How to Replace a Leaky Shower Cartridge (Delta Monitor & Moen Models) · Step 6 of 6
In this video
Slide the cleaned cartridge back into the valve body, ensuring it is seated correctly. Hand-tighten the bonnet nut and then use channel-lock pliers to give it a final snug turn. Use a screwdriver to open the stop valves, restoring water flow. Turn on the shower and let it run for approximately 15 minutes. During this time, check that the water temperature remains constant and inspect the area around the valve inside the wall for any signs of leaks.
Goal: Verify the repair and check for leaks
- Do not overtighten the bonnet nut, as this can damage the cartridge or the valve body. Snug is sufficient.

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.
