WOW Well mostly it is 50-80 here in Berkeley and around. But we have hills so
pumping stations are required. If you live near one your PSI is very high. I
put pressure reducers on lots of clients homes for that reason. The only
reason it would be low here is if the water source is going through the house
and the valves are out back. Galvanized pipes are reduced by rust so the PSI
can drop. If its bad, I put a new copper line in the house first. I assume
there are some communities that have lower pressure where I live, but I have
seldom run into them .
