Remove Old Cartridge and Clean Valve — Gather Tools and Supplies
Part of project
How to Replace a Leaky Shower Cartridge (Delta Monitor & Moen Models) · Step 1 of 6
In this video
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
How difficult is it to replace a shower cartridge, and what should I expect for time and cost?
This project is rated as "beginner" and typically takes about 3 hours for someone with basic DIY skills. The main cost will be the replacement cartridge itself, which varies by brand (Delta or Moen) and model, usually ranging from $30-$80.
What specific tools do I absolutely need before I start this project?
You'll definitely need Phillips and flathead screwdrivers, an adjustable wrench, and tongue and groove slip joint pliers. Also, have a rag for drips and plumber's grease for new O-rings. Ensure you have the correct replacement cartridge for your specific faucet model.
What are the most crucial safety precautions I need to take before starting this cartridge replacement?
The most critical step is to completely shut off the main water supply to your house or specifically to the bathroom before starting. After shutting off, open a nearby faucet to relieve any remaining pressure in the lines. Protect your tub/shower finish from dropped tools.
How do I make sure I buy the exact right replacement cartridge for my specific shower?
To ensure you get the correct cartridge, first try to identify your faucet's brand (Delta Monitor or Moen) and model. Often, the old cartridge will have a model number printed on it; take a photo of it. If not, consult your faucet's manual or remove the old cartridge and take it to a plumbing supply store for identification.
