First time poster, long time reader.
been googling back the past threads on high pressure and I'd love to get
some of your input on the situation as well
When I first bought this house (8 months ago), when ever I would turn on
any faucet in the house after the water system had not been used for a while
I would hear a knocking noise comming from under the floor close to where
the water leaves the hotwater heater and enters the house. This would happen
when the water was flowing, not when it stopped. (heater is in the garage,
I am in TN)
The kitchen faucet, the closest to the water heater makes a humming noise
whenever it is turned on regardless of prior water usage, this stops when
the screen is removed. I thought that maybe I had high water pressure, so
I bought a simple guage from Home Depot, I screwed it onto the drain valve
of the water heater and I got 120 psi, I checked outside on a bib and got
the same 120. The next morning I checked before any showers or water had
been run for the day, and got 100, then after 2 showers and reg morning
activities I read again and got 80.
I'm not so sure about the difference in the readings, but each reading has
been above what I've seen as the "norm" If I install a pressure regulator
will that decrease the flow in the back bathrooms?
House is all 1 level with no basement so piping is run pretty much
horizontally thru the whole house.
haven't noticed any other problems aside from the knocking noise. I tried
to add a few clamps to the pipe where the knocking seemed to be comming
from, but that did not seem to make any difference. I can't see the pipes
physically move when the noise happens.
The problem seemed to be worse during the summer and now into the fall it
seems to happen less.
should I install a regulator? or should I try and clamp the pipes down
some more under the house?
If I install the regulator will I be able to open it back up to the same
pressure I have now if it adversely affects flow in the back bathrooms?
Thanks for all you input
