A faulty toilet flush valve disturbs the integrity of your toilet as far as the sanitation is concerned. Such issues must be fixed immediately in order to restore the serenity of your plumbing setup.
Before you look to replace the faulty flush valve with a new one, try diagnosing the flaw in the valve and evaluate if it can be fixed. If the fault seems to be irreparable then move to the replacement job of the flush valve.
Also arrange all the plumbing tools that would play a pivotal role in the success of the project. These tools include the wrenches, pliers, screwdrivers, Teflon tape etc. Once all the tools are arranged, turn off the water supply valve which is located below the tank.
Next, open the lid of the tank and empty it by either flushing down the water or removing it with a small container. If still some water is left in the tank then clean it out using a piece of cloth. Now start dissociating the valve chain that is attached to a trip arm in the underlying setup.
Now move to the actual task of detaching the old or broken flush valve from the toilet fixture. Simply lift the valve or the flapper from the flush valve seat by detaching the clips (on the side) from the overflow tube. The method of detachment of the flush valve varies depending on the type of flush valve you're using. Once the flush valve is completely detached from the setup, make way for a new flush valve. Make sure that the new flush valve is similar to the old one in terms of the flapper style and the adjoining clips.
Place the new flush valve on the flush valve seat and bind the clips to the fixture on both sides of the overflow tube. Once clipped, check the flapper to make sure it rests flat on the flush valve seat.
Clip the valve chain back to the trip arm in such a way that the flush flapper makes a good seal with the flush valve seat.
Test the success of the project by rendering normal water supply to the toilet and flushing the water down.
