Reasons Why a Bidet May Make Noise

A bidet may make noise for a variety of reasons. The most common reason is that the water pressure is too high. It could also be because you have a bad shut-off valve or even leaking valves and hoses. Below we cover the most common reasons and how you can fix them.

High Water Pressure

The most common reason why your bidet is making noise is that you have high water pressure in your home. You might also hear a humming noise from your faucets and other appliances connected to the water line. Try lowering the water pressure in your home to see if the noise disappears.

If you are unable to lower your water pressure you might have to install a pressure regulator. This is not something you should attempt yourself, it’s better to consult a professional.

Bad Shut-Off Valve

The shut-off valve is the valve that connects to the valve that connects your bidet to the toilet’s water supply. If you are experiencing noises from your bidet, it may be because you have a bad shut-off valve. Try replacing the shut-off valve to see if the noise stops.

Another reason could be the adapter that connects to the shut-off valve. Try replacing the 3/8″ angle stop with a 1/2″ angle stop if your bidet has a 3/8″ to 1/2″ adapter, this may help get rid of the noise.

Leaking Valves

If your bidet is making noise, it could be due to a leaking valve. When a valve leaks, it can cause the water pressure in your bidet to drop, which can make the bidet make noise. If you think your bidet’s valves may be leaking, you should check them for leaks and replace them if necessary.

While you’re at it you should check all the connectors and hoses to make sure there are no leaks. You should also tighten all the connectors as loose connectors could cause noise as well.
