Noisy water valve

Post by VidBex
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.

So it's the pressure regulator that making the noise? Not a open/close valve?

I'd guess it's cycling to adjust the pressure. If it's a new noise then maybe you should look for a rebuild kit for it.

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.

Turn off the water (main street) supply, before attempts to work on
it.

If it's a globe valve, I would say that the problem is that the scre
holding the disk in place is loose and the disk is moving back and fort
on the screw

Sometimes the interior washer gets worn and can make loud sounds like
that. Can't say for sure not knowing if it is a globe valve ball valve
or gate valve.

The Watts website says that the N35B is a discontinued model.

Seems like just switching out the existing valve with a new one would be the
easiest option.

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.

Agree.

... I've tapped the side of a valve before (screwdriver handle). It
may just silence to sound the OP hears - if something is blocking the
operation.

True. There are still repair kits for the unit.

IMO, the diaphragm in the valve is worn and brittle...

Needs some TLC on the valve.

*Here's a link to the customer service page with email and phone number.
This unit has replaceable parts without removing the regulator. They
probably have a repair kit available.

OK, this is easy then. If you don't know the difference between a valve
and regulator, it is best to call a plumber. They are fairly cheap and
esily replaced.

Doesn't the OP have a "regulator valve"?

Plumbers are not fairly cheap, most are expensive. But they might be
easily replaced as long as there are other plumbers in the area.

Why? What am I missing here? Why should he contact his municipal water
supply source?

(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.)
