that will be up for debate
In my opinion ...anything above about 90 psi can be considered high
perhaps I am too high at 90 and really 80psi is high..?????
my house has 115.....and I have both the PRV valve and the
expansion tank , and its all been kicked down to 75...
it keeps the system under less stress....this way...
now others will probably chime in and debate this....and that is ok
their are parts of our town that have over 145 psi and the home systems
are under tremendous stress. and really should have both done to them....
but many people dont want to spend the money to upgrade something
that never gave them troubles.....
Its very hard to just say something is now "code" and
attempt to tack on $400 to a water heater estimate.
for a PRv and Themr exp tank.
Usually they claim that they will "get back to me"....click..........
