Why Does My Kitchen Faucet Thump

Thumping in water pipelines is referred to as water hammer, and it occurs when incompressible water abruptly reverses direction.

The most common time to hear pounding pipes is when the water is turned off, and it may also occur near water-using equipment such as washing machines and toilets when the automatic fill valve closes.

The water must abruptly come to a halt, and since it has nowhere to go, it pounds against the pipe’s walls.

A Kitchen Faucet Produces a Thumping Sound

When water hammer affects a single fixture, such as a kitchen or bathroom faucet, you may be able to stop the pounding by servicing and replacing the faucet’s valve. The existing valve may be loose, causing water to flow in and out of the faucet when you turn it on. Occasionally, a kitchen faucet diverter thump that happens when the sprayer is turned on may also be remedied by servicing the faucet.

If the faucet is brand new or if repairing it does not resolve the problem, the next step is to install a water hammer arrestor in the pipes just before the shutdown valves.

Additionally, you may eliminate thumping in the bathroom sink, shower, or toilet by installing a water hammer arrestor; however, you will need access to the pipes right before to the valve, which may require cutting into the wall.

How To Fix It

Water Hammer Is Supposed to Be Prevented by Vertical Air Chambers

Numerous domestic plumbing systems have vertical air chambers strategically positioned throughout the pipe network. The theory is that the compressed air in these pipes can absorb the force exerted by the water as it changes direction. The disadvantage of this design is that the air chambers often get clogged with water, rendering them useless.

To begin resolving a water hammer issue, plumbers suggest totally emptying your water system to remove any remaining water in these air chambers. The pounding should cease after the pipes are refilled and the water shuts the air in these chambers. Regrettably, they will very certainly refill with water again, necessitating frequent repetition of this treatment.

Are air pockets the source of the problem?

Another possibility for a similar hammering sound is the presence of air pockets in your pipes. If the noise begins as soon as you turn on the faucets, air pockets are almost certainly to blame. Thus, to resolve the water hammer issue, begin with the taps closest to the meter and turn them all on one by one. Then, in reverse order, turn them all off. This may result in the formation of air pockets in your pipes.

Half-close valves

While this is not a long-term solution for water hammer issues, it is worth a try until the issue is completely resolved. Water hammer is often induced by washing machines and dishwashers due to the rapid closure of the shut-off valves. Therefore, turn these intake valves halfway on.

Intake connections should be replaced

It may be feasible to replace the intake hoses on these identical troublesome appliances with wider ones.
