 House water pressure drop
Author: yonson (SC)

Hi folks. In sc here. Public water. No expansion tank on my water heater. When I turn on a faucet the water pressure drop after about a second. No other fixture is open. Happens all the time. How do I retain the water pressure at my fixtures from the time I open them until I close them? Happens in all fixtures.

when you say "all fixtures" do you mean toilets, showers and outside faucets?

usually, it is caused by a defective pressure reducing valve in the system

Has the main shut-off valve been checked, to see if it's fully open? What type of valve is the main water shut-off? If a gate valve, maybe it's broken.
