I installed a new kitchen sink faucet, and now it makes a weird thumping sound every few seconds when the water is turned on. I adjusted the water pressure, which slowed the noise repetitions down a little, but it’s still there, and terribly annoying…
Was thinking there was an air pocket in the line somewhere.. or something, I’m not a plumber *shrug*
What can I do to make this noise go away?
Thanks!
If it is a washerless faucet, you may have a dry O ring. Shut off the water and remove the valve assembly. Apply silicone grease to the rubber parts and reassemble.
Make sure that you have not inadvertently loosened a strap or hanger on the lines while jiggling them around
TURN ON YOUR HOT WATER AND LET IT RUN A FEW MINUTE EACH DAY YOU DO HAVE AIR IN LINES
Yep, that is air in the pipes. run the water it may take awhile to go away.
Off the top of my head, I’d say you STILL have air in the lines,.
let both faucets run for 5 minutes…… that should clear it out.
Air in the lines
If the noise comes from the hot water side you might have too much air in your hot water tank. Just go out there and lift the handle on the "pressure relief valve" a couple of times. Make sure you have a drain line attached to the outlet otherwise you could get wet and scalded. You are supposed to operate this valve once a year anyway.
If this does not work you may have lost the air cushion in the top of the tank. If this happens you would get thermal expansion noises because as the water heats up an expands it would have no place to go in a hydraulic system. There should be air in the tank above the relief valve to allow for thermal expansion. A fitting leak at the top of the tank could cause the lose of air. In this case you would have to drain the tank completely and refill it trapping air and compressing it into the top of the tank. Then open the relief valve to make sure water comes out at that level.
FYI..Hot water does not flow from the top of the tank. It is drawn off from a "dip tube" that extends about 3/4 down into your tank so the air cushion is trapped (if there is no leaks at the top of the tank.)
