Worn out flush valves normally cause toilet leaks, which may lead to a great deal of water loss. They also create a lot of noise and waste, which adds to your monthly utility bills. Corrosion wears down a toilet’s flush valve over time widening the seal located between the toilet bowl and the tank, which allows water to flow out from the tank freely. Toilets are available in numerous designs and sizes but basic toilet repair parts can be used in nearly all types of toilets. You can save a great deal of time and money by learning how to install a new toilet flush valve ,fix a leaky toilet, or install an energy-efficient flush valve.
Things You’ll Need
If you want to replace a worn out flush valve, you will need a replacement flush valve, pliers, a towel or sponge, and a bucket.
- Find the water shut-off valve located behind the toilet. Switch it off by turning it in anticlockwise direction to stop water supply to the toilet. Take the toilet tank lid and place it on an even surface.
- Flush the toilet and ensure that you hold the drain down to drain as much water as possible. Suck up the remaining water in the tank using a towel or sponge. Wring out the towel or sponge in a bucket and continue sucking up any remaining water.
- Disconnect the water supply pipe from the bottom of the toilet where it links up with the fill valve. Use a pair Channel lock pliers to turn the connection anticlockwise.
- Find the locking nuts that hold the tank to the toilet bowl flange.
- Get rid of the rubber washer seal covering the retaining nut to the flush valve found at the bottom of the tank.
- Remove the holding nut using a pipe wrench and get the flush valve out of the tank.
- Fix the new flush valve into the toilet hole inside the toilet tank. Ensure that the end of the flush handle has fitted well into the slot on the flush valve. Fix the valve to the tank using a retaining nut and tighten it with a pipe wrench.
- Return the rubber washer seal to the outside of the retaining nut. Make sure the curved part of the rubber seal is pointed away from the toilet tank. Put the toilet tank over the bowl flange until the rubber seal fits into the flange.
- Return the water supply hose to the fill valve and tighten it using a pair of Channel lock pliers. Turn on the water supply and check for leaks.
