A faucet or a tap is equipment that regulates the flow of hot and cold liquids from pipes, baths, basins and sinks. A faucet is faulty when after turning off the knob, the faucet still drips water. The common issues associated with faulty faucets include leak, noise and even broken handle but we will be looking at how to deal with a leaky (central, swiveling) basin faucet, which can be as a result of a worn out washer or a broken seat.
Sometimes you will be required to change the faucet altogether but before you do that, let us highlight tips on how to repair a leaky faucet. SOme of these tool will be needed for a neat work: adjustable wrench, screwdriver, penetrating oil, replacement washer and O-ring of same size as the one in your faucet. Follow these step-by-step procedures to repair your faulty faucet:
1. Turn off the water supply to your faucet: Look around your bathroom and underneath the sink to trace the supply line to your faucet, shut off the valve connected to this line. If your house does not have valves connected to individual fixtures, then you have to cut water supply to your house entirely by shutting off the main.
2. Remove the faucet handle: Pull out the decorative part on top of the faucet to expose the screw under it, this screw holds the knob to the stem. Use a screwdriver to unscrew it and gently remove the handle.
3. Loose the packing nut: Using your wrench, loose the nut as well as the stem on top of the O-ring and on top of a seat washer (which is thicker). Inspect them for damage. Usually the washer which is made of rubber can get worn out and in most times the cause of a dripping faucet.
4. Replace the damaged parts: We would advise after removing the washer and O-ring from the faucet, take them to your hardware store as sample to ensure you buy the right size that will fit in. Replace the old one with the new one. You may need to coat the new one with plumber’s lubricant before installing.
5. Reassemble the parts: Carefully put back all parts into place starting with washer and O-ring, stem, nut, screw and then the handle/knob.
Turn the knob on to know if you have successfully repaired the faulty faucet. If the dripping continues after all these, then you have to contact a professional plumber.
