Default Bidet seats and cross connection...

Jim, Master plumber from Wisconsin here,
Has anyone here had a problem with bidet seats as a cross connection issue (like Toto or the cheaper ones on Amazon) I was asked to put one in a nursing home but thought this sure has to be a cross connection with the wand sticking down in the bowl? NON continuous Backsiphonage and sewer is high hazard, right? I didn't want to put it in and told them i would be back in a few days. Toto complies with ASME A112.18.1/CSA B125.1 “Plumbing Supply Fittings” any help would be appreciated, Getting no help from local and state, thanks Jim

His other identical post: https://www.plumbingzone.com/f2/bide...8/#post1217648


1st, please don't double post, just pic a spot and post once. Either way we will see it and if it's wrong an admin can move it.


As tango has mentioned several times, he refuses to install bidet seats as almost all of them aren't properly approved or approved at all.


That said, if it's a toto it's probably okay. Have you tried calling/emailing toto? I would think given how large they are that they would have gone through the proper processes and will tell you how to properly install it.


Or you could just install some vacuum breakers. I know many bidets have 1/2" fittings like you would find on a shower head so you could use two Zurn Z7000-Vb fittings.


https://www.faucet.com/zurn-z7000-vb-n-a-vacuum-breaker-for-1-2-wall-hose/f2907630



Or you could install some hard piped vacuum breakers like the Zurn 59520004.


https://www.kullysupply.com/zurn-59520004-vacuum-breaker-assy-rc-1-2-npsm-x-1-2-npsm



Personally I might use two wolverine brass sillcocks on the wall with two standard hose fitting vacuum breakers and a 3/4" female ght x 1/2" fpt adapter followed by a 1/2"mptx3/8" compression adapter. Sounds a bit convoluted but if it doesn't work out then they are just left with two normal, commercial, sillcocks on the wall which have a lockshield stem allowing the handles to be removed for use with a square key. And if the vacuum breakers wear out they are easy to replace with a very common part.

Those type VB's for that use would not be approved in Illinois. Not a high enough safety rating. Have not looked up the specs for a Bidet in a while.


Most similar I can think of would be an aspirator in funeral parlor pre area. You may have an atmospheric in line with no control valve after the VB, mounted 7' above the floor. The control valve would be flush or wall mounted below at hand height and before the VB

When it comes to bidet seats with a built in wand that comes out and sprays and goes back in then if it is an approved product from a name brand I would not have a problem putting it in.

just have the customer squat over the kitchen sink and use the sprayer from the sink, its protected against backflow( no pun intended, well maybe) and your problem solved...

From Toto's washlet website page:
Meets or exceeds ASME A112.19.2/CSA B45.1
• Certifications: IAPMO(cUPC), EPA Watersense, State
of Massachusetts, City of Los Angeles, and others
• Code compliance: UPC, IPC, NSPC, NPC Canada,


That may not satisfy all of the US (or Canada), but it does cover a big chunk.
