A faucet with handles may have a cartridge or disc valve, but in the event that you can turn the handle via more than 90 degrees, it probably includes a compression valve. That’s the first screwable valve with a threaded stem that predates all other types. When you need to turn the handle too many times to close off the water, it’s because the washer at the end of the valve stem is worn out. You won’t have to call a contractor to repair it — it’s an inexpensive part, and replacing it’s a simple task.
Close the water to the faucet. If the faucet is on a sink, then turn off the tighten valve under the sink. If it’s outside, close the main water heater to your home.
Unscrew the handle with a Phillips screwdriver and then pull it off. If the screw is stuck, then spray it with lubricant to avoid stripping the mind with the screwdriver.
Loosen the valve retaining nut situated just beneath the handle with a set of pliers. Then unscrew it together with your fingers and remove it.
Lift the valve stem out of the faucet by gripping the end with the pliers and pulling straight up. If it’s stuck, then reattach the handle and use it to pull it out.
Turn the valve stem over and unscrew the washer on the finish with a Phillips screwdriver. Replace it with a new one and tighten the screw to hold it.
Drop the valve back in the faucet, screw to the retaining nut and then tighten it with pliers. Replace the handle and then turn to the water.
