Studor Trap-Vent(in one)

[Coolwhip]

I'm asking about this product specifically https://www.ipscorp.com/pdf/studor/STU021_TrapVent_web.pdf

Does anyone have experience with it? When I first started looking at air admittance valves, I wanted to be sure to get ones that would never(hopefully) fail. So just wanted to know what you guys think about this product. I guess it has the advantage that it will probably be a little more accessible than where an independent AAV would end up...but I'd like to hear from some pros that they approve of it and haven't had problems with it if they've used it.

1) I have never used one.

2) Everything mechanical fails.

3) It looks like it would be easy to replace if it is still available when failure occurs. Is there an obvious plan "B" if it has been discontinued when it takes a dump?

4) Is there a strong reason for not venting through the roof, which is a much better way to do it.

5) I don't see UPC approval.

6) I am old school and hate AAVs, but, there are two in my home because of log construction limitations.

Don't meet your prereqs. That TrapVent needs perfect alignment of trap adapter with tailpiece.

The Rectorseal 97402 Magic Trap with the Rectorseal 97400 AAV, if the AAV clears the bottom of the sink, could add the vent you need. It would take more room, but it does not need perfect alignment.

I have not used or seen one of those either. Post a photo of what you end up with.

More BS from Studor!

5) I don't see UPC approval.

https://www.ipscorp.com/pdf/studor/STU021_TrapVent_web.pdf shows the UPC approval numbers on the bottom of page 2.

I saw those upc numbers . It may be legal in upc country. there are a few things to know about UPC code It might be in the latest and greatest code but many times the latest code has not been adopted by your locality.
Another thing is I remember a controversy as to whether an AAV was nessesarily legal and some jurisdictions were challenging some technicalitys of the code . I dont know if it was ever clarified in California.
I still think they should be avoided but thanks for bringing these items to attention

Venting through the roof is not possible, but I've heard what I need, will just use a regular AAV and think I if I have enough vertical clearance will install under the (floating)vanity and keep it out of the wall for access and build a faux wall to hide everything. Any recommendations beyond the rectorseal?(thank you for that) Would like to avoid any brands/models known to fail frequently. Is rectorseal better than oatey?

 

[Coolwhip]

Also, what do you guys think about flat p-traps for tub/shower? I'm not working with much space there so it'd be convenient but if you say avoid I'll make a regular trap work.

 

[Jeff H Young]

never used them but someone else should have recomendation. good luck sounds like your in tight spaces!

 

[Terry]

It would be very hard later to snake a flat p-trap. Does anyone in your family have hair?

 

[Coolwhip]

My wife has long hair, I'll keep that in mind.

That literature does not show UPC approval. It shows compliance with ASSE, NSF, and ICC approval, but I don’t see the UPC stamp here anywhere.

 

[Jeff H Young]

Are AAVs actualy approved and non deniable or does inspector need to give ok ? Ive never been sure with UPC

 

[Paulypfunk]

Each municipality has final say on what they will allow, they can make code that is more restrictive than national or state codes.

For instance, we use them in seattle, but certain uptight smaller local towns might not. Bellevue across the lake for years did not. Both adopted the UPC but added their own layer of addendums.
