In our garage there is a cold water supply valve for our house. Whenever we
run water in the house, flush a toilet, or run the washingmachine, the
valve makes a loud pumping noise (whoosh-whoosh-whoosh) that is audible
inside the house.
What causes this? Is it a defective valve? Can it be fixed?
Thanks for any help.
In my limited experience, it was easier to just replace my PRV with a new
one than rebuild the old one. The price difference was something like $40
vs. $60, kit vs. new valve. No warranty on the rebuild, no guarantee that
the rebuild would even work.
Hardest part was adding the access panel to the basement ceiling after
cutting the drywall out to get to the old valve. I made a sliding access
panel since there is no room to lift it up. Came out pretty nice.
It is not a water valve. It is a pressure regulator. Evidently your
water supply has high pressure that can cause extreme wear on valves,
faucets, etc. The Watts regulator controls the supply pressure. YOu
might try changing the pressure setting to see if it helps on the noise
problem. I would not run the supply pressure over 50-55 lbs, 30 would
probably be a minimum.
The valve has a removable stainless steel screen internally. I suspect that
either sediment has blocked part of the screen, or it has grown some
scale from hard water. With the supply turned off, remove the screen (from the
bottom of the valve), clean it and replace it. Carefully. The scale can
be removed by soaking in vinegar.

This unit has replaceable parts without removing the regulator. They
probably have a repair kit available.
Why? What am I missing here? Why should he contact his municipal water
(Also, it helps if you quote at least some of the original post to give your
post some context. I did that for you in my reply here.)
