How To Clean A Toilet Fill Valve

Toilet fill valve cleaning does not require complicated steps and can be done easily following the following steps

You’ll Need These Tools to Clean Your Toilet Tank:

  • White vinegar (depending on your tank capacity)
  • Gloves
  • Cleaner
  • Sponge
  • Scrub Brush with Plastic Bristles

Step 1: Turn Off the Toilet’s Water Supply

The first step is to turn off the water supply. By using the water control valve to stop the water flow, you may easily drain the water tank. Find the valve, which is typically around the base of the toilet or on the wall behind the tank. To stop the flow of water, turn the valve clockwise.

Step 2: Drain the Tank

The tank’s lid should be removed and put out of the way. Until the tank is totally drained, flush the toilet. It can take two or three flushes to completely empty the tank, depending on tank’s capacity.

Step 3: Unscrew the Fill Valve Cap on the Toilet

This fill valve’s top gray cap can be removed. Simply grasp and hold the fill valve’s shaft with one hand while rotating the cap of the valve counterclockwise.

Step 4: Clean Fill Valve Toilet

If you live in an area where there is hard water there are chances that the fill valve’s exterior may have calcium and mineral buildup, in that case, you should clean the valve with vinegar and an old toothbrush to dissolve and remove the buildup. After cleaning the valve with warm, soapy water, rinse it with fresh water.

Additionally, you can also place an upside-down cup over the head of an uncapped valve, turn on the water completely for three to four seconds, and then turn it off. To clean the valve, repeat this two times.

Any sediment or debris that might have been impeding the fill valve’s functionality should be flushed out by this water burst. Once it has been cleaned, you can reinstall the fill valve’s top and tighten it with a clockwise twist.
