One of the most frequent causes of leaking faucets, inconsistent water temperature or hard-to-turn handles is a worn faucet cartridge. If you have been searching about how to replace faucet cartridge, we have put together an easy-to-follow, step-by-step DIY guide in a simple, pro way.
Regardless of whether it is a kitchen faucet, bathroom faucet, or a shower faucet, you can do it with a few tools and the correct procedure.
What Is a Faucet Cartridge?
A faucet cartridge is the part of the faucet that regulates water temperature and flow. As the handle turns or moves up and down, it contains the components that control the mixing and flow of hot and cold water.
This component can wear out with minerals, friction, and wear and tear. Failure of this part leads to leaking, drips, or problems with regulating temperature.
It’s always best to replace the cartridge, not repair it, as it is a sealed unit.
Signs You Need to Replace Faucet Cartridge
It’s essential to diagnose the problem before repair.
Generally, a worn-out cartridge will present itself in one of three ways: your faucet may drip even when it’s turned off, it may not turn on easily, or it may fail to switch from hot to cold properly. There may also be inconsistent or low water pressure.
When these symptoms occur, this typically means a cartridge replacement.
Tools Required for Cartridge Replacement
This repair can be performed using common household items. You will need a set of screwdrivers to unscrew the handles, and an adjustable wrench to unscrew the retainer nut. An Allen key is required for some faucets.
The key component is the replacement cartridge, which fits your faucet. A plumber’s grease is needed to aid installation and maintain performance. Other items like a towel or a small container are useful for catching the water that’s already in the faucet.
How to Replace Faucet Cartridge (Step-by-Step Method)
This is a common method that applies to most faucets.
Step 1: Turn Off Water Supply
To begin, turn off the water supply valves under the sink. Again, turn hot and cold water off by turning them clockwise. Then turn the faucet on to allow any pressure or water in the line to flow out.
Step 2: Remove the Faucet Handle
To replace the cartridge, the handle needs to be removed. The tips of handles usually conceals a small screw. With this screw out, lift the handle upwards. If it’s stuck, wiggle it left and right as you lift.
Step 3: Open Cartridge Housing
There is a retaining nut or clip that holds the cartridge in the faucet body. Gently loosen and remove this with an adjustable wrench or pliers. Take care not to damage the neighbouring metal or plastic components.
Step 4: Remove the Old Cartridge
With the housing off, carefully slide out the cartridge. It’s possible the cartridge won’t slide out easily due to mineral deposits, so a small twist and/or light pull may be required.
At this time, it is important to pay attention to the positioning of the cartridge, as the new one should be placed in the same direction.
Step 5: Install the New Cartridge
Carefully insert the new cartridge in the same orientation. Be sure to insert it into the valve body fully.
You can use plumber’s grease to lubricate the O-rings. This will make it easier to operate and extend the cartridge’s lifespan.
Step 6: Reassemble the Faucet
Put the handle, retaining nut and screws back on the faucet. Ensure all components are securely tightened, but not too tight to avoid damage.
Step 7: Test the Faucet
Gradually turn the water back on. Look for leaks and ensure hot and cold water works properly. The handle should have a smooth movement, and there should be no wobble or drip.
How to Replace a Faucet Cartridge Single Handle
One cartridge controls both the temperature and water flow in single-handle faucets. Orientation is critical.
When installing a new single-handle cartridge, be sure to note the direction of removal. This can cause hot and cold water to be reversed.
It may be useful to photograph the cartridge before removing it to ensure the same position when re-installing.
How to Replace Delta Faucet Cartridge
Delta faucets are common and may feature a slightly different type of cartridge to traditional faucets.
When Replacing a Delta cartridge, the first step is to remove the handle and cover. Accessing the inner valve allows you to remove the cartridge, which may require rocking, or a cartridge puller for a tight fit.
When you replace Delta cartridges, make sure you use the right number. Incorrect cartridges may leak or fail to mix water. After inserting the cartridge, check it is aligned and then reassemble the faucet.
How to Replace Shower Faucet Cartridge
Shower faucet cartridges regulate water mixing between the wall-mount valve body. They are positioned further back inside the wall.
First, you will need to turn off the main water supply to the shower as most units don’t have shut-off valves. Next, take out the handle and trim plate to access the valve.
You can then carefully remove the cartridge using either pliers or a cartridge removal tool. The replacement cartridge must be properly oriented with hot and cold water for accurate mixing.
Afterward, put back the trim plate and check the water flow.
How to Replace a Cartridge in a Shower Faucet
In most cases, shower cartridge replacement follows a similar process but requires extra attention to safety and alignment.
After shutting off water supply and removing the handle, the cartridge is accessed through the valve opening. It should be removed straight without twisting too hard to avoid damage.
The new cartridge must be inserted in the same direction as the old one. If installed incorrectly, water temperature may behave opposite to the control handle.
Common Mistakes to Avoid
Common DIY errors can turn a repair into a dismal failure. A typical problem is using the incorrect cartridge model, resulting in leaks or malfunctions.
People also fail to shut off the water before starting a repair. Other issues include users’ attempts to force parts open, which can damage valve parts.
Finally, misalignment of the cartridge is common for single-handle and shower faucets. So one must know how to change shower faucets.
Troubleshooting After Replacement
If the issue persists after a cartridge replacement, problems can be related to installation.
If it is still leaking, it could be due to misalignment of the cartridge or worn O-rings. If the water pressure is weak, the faucet body or aerator may still be clogged.
If the handle is too tight when turned on, the cartridge may not be properly seated, or it may be dry.
Pro Tips for Long-Term Performance
Regular maintenance can help prolong your faucet cartridge. Regularly cleaning the faucet aerator will help avoid mineral buildup.
Be careful not to over-tighten the handles, which can damage the cartridge. Applying plumber’s grease when installing the faucet helps it run smoother.
For hard water conditions, a water filter can help extend the life of the cartridge. In most of the cases user takes professional ahmadc27.sg-host.com/ help.
