How to change an inlet (fill valve)

Replacing an inlet valve is very simple, but you do have to take a few steps before you start, to avoid spilling water on your floor and to make the job easy.

1.  Turn off the water to the toilet 

2.  Remove all water in the tank by flushing the tank until as much water as possible is removed, and then using a shop vac or a sponge to remove the remaining water.  Once the tank is dry, you can proceed with the change.

An inlet valve is connected by a plastic nut at the base of the toilet tank.

(Note: the design of some 2-piece toilets makes it difficult to access the inlet valve. If this is the case you may need to remove the tank from the bowl to gain access to the inlet valve.  Each time you remove the tank from the bowl it is a good idea to also replace the tank to bowl seal to ensure a good tight fit.   For instructions on how to do this, please click here).

Turn the nut in a counter-clockwise direction until it is completely removed from the lower portion of the inlet valve.  Set aside.

Reach in to the tank and pull out the inlet valve.  If you need to clean the inlet valve, rinse under water until debris is removed, or if it has calcified from hard water, you can soak in a 50-50 solution of water and vinegar for 30 minutes and then rinse again.  Repeat as needed depending on the degree of dirt/calcification on the valve).

Replace the valve, or if installing a new valve, insert the new valve back into the mounting hole in the bottom on the toilet tank.  Screw the plastic nut back on to the bottom portion of the inlet valve.

Turn the water back on and watch to ensure that that the water refills properly.  Once the water is refilled, replace the tank lid and you are done.
