I agree the plumber’s first task before installing supply piping in the structure is to test or at least verify with water department for adequate water supply and delivery pressure. Even if the plumber did not test/verify pressure before installing supply piping, the plumber should not have left the job without checking the end pressure.

High water pressure has a very bad effect on the operation and life of appliances and fixtures. Unfortunately, most residential building projects except for multi-family housing on public water there is no requirements for installing a water pressure gauge unless home is getting water from private well.

Maybe a request should be made to update code to require water pressure gauges in all water supply systems regardless of occupancy.

When I’m performing a final inspection in an area that I personally know has high pressure issues I will require a pressure verification before issuing occupancy certificate.
