A toilet making an air noise or a whistling or hissing sound is a sign that the fill valve is not closing and sealing properly, and air or water is leaking from the fill valve. If the fill valve isn’t closing properly, begin by replacing it. If this doesn’t solve your problem, call a plumbing professional.

Why does my toilet sound like an air compressor?

When there is high pressure from your pressure tank or water heater, the toilet flush releases pressure, resulting in the banging sound. To fix this problem and get rid of that irritating sound, lower the water pressure in the pipes. A pressure reducing valve can often be found near your main water supply line.

How do I stop the hissing noise in my toilet?





As the high-pressure water passes through a restricted opening, it creates vibrations that you hear as hissing. To replace the valve, turn off the water supply to the toilet either at a wall-mounted shut-off valve or at the house main. Flush the toilet to drain the tank, and then remove any excess water with a sponge.

Is it normal for toilet to make hissing noise?

A hissing sound can mean that the refill valve is still letting a tiny bit of water into the tank because it hasn’t shut off like it’s designed to. The valve shuts off automatically based on the water level in the tank. A faulty valve or one not set properly will keep running.

How do you get air out of toilet pipes?

Start with the faucet that’s closest to the shutoff valve and work your way to the farthest faucet. Open each hot and cold faucet about halfway to let the air run out. Remember to flush all the water out of the toilets, too.

What does a hissing toilet mean?

Toilets make all kinds of strange noises, from gurgling to screaming, and most are related to the movement of water or air. If the sound you hear from your toilet is hissing, it probably means that air or water is leaking from the fill valve. Either way, the valve isn’t closing properly, and the toilet may be leaking.

Why does my toilet make noise every few minutes?





This sound can happen intermittently and occur every few minutes or every few hours. Such a refill sound is usually alerting you that your toilet is losing water, either internally (if there’s no water on the floor or exterior of toilet) or externally leaking if you see water outside the toilet.

What are the symptoms of air in a water system?

However, trapped air can cause irritating problems such as:

  • Excessive noise coming from your walls.
  • Reduced water pressure, resulting in weaker flow (especially noticeable in showers)
  • Spluttering faucets or inconsistent output.
  • Rusting and corrosion in extreme cases.
  • And more!

Why do I keep getting air in my water pipes?

The main cause of air in the water lines is water system maintenance. Cutting off the water supply for a period of time can allow air to enter the system. (Running faucets briefly usually resolves this problem.) Maintenance work on the water main may also introduce air into your system.

Can a gurgling toilet fix itself?



Can a Gurgling Toilet Fix Itself? It is possible the gurgling sounds go away on their own if the drain clog clears itself or you remove any debris from the vent stacks on the roof. If the issue lies in your main sewer line, you’ll need the help of professional plumbers.

Can a full septic tank cause gurgling?

Septic tank needs to be pumped: When your septic tank is too full, gurgling noises will be common with any plumbing fixture or element you use. The tank will be unable to drain, blocking the sewer lines from flowing as they should. You may also notice sewage seeping from the ground or a strong odor outside your home.

How do you fix an airlock in a toilet cistern?

Remove Airlocks In Taps With A Hosepipe
Use a hose clip or tap adapter if necessary. Next, attach the other end of the hosepipe to a nearby tap that does work again, make sure it’s secure. Allow to run for a few minutes; the force from the mains water pressure should be enough to remove the airlock.
