What Causes A Leaky Faucet?

As there are different types of faucets, the solutions for each of the faucet leaks are different. The leaks are caused by multiple reasons in these faucets. I have provided the step-by-step solution below with the causes. So, please have a look at it :

Cartridge faucet

Cartridge faucets usually leak because of water and damaged parts. There is a seat that is placed on the top of the cartridge which forms a watertight seal. These seats can become worse due to their constant overuse. Also, the parts won’t fit properly if they get old. As a result, the water starts leaking through the faucet.

Another reason for the faucet leak is the water itself. The base of the cartridge is made of ceramic, brass, or metal. When the corrosive water flows through the brass of the cartridge, the cartridge starts wearing out. As a result, the faucet leaked.

Cartridge faucet


Step 1: At first, stop the water supply

Step 2: Now take off the handle by removing the screws

Step 3: Once you get access to the cartridge, take it off by removing the retaining nuts with the help of a puller

Step 4: Now you will see worn-out o-rings and seals. Remove the damaged parts

Step 5: Place new o-ring and seals into the place

Step 6: Replace everything in order

Compression faucet

The compression faucet often wears out due to the washer in the faucet. And the work of the washer is to stop the water flow. When you tighten the washer, the valve seat stops the water flow. This washer can get worse over time. And a bad washer cannot stop the water flow. As a result, the faucet starts leaking.

Compression faucet


Step 1: Turn the shut-off valve on the water line counterclockwise and stop the water supply

Step 2: Now pry off the decorative cap

Step 3: Now loosen the screws and release the handle from the valve stem

Step 4: Take off the valve assembly cover

Step 5: Make the washer apart from the valve seat

Step 6: Now you will require a faucet repairment kit to replace the washer

Step 7: Once you have placed it in position, secure it with the brass screw

Step 8: Now put back the valve assembly on place

Step 9: Put back everything you took off in order

Step 10: Start the water supply

Ceramic disk faucet

The ceramic disk faucet often leaks due to the rubber seals. And the corrosive water can damage these rubber seals and clog them up. Also, over time, the rubber seals get bad. It fails to stop the water flow and leads the faucet to start leaking.

Ceramic disk faucet


Step 1: Shut off the water supply

Step 2: Remove the handle

Step 3: Elevate the disk to examine the seals

Step 4: If you notice, there are bad or worn-out rubber seals, remove them

Step 5: Place new rubber seals

Step 6: Now put back the disk by tightening the nuts

Step 7: Replace what you took off in order

Please note, if the disk system is completely worn out, there is no chance to repair it. In that case, you need to replace the disk assembly as well.

Ball-type faucet

The ball-type faucet can get worse due to multiple reasons. And the rubber seals and O-rings can dry out over time. As they wear out, it becomes impossible to stop the flow of water. Sometimes, the ball can also crack. These problems will eventually cause the faucet to leak.

Ball-type faucet


Step 1: Turn off the water supply and take off the handle

Step 2: If it is a plastic handle, you need to remove the decorative cap first. Then remove the screws that are holding the handle

Step 3: Now you need to tighten the retaining ring which you will find below the handle

Step 4: It will most likely stop the leak, but if it doesn’t, you need to untighten the ring and remove it again

Step 5: Now check if the balls and springs are worn out

Step 6: Replace the worn-out balls and springs

Step 7: Remove the gasket and place a new gasket there

Step 8: Replace the O-ring

Step 9: Apply the plumber’s grease on the o-ring. It will help the ball to seat properly

Step 10: Now replace everything in order
