How to Repair a Toilet Shut Off Valve How to Repair a Toilet Shut Off Valve If you are wondering how to repair a toilet shut off valve, the following information can prove very handy. The toilet shut-off valve is also called the stop valve. This is the valve controlling water to the toilet, usually located below the cistern of the toilet. Most shut-off valves are rather durable and only need a replacement after many years. However, due to sustained usage, the valve can malfunction, leading to leaks or reduced water pressure. You don’t need to hire professional help for repairing shut-off valves. These valves have a very basic configuration and they can be easily repaired at home, using some basic supplies. Step 1—Executing Basic Shut off Valve Repair Get started by shutting-off the valve. Shut-off the main water supply to the house to prevent sudden bursts of water. Cover the jaws of the pliers with masking tape. This is critical to prevent scratching of the shut-off valve surface.

Use the pliers to firmly grip the packing nut. This nut is located under the handle of the valve. Turn the nut in the clockwise direction. This is the most basic repair to ensure that the nut is properly tightened. If this doesn’t stop the leakage, proceed by loosening the packing nut by turning the nut in the counterclockwise direction with a plier or wrench. Step 2—Cleaning/Replacing Shut off Valve Washers When loosening the packing nut, make sure to disengage the valve slowly. This creates a time lag of few seconds, helping to increase the pressure in the small amount of water retained around the valve. As a result, the water shoots out of the valve, helping to unclog any debris in the valve. Removing the nut gives access to the threaded valve stem that contains the washers. Use a flat headed screwdriver for edging out the washers. Clean the washers using water and an old toothbrush. Ensure that you remove the mineral deposition that often coats the washers. However, if the washers seem cracked, you need to replace them.

For this, you need to carry the valve stem to a hardware store to procure an exact replacement. Replace the cleaned/replacement washer and secure the valve stem and packing nut. Turn-on the water supply and inspect for leaks. If the leakage persists, proceed in the following manner.

Use a dry cloth to wipe the piping. Using Teflon taping, wrap the pipe threads of water line. Make at least two complete turns of the Teflon tape over the pipe threads for ensuring better fitting. Use a scissor to cut the tape. Smooth the taped pipe ending with your fingers. Place the taped piping into its slot and tighten the shut-off valve.

The following will detail how to drain your toilet tank without shutting off the water to the entire home. Look for a faucet/tap on the pipe that leads to your toilet cistern/tank. If you have an older system (pre-1970s) your toilet may not have a shut-off valve. Try slipping a narrow length of wood under the lift arm/float lever (3) and straddling the board across the tank (front to back) to hold the lever up.

Flush the toilet to empty it. After the completion of your repair work, simply remove the board and or strapping to allow the float to refill the tank. If the water supply valve under the tank is all crusty or there is a lot of rust, you shouldn't turn the valve unless you are prepared to replace the valve. An old supply line shut-off will often leak if it has not been used in many years. To attempt adjusting an older valve, it would be advisable to first wrap the valve in cloth and grip it firmly with a heavy pipe wrench, to prevent the valve from twisting the water lines while forcing the tap in or out. Trying to force an older valve open or closed, can easily unseat the fittings of the connecting water lines, thus causing leaks. If repair work is required inside the tank, it might be a good time to consider also replacing the supply valve. Carefully inspect the condition of the water supply valve which allows water to fill the toilet tank (shown by a red arrow in the photo).

This is usually a 90 degree angle valve. Overtime due to minimal use, this valve can become very stiff and brittle. Forcing it closed, and then fully open again can cause weeping, leaks, and breakage. Another common problem with adjusting this valve is noise. An older valve can squeal, rattle and vibrate as pressurized water moves through an improperly seated valve with worn parts. This can occur every time you flush. This method will only help with minor repairs inside the tank. Any major plumbing should be undertaken with the water supply completely turned off.The plumbing supply shutoff valves behind toilets or under sinks can go for years without being turned off and then reopened again. That inactivity can cause the neoprene washers to become either brittle or crusted up with mineral deposits, and they lose their ability to seal leaks. Occasionally, after shutting off a toilet supply valve to replace the tank plumbing parts, you may find that the shutoff valve leaks through the packing nut once the valve is opened again.
