Understanding Delta Cartridge Types

To get your Delta faucet working properly again, you need to replace the worn or damaged cartridge inside. But with so many types of Delta cartridges, how do you know which one is right for your specific faucet? Let’s break it down.

The most common cartridges are the Delta 1300, 1400, and 1700 series. The 1300 and 1400 are older models, while the 1700 is newer. To determine which series you need, check your faucet for the model number, typically located on a tag under the sink or inside the cabinet. Once you know the series, you can order the correct replacement cartridge.

For single-handle kitchen faucets, the 1300 and 1400 cartridges are compression style, using rubber seals and springs. The 1700 cartridge is a washerless design, using ceramic disks for leak-free, durable performance. If your faucet feels loose or leaks, the cartridge likely needs replacing.

Replacing a cartridge is a straightforward DIY task. Simply turn off the water supply, remove the faucet handle and trim ring or cap, take out the old cartridge, and pop in the new one. Be sure to lubricate the new cartridge and seals to allow for smooth operation. Tighten everything back up, turn the water on, and check for any leaks before using your faucet.

With the model number in hand and an understanding of the different types of Delta cartridges, you’ll be able to find and install the correct replacement part to get your kitchen faucet working like new again. Let the water flow!

Locating the Serial Number

To find the right replacement cartridge for your Delta single-handle kitchen faucet, you’ll need to locate the serial number. This unique code identifies your specific faucet model, so you can purchase the correct part.

Finding the Serial Number

The serial number for your Delta faucet is usually located in one of three places:

    • On the base of the faucet under the sink. You may need to disconnect the water supply lines to access it.

    • On the side or back of the faucet above the counter. Check the left or right side of the spout base or the back of the faucet body.

    • On the original packaging or owner’s manual for your faucet. If you still have these, the serial number should be clearly printed on them.

Once you find the serial number, write it down or take a photo of it for reference. You’ll need to provide this number when purchasing a replacement cartridge, either in-store or online. Having the correct serial number helps ensure you get a cartridge that properly fits your faucet model for optimal performance and to avoid leaks or other issues.

Some Delta faucets also have the model number printed on them, which can be an alternate way to identify the correct replacement part. However, the serial number is the most accurate means and the one Delta recommends using.

When shopping for a new cartridge, check that the packaging specifically lists your faucet’s serial number or model number to make sure it’s the right replacement. You should also consider the faucet’s age to determine if an upgraded cartridge may provide improved performance or water efficiency. With the right cartridge in hand, you’ll be ready to complete the replacement and have your Delta faucet working like new again.

Installing the New Cartridge

Now that you have the new cartridge in hand, it’s time to install it. This shouldn’t take more than about 15 minutes if you follow these steps:

Shut Off the Water Supply

The first thing you’ll want to do is turn off the water supply to your kitchen faucet. Locate the shutoff valves under or near the sink and turn them clockwise to close them. This will prevent water from flowing out when you remove the old cartridge.

Remove the Old Cartridge

Next, you’ll remove your old faucet cartridge. This may involve unscrewing a retaining clip or cartridge nut to free the cartridge. Gently pry out the old cartridge with pliers. Be very careful not to damage the faucet body. Clean the area where the cartridge sits before installing the new one.

Lubricate the New Cartridge

Apply a little plumber’s grease, petroleum jelly, or silicone lubricant to the o-rings and seals on your new cartridge. This will help it slide into place more easily and create a water-tight seal. Wipe away any excess lubricant with a rag.

Install the New Cartridge

Now you can install your new Delta faucet cartridge. Slide it into place, making sure the hot and cold indicators on the cartridge match your faucet handles. Hand-tighten the retaining clip to hold it in place.

Turn the Water Back On

Turn the water supply back on and check that your new cartridge is functioning properly and there are no leaks before using your faucet. Tighten or loosen the cartridge as needed.
