Hope some one can shed some light to my prblem.
Recently my water pipe started make some grunting noise. It sounds
like that you put some heavy stuff on a wood shelf which is going to
crash. I thought I had problem on my floor but find out it is my pipe
later. The noise comes from very begining of the pipe. It is right
after the hot pipe comes out from the water heater. Since both cold
water pipe and hot water run next to each other I can hardly tell
which is making the noise. The noise will gone when I open a faucet
or use my toliet but it comes back after that. I was told that it
could be the air for somehow goes into the pipe. I was suggested to
open all the faucetes and toliet but turn off the main faucet to drain
out all the water and then turn the main faucet back out to let the
water run through all the pipe for a while. I did but it did not
solve my problem. Any other idea?
I recently use a 1600PSI pressured washer. Is it the problem?
Thanks in advance
