Have you ever found yourself in need of replacing the cartridge in your Delta faucet and didn’t know how? Changing a cartridge is a relatively easy task that can be completed in just a few minutes with the right tools and instructions. In this article, we will provide you with step-by-step instructions on how to change a Delta faucet cartridge, as well as some helpful tips to ensure a successful repair. So, if you’re ready to get started, gather your tools and let’s dive right in!

Before you begin, it is important to gather all of the necessary tools and materials. You will need the following: a Phillips head screwdriver, an Allen wrench, a pair of pliers, and a new Delta faucet cartridge. You may also need a flashlight to help you see inside the faucet. Once you have gathered your tools and materials, you are ready to begin changing the cartridge.

The first step is to shut off the water supply to the faucet. You can do this by turning off the valves under the sink. Once the water is turned off, open the faucet to release any remaining water pressure. Next, use the Phillips head screwdriver to remove the handle from the faucet. Once the handle is removed, you will see the cartridge. Use the Allen wrench to remove the cartridge from the faucet. Be careful not to damage the cartridge when you are removing it. Finally, insert the new cartridge into the faucet and tighten it into place. Reattach the handle and turn on the water supply. Check for leaks and make sure the faucet is working properly.

Identifying the Type of Cartridge

Determining the correct cartridge replacement for your Delta faucet is crucial for a successful repair. There are several types of Delta cartridges, each designed for specific faucet models. Knowing how to identify the type you have will help you purchase the right replacement and avoid compatibility issues.

Single Handle Cartridges

Single handle cartridges are commonly found in faucets with one handle controlling both hot and cold water flow. Here’s a guide to help you identify the type of single handle cartridge in your Delta faucet:

Type 1: Two-pronged Stem – This cartridge has a stem with two prongs that connect to the faucet body. It is usually found in older Delta faucets.
Type 2: Delta Faucet Stem – This cartridge is the most common type used in single handle Delta faucets. It has a unique design with a four-pronged base and a thicker stem.
Type 3: Delta Monitor Cartridge – This cartridge is designed for Delta faucets with a temperature control handle. It has a larger body and a five-pronged base.

Cartridge Type	Description
Type 1: Two-pronged Stem	Older Delta faucets
Type 2: Delta Faucet Stem	Most common in single handle Delta faucets
Type 3: Delta Monitor Cartridge	Delta faucets with temperature control handle

Removing the Handle and Escutcheon

To begin, turn off the water supply valves underneath the sink or behind the faucet. Then, locate the set screw holding the handle in place, typically located on the top or side of the handle. Use a small Allen wrench or hex key to loosen the screw and remove the handle.

Removing the Escutcheon

The escutcheon is the decorative plate surrounding the faucet base. To remove it, first remove the handle as described above. Next, locate the screws holding the escutcheon in place. These screws are usually located on the sides or bottom of the escutcheon. Use a screwdriver to loosen the screws and remove the escutcheon.

Identifying the Cartridge Type

Once the handle and escutcheon are removed, you will need to identify the type of cartridge used in your Delta faucet. There are two common types of Delta cartridges: single-handle and two-handle.

Single-handle cartridges are typically identified by a single, large handle that controls both water flow and temperature. Two-handle cartridges are identified by two separate handles, one for hot water and one for cold water.

Refer to the table below to identify the type of cartridge used in your Delta faucet:

Cartridge Type	Handle Type
Single-Handle	Single, large handle
Two-Handle	Two separate handles for hot and cold water

Turning on the Water Supply

Before beginning any plumbing work, it is crucial to ensure that the water supply to the faucet is turned off. This will prevent any water from leaking and causing damage or injury. To turn off the water supply, follow these steps:

Locate the water shutoff valves beneath the sink. These valves are typically located on the hot and cold water lines and are usually a handle or knob that can be turned clockwise to shut off the water.
Turn off the water supply by turning the handles or knobs clockwise until they are fully tightened.
Check to make sure that the water is completely turned off by opening the faucet. If water continues to flow, tighten the valves further or contact a plumber.

Once the water supply is turned off, you can proceed with the steps to change the Delta faucet cartridge.
