Toilet Valve Replacement: Installing a New Flush
A faulty toilet valve is a common problem which often leads to leaks. When your toilet is leaking or not flushing properly, the most likely culprit is a flush valve that will need to be replaced. This handy step by step guide will walk you through the process of installing a new flush valve in your toilet.
Step 1 - Shut Off Water to Toilet
Locate the water inlet hose and valve which should be located directly beneath the water tank of your toilet. Turn the valve clockwise to tighten it. Tighten the valve all the way until the water flow into your toilet stops.
Step 2 - Remove the Toilet Tank Cover
Remove the toilet tank cover from your toilet and set it aside.
Step 3 - Flush the Toilet
Place an empty bucket beneath the tank of your toilet. Then, attempt to flush the toilet if possible. If you cannot use the handle to flush the toilet, reach inside the tank and lift the flapper located at the base of the tank. Do this until all the water drains out of the toilet tank. The empty bucket will be used to catch any water that spills out because of the faulty valve.
Step 4 - Remove Toilet Tank
Take an appropriate sized wrench and remove the two nuts on the bottom of the toilet tank. Once you remove the nuts, you should be able to simply lift the tank off the toilet bowl. Next, place the toilet tank upside side down so that you can work on the bottom of it.
Step 5 - Remove Flush Valve
On the bottom of the toilet tank, you should notice a large nut and seal that hold the flush valve assembly in place. Take a large wrench and turn the nut counterclockwise to loosen it. Remove the nuts and turn the tank over to remove the old flush valve.
Step 6 - Install New Flush Valve
Insert the new flush valve in the opening at the bottom of the tank. Then, place the news seal and nut on the bottom of the toilet tank and turn the nut clockwise to tighten it.
Step 7 - Replace Toilet Tank
Position the tank back on the toilet bowl and replace the nuts you removed earlier. Be sure to tighten the nuts completely to secure the tank to the toilet bowl. Also, make sure that the chain and flash valve handle are connected to the new flush valve assembly.
Step 8 - Replace Tank Cover
Carefully put the tank cover back on to the toilet tank.
Step 9 - Turn On the Water
Turn the water inlet valve counterclockwise to loosen it and open the water supply to the toilet. Once the toilet tank fills with water, test the new flush valve to make sure that the toilet flushes properly and that there are no more leaks underneath the toilet tank. Then, remove the bucket and use your old towel or rag to wipe up any water that may have spilled in the area.
