#SNAPPY TRAP DOUBLE SINK INSTALLATION MANUAL CODE#

The hoses have a little bit of flex, but not much. I had to add a few parts to get it to work correctly.

#SNAPPY TRAP DOUBLE SINK INSTALLATION MANUAL CODE#

Of course, I know nothing about code up in the frozen tundra, so maybe not for you.I used this kit to plumb a laundry room sink. Pittsburgh has been requiring this arrangement for some time now, as they say its better venting - maybe they're just crazy, but I could see how it could theoretically be a better venting situation. I actually wouldn't be surprised if you start to see things like this creeping into the code, but who knows how long that will be. I'm not sure in my neighbor's case, but they went to good lengths to vent everything else, so there must have been a good reason.

It was literally impossible w/o completely changing the design of the house or creating a structural nightmare. I have the exact same situation, in that I was able to hard vent everything in my house while I had it gutted, but I have an exposed brick wall as my kitchen backsplash, so there was no way to feasibly route a vent line, other than to do an island loop, which I'm not too keen on either. These houses are 3 stories, so the attic is either non-existent (flat roofs), or 2 stories up. The whole house is gutted, and they've hard vented the laundry rooms, all the baths, etc, just not this kitchen sink. I don't know in his case, I didn't trace it down to see why they couldn't vent it. Only wye is where i split the 2' riser into two 1.5' lines, there shouldn't be any problem with that, right? The red dots in the sketch are AAVs, the yellow dot a 2' cleanout, the blue lines P-traps, and of course santees to tie in. So, whether or not you would do it personally, is there any code/safety/practical (other than extra work and materials) reason to not do what I've drawn below, to meet his requirements? I'm not a huge fan of AAVs myself - prefer to do real venting when possible, so maybe having 2 of them will help increase their effectiveness? Especially when the D/W, sink, and disposal are all dumping into the drain line at the same time? Or potentially reduce the chance of a clog if one of them fails? I can definitely see how my first design would fail now - thanks for showing me that those are indeed S-traps - but that doesn't change the fact that my inspector will probably fail me if I don't do 2 AAVs. This either is or is not one of them, but my inspector specifically said I can't do a sanitary cross with an AAV above it b/c I had to have 2 AAVs. I'm not trying to make it more complicated, but Pittsburgh is known for adding ridiculous extra rules to the code.

I would love to do a standard, conventional hookup - really I would. Sorry my town is crazy and likes to complicate things. is the cleanout required/necessary since you could run down through the AAV, or is it more of a convenience thing (lower, easier to get to)? I've got no problem adding that, might as well do things the best way possible while I'm tearing it apart, just curious about code requirements. So, do I split the drain and treat it as 2 separate drain lines coming up, each serving one bowl of the sink, as if they were 2 separate single bowl sinks? Is there any other way to get 2 AAVs in there? One last question. I don't like to argue with inspectors, I tend to find that it makes my life more difficult. I would normally do what Terry has posted with either an AAV or preferably a vent, but he wants 2 AAVs. So, none of the pictures/descriptions above work to meet that requirement. Not sure if that applies all the time, or just in the AAV case, or just b/c the inspector felt like it in this case, but thats what he wants. When he said I could do the AAV, he said that a sanitary cross (i meant to say cross in first post, not double wye) with an AAV above it is not legal here, and that I had to have separate AAVs for each bowl. The inspector was fairly gracious (didn't have to fight for it, he just let me do it) in allowing me to use AAVs in this case, but made me put in a vent in another location where venting was fairly difficult, but more feasible. Many of the city people should be asking if you want fries with that. Wally - haha, I dunno if its him or the city on this, but I know the city is nuts about a lot of things. Rich, I came across that website actually as I was trying to find information about this, but as this requirement is either odd to Pittsburgh or to my specific inspector, there doesn't seem to be anything about what I'm being asked to do. Thank you for helping me there Terry, I researched it more after you told me that. I was previously unaware that you could create one over that distance, but understand that concept now. I understand now how my first picture creates an S-trap.
