With the trim removed, unscrew the large bonnet nut that holds the cartridge in place. It can often be unscrewed by hand. If it's stuck, you may need channel-lock pliers, but be careful not to damage it. Once the nut is off, firmly grip the old cartridge and pull it straight out. If it is stuck due to mineral buildup, you may need to gently pry it loose with a screwdriver, working around the edges. After removal, use a rag to wipe out any debris or sediment from inside the valve body.
Goal: Remove the faulty cartridge
- Have a bucket or towel ready to catch any residual water that drains from the valve when the cartridge is removed.
- Be gentle when prying out a stuck cartridge to avoid scratching the interior of the brass valve, which could cause leaks.

FAQs
Do I really need a special cartridge puller tool for this Delta shower cartridge replacement?
While not always mandatory, a Delta cartridge puller tool can be invaluable, especially if the old cartridge is stuck due to mineral buildup. You might get by with needle-nose pliers and a a flathead screwdriver if it's not too stubborn, but having the puller prevents frustration and potential damage to the valve body.
The project says 'beginner' and '2 hours.' Is this accurate for a first-timer, and what's the typical cost of a new Delta cartridge?
Yes, this project is generally beginner-friendly, but a first-timer might take closer to 2-3 hours, especially if the old cartridge is difficult to remove. A new Delta cartridge typically costs $20-$50, depending on the specific model and where you purchase it.
What should I do if the old Delta cartridge is stuck and won't come out after removing the retaining clip?
A stuck cartridge is a common issue, often due to mineral deposits. Ensure you've removed the retaining clip. If it's still stuck, firmly but gently twist with needle-nose pliers, or use a dedicated Delta cartridge puller tool which provides better leverage. You can also try applying penetrating oil around the cartridge base and letting it sit for a few minutes before trying again.
How do I make sure I buy the correct Delta replacement cartridge for my specific shower?
Delta manufactures several cartridge models. The best way to ensure you buy the correct one is to remove your old cartridge first and take it to the store for comparison. Alternatively, check your shower trim for a model number or consult Delta's website with photos of your existing faucet to identify the part number.
