Delta Cartridges: What Are They?
Delta cartridges refer to the internal valve mechanisms used in Delta faucets. They are responsible for controlling the flow and temperature of the water. These essential components regulate water flow and provide smooth operation of the faucet handle.
Depending on the model and design, Delta faucets use different types of cartridges. The following are the three primary types of Delta cartridges commonly used.
- Delta Single-handle Cartridge: This type of cartridge is used in single-handle faucets where a single lever controls both the water flow and temperature. It features a cylindrical shape with various seals, o-rings, and control mechanisms. Often, single-handle cartridges are found in kitchen faucets, bathroom sink faucets, and shower faucets.
- Delta Dual-handle Cartridge: The dual-handle Delta faucets use this type of cartridge, where separate handles control hot and cold water. It consists of two cartridges, one for each handle. Commonly, these faucets can be found in shower faucets, widespread bathroom faucets, and older bathroom sink faucets.
- Delta Pressure Balance Cartridge: In particular, the Delta tub and shower faucets are equipped with such faucets. The pressure balance cartridge can maintain a consistent water temperature even if there are fluctuations in water pressure.
Why Do You Need To Replace Delta Single Handle Kitchen Faucet Cartridges?
There are several reasons why you might need to replace a Delta single-handle kitchen faucet cartridge. Among them, the following reasons are very common.
- Like any mechanical component, a faucet cartridge can wear out over time. Continuous use, exposure to water, and mineral deposits can cause deterioration of the cartridge. In such cases, you should replace the faucet cartridge to ensure proper functionality.

How To Replace Delta Single Handle Kitchen Faucet Cartridges: The Step-By-Step Process
Replacing a Delta single-handle kitchen faucet cartridge is easy. The process involves several steps that I have listed below. Hence, follow each step carefully to replace your Delta single-handle kitchen faucet cartridge in no time.
Step 1: Turn Off the Water Supply
First of all, locate the water supply valves beneath the sink. Then, turn them off by rotating the handles clockwise. This will shut off the water flow to the faucet.
Step 2: Relieve Pressure
Turn on the faucet handle to release any remaining water pressure. This is needed to prevent any potential spraying when you remove the cartridge.
Step 3: Remove the Handle
Usually, a set of screws is located at the base or underneath the handle. Once you find these screws, use a screwdriver to loosen and remove them. Lift the handle off the faucet after removing the set screws.
Step 4: Remove the Bonnet Nut
Using an adjustable wrench, loosen and remove the bonnet nut. Turn it counterclockwise until it is loose enough to remove by hand. The bonnet nut may be tight and require some force to loosen. So, be cautious while removing it.
Step 5: Remove the Cartridge
With the bonnet nut removed, you can now access the cartridge. Grab the cartridge stem with pliers and pull it straight out. If the cartridge is stuck, you may need to gently twist it back and forth while pulling to loosen it. Once the cartridge is free, remove it completely.
Step 6: Install the Replacement Cartridge
Take the replacement cartridge and align it with the opening. Make sure it is inserted in the correct orientation. Push the cartridge straight into the valve body until it is fully seated. While doing this, you may need to apply gentle pressure.
Step 7: Reassemble the Faucet
Reinstall the bonnet nut by hand and then tighten it with an adjustable wrench. However, don’t overtighten, as it may damage the cartridge or the faucet. Place the handle back on the faucet and secure it with the set screw. Use the screwdriver to tighten the set screw.
Step 8: Turn on the Water Supply
In Step 1, you turned off the water supply. Now, it is time to turn it on. By rotating the handles counterclockwise, you will open the water supply valves. This will restore the water flow to the faucet.
Step 9: Test the Faucet
Turn on the faucet and check for any leaks or irregularities in the water flow. Double-check if the cartridge is properly seated or if the bonnet nut is securely tightened. For major issues, consult a professional plumber.
