The CPC is the UPC with the California amendments added. You may have additional County and City amendments. Trailers and mobile homes are governed by the DMV in California so the CPC does not apply to them. Some Inspectors will allow an AAV but they are not really approved for general use.

I see them on outdoor location like a barbeque with sink on a Island. Thats What Im talking about, Its not legal but I would possibly do it dosent seem like a big deal. I figure if it works in Arizona It might work in California too!

winslow

with a foot vent, as stated in the UPC.

not legal here. fl code is based off icc

Sure Ive plumbed hundreds of Island sinks. But when someone is adding a little barbeque and sink I hate to have to run a vent over to a spot in the yard and then run a 10 foot stack up (looks like hell) or bust out a bunch of stucco to tie the vent in inside the house. Ive done it though, The code does seem a little restrictive and un nessesary though. What was someone talking about UPC flat venting, I Dont have a problem with other issues involving venting. I just think they should lighten up on special circumstances. As far as I know an inspector is breaking code to allow a studor vent under UPC. I dont know legaly if they have a right to allow it

i haven't seen the upc code for a while, but it used to be that if the code official approved it, an auto vent was permitted.

LISTEN!!!
I've heard everyone's concern, dislike, dismay, opinions, etc. & you all have very

good reasonings/answers BUT, "The once & for all true response to this delima of

AVV, Wet-Venting, Separate Venting IS"....

1st. = If & when the Engineer/Architect signs off on those approved plans with his seal (1) & the planning & zoning approve them then its out of your hands, the code book hands, because your code officials have officially signed off on the plans but making there Dept./City/State liable legally (which sets them up to be sued if not coorectly reviewed)

2nd = thats the only thing that matters isn't it if the code officials sign off on it??

In our juridiction Ive never seen a set of plans weather approved or otherwise calling for Studor vent Now your talking about something that has been Engineered and Approved by the building department. Dont know how that works. I had a gas line installed per plan under a patio cover and the inspector said after it was all done that this had to be fixed it was against code it needed to be sleeved and vented as per UPC code. It opened a whole can of worms but you say if its on the plans its all good? We got a letter from the gas co. stating it was ok and they let it slide It was a public elementary school.

oops i changed my mind

Does the IPC or UPC allow multi-storey wet-venting? (The National Plumbing code does )

Wet-venting a laundry tub/laundry machine with a kitchen sink\dishwasher on the floor above is now standard in the homes that we do.

Or wet-venting a bar sink (basement), with a kitchen sink/dishwasher (first floor) and two lavs (second floor). What a system!

I never seemed to understand the reason for soo many different plumbing codes all over the USA. Why not have one uniform code? (Except for Chigago, they don't seem as they will ever change lol)
