How to fix a noisy toilet

Is your toilet is making a lot of noise when filling the cistern? This can be particularly annoying & easily fixed with FlushKING.

The noises are often just down to the flow of water, but in some cases, if the pressure in the water pipe supplying the cistern is too high, the ball / float can start to bounce up and down on the flow of water and send noises though your entire plumbing system (known as hammering).

As the water level in the cistern rises, so does the float on the fill valve. Once the float reaches a preset height (determined by the internal overflow level on your flush valve.) the valve is closed by the float.

You could also have the sound of a water feature running, as your old fashioned ball valve fills from the top of the cistern cascading the water down into the cistern splashing around.

Step-By-Step Guide to help diagnose the problem

1. Check your existing valve for dirt and debries, cleaning this out could solve the problem

2. Check the valve diaphragm is not split or perished

3. Fit a pressure reducing valve on the supply pipe to reduce the water pressure to your cistern

4. Ensure your fill valve is one that works on high and low pressure

5. A simple fix can be to reduce the flow of water by turning the isolating valve a quarter turn

6. Replace your old low pressure ball valve with a new Fill Valve

The Environment Agency has developed a methodology for identifying and classifying relative levels of water stress in water company areas in England. The Government has used this map to designate areas of serious water stress for the purpose of accelerating water metering.
