The only other thing that could have been done in that situation would have been to install a PRV as the street pressure was already at 75PSI. At that pressure the valve is going to piss every time a fill valve closes from the spike.

The valve you use from barnett is not listed for what your using it for.
The second part of your post is why a tanks better....it can be set at the proper psi and it will control the expansion more precisely. I'm not asking you to change but your way has its problems too and shouldn't be considerd the best way.

Yeah, until it fails and fills up with water. Then that 90 PSI will be nothing compared to the 150 PSI the system will see due to uncontrolled thermal expansion. Ever see what cpvc pipe does when subjected to 150 PSI at 160 degrees? Can you say flood?

Nah, I'm good. If the inspector/home owner doesn't like the valve set at 90 PSI then the HO will be paying for a pressure reducing valve.

A valve fails safe, a tank does not. Now if you want to install a tank AND a valve then I'm right there with you. IMHO though, the valve is the most important component and is not omit-able in a closed system. Period.

Well its not approved for thermal expansion control by itself. My guess is it acts too late is the reason why. Its not reliable precise control and a tank is. Tanks dont fail safe but yours fails everytime the pressure goes north of 80psi and that could be happening daily and it fails to comply. Nobodys asking you to change but just acknowledge your exceeding the psi and thats not proper.

Well, if it's not approved for it, then maybe you should move here and make a fortune changing out the tens of thousands of them that were built (with a building officials endorsement) into new homes in the central Florida area.

So thats how you justify exceeding the pressure requirement by 10psi? Tens of thousands of installs doesn't make correct. That particular valve is not approved for it....some are but cost more than 7.00

Sounds like you need to write the Florida code counsel a letter as this seems to bother you and only you.

No need to write the letter its already written in the code as 80psi. It doesn't surprise me its not enforced. A bladder tank offers more precise control and when your at the upper limits of the allowable pressure it matters.
