In this post, I will answer your question of how to fix a leaky kitchen sink.
Kitchen sinks play a vital role in every household; from washing dishes to fetching a cold glass of water to various other tasks. Thus, they are most prone to damage which can result in leaks leading to water wastage.
Are you looking for a quick fix to get rid of a stubborn leak? Or perhaps you just cannot get your hand on a plumber fast enough? Well, carry on reading to find the best solutions to your sink problems!
First of all, you need to determine the cause of the leak. Once you have found the culprit, you can focus on fixing it. For this, you’ll need to plug in a cover on the drain, fill the sink with water and then unplug it. Use a flashlight to identify the source of the leak underneath the sink!
Mentioned below are the various causes of leaks in your kitchen sink and how to solve them.
How To Fix a Leaky Kitchen Sink
The drain in your kitchen sink can leak due to the following reasons:
- Drains are sealed using plumber’s putty to create watertight seals that prevent leaks. As time passes, the putty can dry out which can cause water to leak from the drain. Just take the drain out, apply a fresh coat of plumber’s putty and put it back! This should do the job and keep your sink leak-free for a long period of time!
- Sometimes though, the cause of the leak is an old and corrodes drain that needs to be replaced. Simply replacing the drain will fix your problem permanently!
These leaks are the easiest to spot as you can see water dripping on top of the sink each time you use the faucet! Sometimes though, the leak runs underneath the sink. This leak is a little harder to spot.
Regardless of the cause of the faucet leak, you’ll need to first of all prepare for repairing it. For this, you’ll need to follow the steps given below:
- Locate the water supplying pipes and turn their handle clockwise to shut them off.
- Plug in your drain cover as you don’t want to accidentally lose a washer or screw.
- Next, determine the type of faucet you have.
- The most common type of faucet is the Compression faucet that has two separate screw handles for hot and cold water. The remaining three have a single swiveling arm that swings from hot to cold to alter water temperature.
- Ball faucets have ball bearings. You’ll need to take the faucet apart to identify it.
- Cartridge faucets have cartridges along with decorative caps.
- Ceramic-disk faucets feature a ceramic cylinder.
Once you’ve identified your faucet type, you can now fix the cause of the leak.
i) In case of compression faucets, the most common causes are old washers and O rings.
To fix them, follow these steps:
• Unscrew and remove the hot and cold caps.
• By using a wrench, remove the nut that will be visible once you take off the cap. Once you unscrew it, you will be able to take out the stem that holds the faucet in place.
• You will now be able to see the O ring. Replace it if you have leaky handles instead of a leaky faucet. You can take it out and use it as a reference to get the perfect O ring for your faucet available at any local hardware store.
• If you have a leaky faucet, the cause is a worn-out washer which is slightly thicker than the O ring. The washer is held in place using a brass screw. Remove the screw, take out the washer, and use it as a reference for buying a new one. Once you have your new washer, apply an even coat of plumber’s grease on it and put it back in its place to fix the problem.
By following these steps, you can easily repair your compression faucet!
ii) When it comes to ball faucets, you’ll need a replacement kit that has various items in it along with a few special tools. The kit only costs around $20 and is available at home repair shops.
You can fix it easily by following these steps:
• Unscrew and remove the handle.
• Loosen the faucet cam using the tools available in the kit. Remove it along with the washer and ball.
• Use needle-nose pliers to remove inlet seals and springs. You don’t need to store them as you’ll use the new ones available in the kit.
• Remove the old O rings. Coat the new ones in plumber’s grease and push them into place.
• Use the new springs, valves, and cam washers present in your kit when reassembling your faucet!
This should successfully repair a faulty leak in a ball faucet!
iii) To fix a cartridge faucet, follow the steps given below:
- Unscrew the handle
- Remove the circular retaining clip using pliers
- Pull up the cartridge and remove the faucet spout to locate the O rings.
- Next, cut off the faulty O rings using a knife and install the new ones.
- Then, reassemble the handle to fix your problem!
iv) For a Ceramic-disk Faucet, you’ll need to follow these steps:
- Remove the handle and the metal escutcheon cap that sits beneath it.
- Unscrew the disk cylinder and remove it.
- Now you’ll be able to see lots of neoprene seals on its underside.
- Firstly, dip the cylinder in white vinegar for several hours to clean it.
- Then, replace the work out thinned seals with new ones.
- Finally, put the handle back together and turn the water on slowly so as to not damage the ceramic disk.
A Clogged P Trap
Sometimes, debris can collect in the P trap and clog it which results in a leak. You’ll need to dismantle it, remove the clog and reassemble it to fix the problem.
To do this, follow these steps:
- Unscrew the nuts that attach the P trap to the garbage disposal and wall drain using pliers.
- Remove the clog. You can use a garden hose to clean out the P trap.
- Put it back in place and tighten the nuts to ensure a tight connection!
4) Loose Drain Pipe connections
Press a clean tissue around all the pipes while the water is running to locate which one is leaking. Then, use a wrench to tighten the metal nuts connecting the leaking pipe to the others. This should solve your problem permanently! However, if you have old rusty drainpipes, we recommend replacing them as soon as possible.
