4 Easy Steps to Fix Your Toilet’s Broken Fill Valve

Posted: Jun 18, 2018 at 6:33 am   /   by   /   comments (0)

The work of your toilet’s fill valve is to regulate the flow of water into the tank of the toilet. When broken, the fill valve causes a constant flow of water. The result is constant refill cycles. You can, of course, have a reputable plumber here in Lehi help fix this and any other problem once and for all.

But if you have the determination to do it yourself, follow these steps.

Remove the faulty fill valve

Locate the water supply to the toilet then turn it off. Remove the toilet’s lid, flush the toilet, and put a plastic bucket below the water supply hose. On the bottom of the toilet’s water supply shank is a locking nut. Unscrew this nut and remove the whole valve assembly.

The plastic bucket should be able to catch any water drainage.

Replace the fill valve

Now that you have removed the faulty fill valve, adjust the height of the new valve to the size of the tank. Keep the new fill valve an inch below the edge of the tank. Carefully insert the threaded side of the valve into the tank’s base and lock the nut using your hand.

You may turn the nut around using pliers to create a watertight seal.

Reattach the supply lines

With the new fill valve in place, it’s now time to reattach the supply line to the fill valve shank. Place the refill valve back into the overflow tube. Don’t place the tube below the waterline to avoid constant refilling.

Turn your water back on

Turn the water supply back on so the tank can refill. You may adjust the height of the float valve, so it meets your needs. Finally, replace the lid of the toilet tank.

Faulty fill valves are common in older toilets, and they can cause significant water and money wastage. Fortunately, they are easy to replace, and your toilet should start functioning normally within no time.
