Thanks for all the help guys.... It makes since that UL would approve it but thats not enough. Im going to leave it for now, even though I know I shouldnt. The house is a rental and the management co is my customer, not the tenant. There is no risk of it causeing damage to the house as it is an outside hose faucet.
The material may be fine. However, engineering a correct adhesive joint involves far more than the material. For example, for adhesive purposes, "clean" means something entirely different than it does for sweating. Also, the bond line thickness must be very specifically controlled in any adhesive joint, and again, it's different than sweat joints. With adhesive, there's pretty much ONE way to get it right and a million ways to get it wrong. In a factory, they can control the process (even though some don't do very well)... it's more or less impractical to do that reliably in the field. None of this matters much if you're gluing the handle on your weedwacker.... but I wouldn't use glue for important applications.
OK lets move on to flexible supply lines for water heaters. Some parts of the US requires them here in Illinois it is against the code as well. Illinois wants the water and gas pipe to the water heater hard piped. Must use a union on the piping to be able to change water heaters easily. But the supply houses sell the flexible piping. My original post is they can sell anything they want, it just not legal for use in the Illinois plumbing code.
Why would Illinois make it legal to replace the "Chicago loop" (what we call island venting here) with aav's.
I have much hate for those flexible water heater supply lines, but I also don't live in earthquake country. my boss always adds them to his generic trim package orders, anymore I dump the things at the shop for someone else to use.
I have ALWAYS been told that in a HUD approved dwelling NO local codes may be applied. I know local codes can disallow hud homes if they arent the proper wind rating, but with all my work around mobile homes I have always been told thats it..... Speeding is illegal, so why is it legal to sell the garbage that kids buy now a days to make a honda go over 100.
Is there a place to see the current mobile home codes online?
Sort of off topic I know but sort of irrelevent too.
