How to Repair a Urinal Flush Valve
A urinal flush valve is a component in the toilet tank tht uses a flapper to control the flow of water into the flush. A common problem is the constant leakage of water through the flush valve, which is frustrating and inefficient, both economically and environmentally. If the urinal flush valve in your bathroom needs to get fixed, follow the simple steps below to repair it on your own.
Step 1 – Turn off the Water Supply
Turn off the water supply connected to the tank. Fush out as much water as possible. Remove the lid to check if the tank is completely drained. If there is still water, use a wet/dry vacuum cleaner or a sponge to dry.
Step 2 – Identify the Problem
There are 3 possibilities:
- The flush ball may be aged or coated with deposits.
- The flapper chain might have detached from the flapper valve.
- The flapper valve or ball might have worn out and may not be glued properly.
Identify the problem causing the leakage before moving on to the next step.
Step 3 – Connecting the Chain/ Strap
If the chain or strap connecting to the flapper valve has become detached, hook it back to the holes that open the flapper valve easily. If this was the only problem, your flush is operational again. However, if the problem persists, move on to the steps below.
Step 4 – Remove Old Assembly
Remove the old flush valve and the rest of the hardware by disconnecting the chain or wire from the trip arm. After removing the flapper or flush ball, be careful not to drop anything in the drain valve opening as it could cause serious clogging.
Step 5 – Clean the Flush Valve Seat and Flush Ball
If the flush valve seat is metal, clean it using steel wool or sandpaper. Plastic flush valve seats can be cleaned using a non-scratching scourging ball. If your tank uses a flush ball is a plug, you can clear it of deposits using abrasive paper or fine steel wool. However, if the valve still leaks. it will need replacement.
After cleaning, completely dry the valve seat of all moisture. This can be done using towels or even a hairdryer. Be careful not to expose any spot of the valve to the heat of the dryer for longer periods.
Step 6 – Using the Flusher Fixer Kit
Follow the instructions on the kit to locate the best position for the flusher fixer over the old worn out valve seat. The kits usually contain a sealant ring. Carefully peel off the protective paper from the sealant ring and then place it over the opening of the valve seat.
Step 7 – Position the Flapper and Fill the Tank
Close the plug with a flapper, and attach the chain that runs from the flapper valve to the flush handle. Trim excess chain, if necessary. Turn on the water supply and fill the tank.
