Home plumbing maintenance can be a challenge but updates in manufacturing and design has helped to simplify the parts and the installation process for most DIY homeowners. Many new toilet inlet valves now require no tools to install them; installation of the new valve is by hand.
Remove the toilet tank lid and carefully set aside on a soft surface out of the work area.
Shut off the angle stop supplyinggwater to the inlet valve. Disconnect the water supply tube from the inlet valve and angle stop with pliers.
Flush the toilet to remove as much water as possible. Soak up remaining water in the tank with a hand towel. Carefully detach the small black rubber refill tube from the flush valve standpipe by hand.
Loosen the inlet valve's locknut under the tank with pliers. Unscrew the locknut by hand and lift the inlet valve out of the tank. Clean the area around the inlet valve opening of any debris with a hand towel to ensure a good seal for the new inlet valve.
Slide the shank washer, bevelled side down, up on the inlet valve threads.
Insert the new valve into the opening in the toilet tank with one hand. Screw on the locknut with the other hand and tighten with pliers if necessary. Adjust the height of the new inlet valve to the manufacture's specifications.
Connect the valve's black rubber refill tube to the hose port on top of the valve, and then to the overflow tube of the flush valve with the holding clip provided.
Install a new water supply line. Screw the small end of the water supply line onto the angle stop and tighten it with pliers. Fasten the larger end on the new toilet inlet valve by hand.
Turn the angle stop valve on slowly and let the toilet fill. Flush the toilet a couple of times to check for leaks around the supply line and locknut. Replace the tank lid.
- If your angle stop does not shut off all the incoming water, you may need to shut off the main water valve to the home.
- This is an easy project but it does require that you bend over the toilet bowl. If you are not comfortable with any of these steps, please call a qualified professional.
