Pressure issue in residential home

Hello all,

Thanks for the previous replies on my PEX system.

I have been in this home for 1 year. In the last month we have had a pressure issue. Pressure at an outdoor spigot is 60psi, drops to 15 when an indoor faucet is opened. Pressure goes back up in ~3 minutes if the faucet is turned off. Obviously we see pressure drop while showering/etc.

I have not done any recent plumbing changes (changed the kitchen pipes to PEX 6 months ago from polybutylene). Line from meter to house is 3/4 inch polybutylene, attaching to a pressure regulator (see pics). Neighbors have no pressure problems. No leaks. There is no expansion tank on the hot water heater (house built in 1992).

Any ideas? Bad regulator?

Thanks again, you all are loads of help!

A regulator with a clogged strainer and/or faulty diaphragm seal wil cause you symptoms. While in theory, it can be rebuilt, I would not even consider it, as the success rate is very low. You can get a reglator for about $50 and it is an easy change out.

Excellent, that is what I will do, and will let you know what happens.

Thanks!!
