition Bands will pull and sag.
