Quick Toilet Fill Valve Fix

The toilet in my bathroom was taking a long time to fill up its tank. This is how I rectified it for the short term

Most toilets have a fill valve that is responsible for filling the tank up with water. The attached ballast controls the start and stop of the tank fill. This valve has parts in it that will wear and tear over time, and these parts or water debris will result in a clog.

Each fill valve is different , but the basic principles are as follows -

  • Turn off the water supply
  • Empty the tank by flushing the toilet
  • Remove the part in the valve that regulates the water flow. This part usually has a rubber gasket
  • Flush out any debris by turning the water back on
  • Put parts back in their original places
  • Turn the water back on

In my case, I had to first snap off the blue cover over the fill valve. After which, I had to remove a tiny plug that attached the ballast to the valve. This freed up the "regulator", which could be removed by turning it counter clock wise.





The next step involved putting a cup over the valve so that the water did not splash all over the walls and floors. I then turned the water back on. Remember to hold on to the cup with one hand, because you are still dealing with enough pressure to pop the cup off the valve. I let this run for around 20 to 30 seconds and this was good enough to release any particles back into the tank.

I put back the regulator, re-attached the ballast and the top cover, and my toilet was back to filling up at its normal speed.
