Some common reasons you might not be able to turn off your faucet include: Stripped faucet handles. Worn washers in the faucet stem. Worn or broken handle seat.
If the handle is stiff to rotate without the cartridge, then it is possible there may be some build-up within the handle preventing it from rotating smoothly. Try soaking your handle in a 50/50 solution of white vinegar and water for 30-60 minutes to see if this helps clear the build-up.
The most common reason is that spinning faucet handles can be caused by general wear and tear on the faucet stem, otherwise known as the faucet cartridge. This part can be replaced by removing the faucet from the sink and inserting the new cartridge.
Clean or Replace
Clean out the inside of the faucet valve with vinegar, and repeat the cleaning on the cartridge. Inspect for metal shavings, worn parts, grit, or mineral buildup. A scrub brush can help loosen deposits. Use the plumber's grease to lubricate any threads you can see.
To prevent future build up and corrosion, use WD-40 Specialist® Penetrant Spray on your taps once a month to lubricate them, keeping them supple and free from rust.
Some major reasons water might not be dispensing from the hot side of the faucet include; airlock issues, a faulty water heating system, blocked plumbing, valve malfunctions, or pipe blockages.
The most common reasons are worn-out washers, faulty seals, loose handles, clogged aerators, and broken pipes. To determine which is causing your problem, remove the handle from your faucet and check for any signs of wear or damage. If nothing looks out of place or damaged, the cause could be entirely different.
This can be caused by a variety of factors, including sediment or mineral buildup, a faulty valve or diverter, or a clogged aerator. One possibility is that the aerator, which is the small screen located at the end of the faucet, is clogged with debris.
Figuring out why the tap is difficult to turn is the first step. Your valve may be worn out or there could be limescale build up. Either way, the fix is relatively easy. The key is paying attention to the order you take apart the tap, so you can reverse that order when putting back together.
Check all your taps before doing anything else, and see if the problem is centralized to one faucet or spread across your house. If only one faucet is having problems, you may simply be dealing with a clogged aerator. You should also see if the faucet's stopcock is open, as this too may be causing it to shut off.
There are three reasons why your faucet won't turn off:
Your faucet's handle is stripped and needs to be replaced. Your handle's stem needs a new washer. Your handle's seat needs to be replaced.
Some common reasons you might not be able to turn off your faucet include: Stripped faucet handles. Worn washers in the faucet stem. Worn or broken handle seat.
The valve lives inside the cartridge housing. It operates via moving the faucet handle from side to side. This motion allows for varying amounts of hot and cold water to flow through the diamond-embedded disc. They enter and combine inside the ceramic dic and then flow out of the faucet.
