Losing water pressure

[Onion69420]

Hello,

My home is on a well. I've lived here for 10 years and haven't had any water issues.
Recently I started losing almost all water pressure regardless of location, whenever another tap was opened. The water flow is reduced to a trickle. I talked to the plumber at the plumbing store and he said it was the pressure tank. So I replaced it with a similar size tank.
This did not fix the problem.
The pressure gauge will show 40 psi and I'm still losing pressure.
If no other appliances are used then my flow rate is fine. Pressure is reduced when another appliance is used and immediately returns when the other appliance is turned off.

Don’t confuse low pressure with low rate of flow.

10 psi flowing through a ten inch wide pipe would be a very high flow rate.
100 psi through a 1/8 inch pipe would be a much weaker flow rate.

You need to give more info about your entire plumbing system.

Is this happening only with hot water flow, or hot and cold?

It is likely that you have a restriction somewhere.

Clogged whole house water filter.
Clogged water softener inlet screen.
Clogged water softener resin beads.
Well tank loaded with sediment.
Sediment clogging up an isolation valve or shut off valve somewhere.
Water heater nipples corroded inside, openings narrowed.
Clogged aerators on faucets.
A valve that has been partially closed somewhere, then forgotten about.

So it was the whole house filter tucked away in my basement cieling. I wasnt even aware I had one. My sons friends dad is a plumber and he came over and figures it out
