Toilet Leakage... Toilet is so noisy

Imagine you are home alone or just watching TV with the family in the living and constantly there is this noise coming from the bathroom. You are pretty sure the flat is not haunted. So you go and check it out and turns out the toilet is working hard - there;s a constant leakage of water either through the overflow pipe or into your toilet bowl!

At first, you choose to ignore it. But soon, it bites you in the a $$ because you can't sleep due to the constant noise at night and the increase in water bill (just imagine that you are constantly flushing you toilet 24/7!) that you could've spent on nicer bottle of red.

So how can you go about fixing? First we need to identify the issue. For most cases of leakages the reason rests with fill valve malfunction. Although it could be the case that the toilet flapper has deteriorated over time because of the  toilet bowl  cleaners or chemicals that you have used. (The flapper is a rubber mechanism in your toilet that opens to let water out of the tank when you flush and closes to allow it to refill.)

Other symptoms include overflow of water tank (much bigger issue) or bubbles coming up from the bottom of bowl.

The fill is connected to the water supply and fills the tank with water after it has been emptied by a flush, activated by the flush valve. The bowl will flush as long as enough water gets dumped into it. As the tank fills, it pushes the filler float to top adjusting the lever. The pressure seal will be in action which cases the fill valve to stop filling the tank.

Before we stat, there is always a risk with DIY going wrong. So if you are not sure? CALL US! Also, there are different brands/ models of valves and toilet settings so it may differ a bit. But in general should be similar. T be clear. Below illustrate the fluidmaster system.

  1. Firstly, you need to turn off the water supply and flush the tank

  2. Lift the water tank cover, sometimes you need to unscrew the cover of the flush button

  3. You'll then see the below, reach inside the tank under the float cup and lift it up (the black one on the left). Turn clockwise and unscrew the top. You should be able to lift off the cap and level from the stem.

The left is the fill valve and the right is the flush valve linked to the external handle.

4. For toilets that have been used in years and rarely cleaned, you will see some sediments or debris. Clean it out if you see it, as this could cause the deterioration of the pressure seal (rubber disc with pin coming through)

5. To get rid of the sediment and debris, hold a plastic cup upside down over the exposed opening of the valve and turn on the water supply full force for 10-15 seconds, allowing the pressure to free any debris inside the valve inlet. (BE VERY CAREFUL on this step, otherwise, you'll get soaked!)

6. Check the pressure seal, if it is worn out, replace it.

7. Resemble the way you took it apart. And hopefully it should stop the leak.
