Why won’t the faucet turn off?
This troubleshooting guide is for most Moen faucets experiencing symptoms of continuous flowing of water even though it is in the turn-off position. Follow these steps:
- Shut off all the running water to the faucet by locating the shut-off valve. You may turn off the main water supply if the valve is not a feature on your unit. This should be your primary step before you do anything else. Otherwise, you could end up causing water damage in your home when you disassemble the faucet. Make sure that no water flows from the fixture by switching the faucet on after you shut it off the water.
- After that, you may now start to disassemble the faucet. It is wise to take pictures of your faucet during disassembly so that you can reassemble it correctly once you are finished. Cover the drain to prevent loss of any vital parts of the faucet. You will need those when you reassemble. Then, start to remove the handles.
- You may research the kind and type of sink you have. You can easily find all of this information online and in the manual as well.
- After removing the parts, check the rubber washers, rings, and other parts. If they have wear and tear, they will need to be replaced and could be the main issue causing the leaks.
Continue reading below to pinpoint the cause of your issue. We go over the parts of your faucet and what to look for to determine how to fix it. It is important to respond quickly to a running water problem or a leak.
A faucet that leaks over time can waste a lot of water in just a few minutes, even hours if you allow it to continue. If you follow the steps mentioned above, and it still does not work, your plumbing could have a bigger problem.
Sometimes, many parts need to be repaired or replaced, or the whole faucet itself needs to be replaced with a new one. If this is the case, you may call a professional plumber and allow them to install fixtures that cause the problem.
Leak versus running faucet
While running and leaking faucets are seemingly the same circumstances, they still have differences that you should still consider.
A leaky faucet drips slowly, while a running faucet has a persistent stream of water. If it is a leaking faucet, two things always come to mind: consistent trickle and tenacious drip of water. However, it is not the same with leaking taps as you can have one already, but you may not be aware. This is because they are not that easy to detect.
If you suspect a leak, you may try this easy test:
- Dry sink completely.
- Get a paper towel and place it over the drain.
- Leave it for a few hours.
- If you come back with a wet paper towel, then you should know that your faucet is leaking.
Running faucets have different faulty mechanisms compared to leaking faucets. The handle stem may need a repair and replacement with a new one. These problems are all because of the usual wear and tear due to use over time.
What causes a leaky faucet?
It is tiring to hear the frequent dripping of water. Now, you will learn to find the real culprit for your leaky faucet and how you can easily fix it.
Loose and worn-out O-ring
The cartridge controls the water flow in the faucet spout. This is a small disc attached to the stem screw that holds the handle. It may be worn out and loose. If you are seeing a leak near your sink handles, this is most likely the reason.
Cartridge leaks can also be because the cartridge itself needs to be repaired and replaced. Make sure it matches your current model to avoid possible problems in the future. You can always take this piece to your local hardware store to help find the correct match. A step-by-step explanation of how to repair this is below.
Rusted valve seat
If the leak originates in the spout, then the valve seat could be the issue. The valve connects the spout and the faucet. The strong build-up of water can make the valve seat turn into rust. If you see a worn, rusted valve seat, you will want to replace that part. Avoid this happening in the future by cleaning it regularly.
Another common reason for spout leakage is the washer that stands against the valve seat. Over time, there will be friction between the two parts, which may cause the washer to wear out. Faucet leaks also happen when the washer is not properly installed and if it has the wrong size.
Same with the valve seats, the outlet and the inlet seals may be corroded by water sediment.
When the faucet drips at a particular time of the day, the water pressure may be the reason.
This is common in most circumstances. The ring and nuts can become loose over time, causing the sink to leak. Adjust and tighten the nuts so you may avoid the leaks.
If it comes from the pipes, most likely you have broken pipes or fitting. This is the time to call your professional plumber.
How to replace the cartridge?
If the cartridge is the issue, then try replacing it with a new one. This will typically fix your faucet.
This is not recommended if you are not a “handy” type. Remember that if you remove and install it inappropriately, you will end up damaging the cartridge and the water supply. So, do it at your own risk or call an expert instead.
- Turn off the main water supply. Cover the sink or the drain in case you missed any parts.
- Take apart the pieces of the faucet and look for the cartridge.
- Remove the clip which holds the cartridge. Keep the clip as you will need it later to reassemble the cartridge.
- Usually, pliers can remove old cartridges. If this won’t remove easily, stop and start to look for a professional. Do not force it, as you might damage the pipe.
- Once the old cartridge has been removed, replace it with the new one. Use lubricant if needed.
- You are almost done! Reassemble the faucet and turn on the main water supply. Test the faucet, and it should be working normally now.
