We are in final stages of spec/pricing a new 21 for delivery in May 2019. It makes sense to me to get them to do it during our build. So I will be asking ETI to do so. I can't see why they should object on leakage grounds as these are installed all over the world without issue providing the correct install process is followed.

Did you have any luck with this?

It seems that we never stop learning - we just get older.

The installation of a S trap is illegal in the United States. The kitchen sink in Escapes are installed using a S trap.

The installation of a Hepvo valve for the kitchen sink meets US plumbing code.

Of course, buuilding codes only apply to RVs insomuch that their standards have been adopted by the RV industry regulatory body. In the US, that would be the RVIA. They follow NFPA 1192, section 7 when it comes to plumbing requirements - and yes - according to that section, an S-trap is prohibited.

Escape being a Canadian RV builder doesn't use the RVIA standard, but their standard is similar.

Actually, Escape is required to meet RVIA standards because they import to the US. The only way to get around RVIA standards for Escape would be to manufacture two versions of the trailer - one to meet Canada standards and one for US export.

edit: Donna D corrected me rightly - The standards that have to be met are NFPA 1192 and not RVIA.

NFPA 1192 Standard on Recreational Vehicles

7.4.4.4 Full “S” traps, bell traps, drum traps, and crown*vented traps shall be prohibited.

7.6.6 AntiSiphon Trap Vent Devices. An antisiphon trap vent device shall be permitted to be used only as a secondary vent in accordance with the following:
(6) The device shall be installed in an accessible location that permits a free flow of air.

Why? RVIA is not a government authority. It's an association that a manufacturer pays to join. And ETI isn't a member. But then neither is Scamp or Casita. Oliver is though.

I think RVIA is a joke. THEY decide what the standards are and have no authority to back it up. Follow the money!


I even made a sticker!

Sorry Donna, I should have said that Escape doesn't meet NFPA 1192 which is the regulating government standard. RVIA doesn't write the standard but refers to NFPA for the standard. NFPA covers fire, plumbing, electric, etc. codes which by law govern installation standards for the US.

So yes, Escape is not a member of RVIA but are still required to meet all NFPA 1192 standards and they do not.

Here is the Oregon law reference for compliance with NFPA 1192.

NFPA 1192 "This standard establishes fire and life safety criteria for recreational vehicles to provide protection from loss of life from fire and explosion."


Maybe because a plumbing issue would only make a mess, but never fire or explosion?


I'm not going to become a member to read it:

No, I corrected you rightly, by citing NFPA 1192.
