Thumping in the kitchen water lines - American Standard Kitchen Faucet 6310 020 White Easy Touch Pull-Out Kitchen...

Yes, the thump is water hammer caused by the solenoid shutoff valve in the washer closing abruptly when the tub is full. Water hammer stresses the piping joints and could eventually cause a leak. First, make sure that the piping is supported properly to restrain any excessive movement. If the thumping persists, you'll need a plumber to install an accumulator or 'dead end' pipe in the line to help dampen the shock of suddenly stopping the flow of water.

to reduce the 'thumping' noise, open the supply valves more. If they are already at maximum, you may have a restriction further up the supply lines. Thumping is typically caused by unbalanced flow around the seat and washer, usually caused by restrictions.

you have air in line
1. turn off water under sink
2 turn faucet on full
3. turn on valves under sink water will sputter then run solid
Hope this helps mike

If it is the water line you speak of the I would just let the water flow until the lines are clear. Otherwise I would be looking at the fan motors mocking the noise. There is no possible way for air to get into the refrigeration lines. Good luck

The thump comes from one of several areas. Air pressure in the hand sprayer is one.

But I suspect that you need to check your shut off valves. Old style (non ball) valves fail during this event. There is a little washer that deteriorates, over time....
Then you need to install a faucet, you shut the valves and the little washers either break or come loose. When they break, little pieces go up and clog the faucet.
The other failure is they partially block flow afer coming loose, and cause a thump, like what you describe. To fix, shut off main water in the house and DRAIN what you can. Best to replace with whole new valve, but next best is to replace the guts, unscrew and take to hardware store and get new stem and guts. Inspect the seat, often they get damaged and pitted. Nor necessarily an issue on this install, as the valve in normally open...

your hot water causing a thumping is just built up air in the line, you can install a devise for this ,, also,, make sure your water lines are strapped down ,,

hello, you may have a air pocket in the line try shutting of the water supply and then sqeeze the handle and slowly turn the water supply back on with the hose handle squeezed on till the air is forced out, hope this helps

There is a small diverter valve on the faucet underneath where the hose connects too it needs to be replaced depending on the age of the faucet I usually recommend replacing the entire faucet with another Moen product

Is your supply line plastic or copper? If its plastic then that can absorb a smell. There is nothing in the icemaker that would make it smell. You may need to replace the supply line and the inlet line that feeds the icemaker. Is there a smell in the kitchen faucett?

I hope this helps.
Step11Turn off the water supply. You'll find a shut-off valve under your kitchen sink. Once the water is turned off, open up the kitchen faucets to allow the water remaining in the pipes to drain way. Step2Catch the drips by placing a bucket under the hot water supply line, located on the left side of your sink. Even a minimum of water can cause a mess and be potentially damaging. Step3Use a wrench to remove the compression nut that secures the hot water supply line. Let the disconnected section fall into the bucket. Use the wrench to loosen and remove the nut at the other end of the line and remove it as well. Step4Repeat Steps 2 and 3 for the cold water supply line. Step5Replace the cold water supply line. Hand-tighten the nuts on both ends, then use the wrench to tighten the nuts completely. Repeat the process with the hot water supply line. Step6Turn on the water supply and test for leaks
