We have a modular home was plumbed with all pex and CPVC. I have a problem losing water pressure when you turn one thing on that flows a lot you lose water pressure the whole rest of the house. I put a pressure gauge in where the water comes in from the road and when you turned something on I would only get about a 5 psi drop. I went out to wear the garden hose hooks in and opened up the same valve and I got like a 20 psi drop. Any idea of how I can go through and figure out where my restriction is. On city water with no pressure regulator. It's a very small town. I have about 60 psi coming in.

I have no water in my kitchen replaced the faucet and still no water. Water everywhere else in the house help going crazy
