Is Your Toilet Making Noise? Discover 5 Likely Causes

Approximately 400 million liters of water are lost through the toilet leakages across the UK each day! These leakages are mostly caused by faulty accessories and systems. Faulty toilets need to be repaired to avoid high water bills and water wastage, not to mention the inevitable structural damage that follow.

The easiest sign of a faulty toilet is noise! Yes, abnormal noises when you floush your toilet could be indicators that something faulty needs to be fixed. The earlier you get it fixed, the better. The following are the 5 toilet making noises, their likely causes and also how you can easily correct the problems at home.

HISSING;  

Does your toilet make hissing noises? This is due to the air or water that is flowing into your water tank from the waterline. All toilets have a refill valve. After flushing your toilet, the refill valve controls the amount of water that will get back in the tank. In the event, it does not work well you may have too much or too little water after flushing your toilet every time. The refill valve is designed to automatically shut off depending on the level of water in your tank. If the refill valve does not shut as it should, it allows a little water in the tank which will cause a hissing sound.

You can try these methods to rectify this problem.

  1. Remove the lid of your toilet tank. Check whether water is flowing down your overflow pipe. Adjust the float, if you have a ball float, unscrew it and turn the armature to ensure its angle is on the top of your tank. This will reduce water flowing which increases your water bill.
  2. If the first step does not work, check whether water is clearly flowing from your refill valve. Remove anything that could be causing blockage of the hole to rectify this noise.
  3. If you still hear a hissing noise then the problem could be the main toilets water supply. This could be due to air in the system or faulty plumbing from the onset. You may require a plumber to rectify this.

GURGLING

Gurgling

Toilet gurgling is also a very common toilet making noise. It’s caused by the blockage of a toilet line. The clog will make the air in the line flow negatively and thus, push backward causing the noise. This gurgling noise could be caused by a clogged drain line or toilet, blocked vent stack, or a problem in the sewer line.

You can use the methods below to rectify this noise:

  1. Unclog your toilet by trying to dislodge anything that may have blocked your toilet. You could use an auger to try to dislodge items causing the blockage. If this works, you need to avoid in future flushing items like wipes, feminine products, paper towels and cigarette butts. These items may go down the drain when flushed but later cause problems by blocking the lines.
  2. Unblock your vent stacks. Vent stacks are the vertical pipes that lead to your roof. They are designed to control the air pressure in your plumbing system and equally release all the exhaust gases. They may sometimes get clogged by the leaves, rodents or animal nests causing negative pressure. If the clogs are just at the top of your vent, you can just clear them out. If they are in the pipes, you may require calling a professional who will remove all the clogs for you.

If the two methods do not work, the problem may be due to clogs in the drain line or mainline. This may be difficult to unclog without the help of a professional. A clog in the drain line is easier to unblock than that of the mainline. A clog within the mainline will probably affect your neighbors too and you may require contacting the municipal to rectify this.

GHOST FLUSHING

Ghost flushing can be a very spooky nuisance in your toilet. It’s caused by long periods of water leaking from your tank. The leaking is mainly caused by your toilet flapper breaking down and thus allowing water to leak to your toilet bowl. Ghost flushing is caused by floats that need adjustment or a deteriorated flapper.

  1. To check whether your toilet flapper has deteriorated, put food dye in your toilets water tank and avoid flushing for at least 30 minutes. In case the water in the bowl turns the color of the dye, it’s due to the flapper leaking. To correct this, lengthen the chain that is holding your flapper by one to two links. A flapper will not fit in the siphon hole if the chain is short and consequently causing a slow leak. If the water discolors after this test you can shorten it further then consider replacing your flapper if does not work.

FILL VALVE HISS

If your toilet has a fill valve hiss, this toilet making noise will sound as if the air is being forced to move through it.

How to correct this toilet noise:

  1. Step one, turn off your water supply then flush the toilet to empty the tank.
  2. Using your right hand, under the float cup reach inside the toilets tank and lift it up. On the gray shaft keep the float cup up all the way without allowing it to drop or turning the valve shaft.
  3. On top of the toilets valve cap hold with it your left hand. Turn counter-clockwise the arm and cap to unlock. On the valve body, you will now manage to lift off the lever and cap.
  4. After removing the cap assembly, check whether there is debris on its seal; ensure the valve portion remains inside the tank.
  5. For about 10-15 seconds, on full force turn on the toilets water supply while holding in place the toilets cup to flush out all the debris trapped in. if the seal is in good shape reattach it to the cap. If the seal is damaged, replace it before reattaching.
  6. Next to the tube refill, place the cap arm to reassemble it . Turn the arm clockwise while pressing down to lock the cap.

WATER RESONANCE

Water resonance also known as a water hammer is described as a very loud bang in the toilet pipes. Often, it occurs due to a pressure surge when flowing water suddenly changes direction or stops. It’s an indication there is an obstruction in the water pipeline. The effects of the pressure wave could be vibrations, noise and pipe collapse. Use of arrestors, accumulators and restrictions of water flow rate are some methods you can reduce the water hammer effects.

How to rectify this problem:

  1. Slow down water flowing in by reducing its speed by using regulated fill valves, this stops the noise.
  2. If the above does not work, replace your shut off valve placed at the wall as it may have debris that has buildup in it.

Next time you encounter the above noises rectify them with the above methods. Ensure you do not put off the above problems to avoid water wastage.
