In response to Re: Does 90 psi require a pressure reducing valve?
: I have 90 psi pressure measured in my basement. According to the town and the water company I dont need a pressure reducing valve at that pressure (I did not think to ask what pressure I would need one).
: I'm somewhat surprised by this because they are pretty particular about sprkinler systems (RPP valves are required as is a yearly test by the water company)

: Does that seem too high? Am I going to have long term damage to my appliances with 90 psi?

: Thanks,
: Mike

Plumbing code here specifies that incoming water pressure should not be above 80 p.s.i. inside of a building. If it is, a water pressure regulator is required. Check with the plumbing inspector in your area to confirm what local code dictates.
