The water pressure in my home is about 80 - 90 psi. I have an expansion tank connected to my electric water heater and I have a watts pressure reducer after the water meter. When I open a faucet, the water runs normally for about 5 seconds and then you notice the water pressure change and decrease. I look at my water pressure gauge and the water pressure is reading 20 psi. Is it normal for water pressure to drop so much with just opening one faucet?
