all areas of the house have high initial water pressure then the pressure/flow drops after a few seconds. I have just replaced the pressure regulator thinking it might have been bad. Was also getting major hammering/noise when a faucet barely turned on (thinking it had too much pressure on it) Any other thoughts? I am definitely not a professional plumber, just a pretty good handy man. So I would really appreciate any assistance or ideas. Below are the house stats:
3/4 in copper in mech closet. presumably 1/2 in. to services
18 yr old house on slab, single story. no thermal expansion tank. hot water heater fairly new (built in 1994 according to EPA sticker). On unregulated faucet(front of house) great pressure/flow.
My wife and I just bought this house, so I can't give anymore history.
Thank you very much for your time. My email address is snipped-for-privacy@earthlink.net
