    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?

    No it is not. Does your PRV have a strainer on it?

    I dont know. This prv came with the house and we've been in it for over 2 years now. The prv only has a pipe on each end.

    Shouldn't these two threads be merged as one¿ I mean we are talking about the same plumbing problem.

    Based on the Diagram, can I easily remove that strainer plug gasket?

    If I remove that, what should I be looking for?

    Likely some debris. Clean it and replace it. I read and answered your first post before seeing this one, so my answer here is just a tad different. Check the strainer.

    More likely the PRV is defective and needs replacement.
