Diagnosing Moen Cartridge That Won't Go All The Way In
A Moen cartridge is used in the shower to allow proper flow and control the amount of water. It enables you to adjust the water pressure by twisting its handle.
However, the Moen cartridge may sometimes fail to fit correctly. Here are some reasons why that can happen.
If the pipe is too narrow, the Moen cartridge will fail to go all the way in. So, it's best to measure a new cartridge fitting from the base to its tip to ensure it's the right size for your plumbing. Alternatively, you can ask a plumber to customize the pipe size to suit the fitting.
It's also possible that the pipe is a bit wider, causing the cartridge not to fit perfectly. In that case, you can add a rubber grommet or the "O-ring" to the cartridge to tighten its bond with the water pipe.
See this cartridge repair kit on Amazon.
Follow the steps below to tighten a loose fitting:
- Find a rubber grommet the same size as the cartridge.
- Wipe the cartridge with a dry cloth.
- Stretch the rubber grommet to fit it in the cartridge.
- Slowly push the cartridge inside the pipe while twisting for proper alignment.
- Test the cartridge to see if the water will flow without leaking. You can opt to seal its surrounding with silicon caulk.
Another reason is that the water pipe gets blocked by small objects like debris or dirt. To resolve this, remove the Moen cartridge and clean its surroundings, or detach the pipe to unclog it manually.
Rust can also cause blockages, especially if the water pipe is quite old. You can use a rust-cleaning solution to eliminate the blockage.
See this rust cleaner on Amazon.
Follow these steps to remove the rust:
- Put the Moen cartridge in a basin with water.
- Wear gloves, then pour some rust-cleaning solution. You may also refer to the product usage instruction.
- Use a small brush to scrub the rust off.
- Rinse the Moen cartridge with clean water, then rub it with a dry cloth.
- Fit the Moen cartridge back into the pipe.
High Water Pressure
The water pressure in the shower's water piping system can go high due to a broken pressure regulator in the main water supply. Consequently, some components, like cartridges, can become loose.
You can adjust the water pressure by turning the shut-off valve clockwise.
The Moen Cartridge Is Too Old
You'll want to consider replacing your Moen cartridge if it's too old. Although you may not see rust around it, its durability can weaken over the years of regular use.
Check the steps for removing and installing a new Moen cartridge below:
- Find a new Moen cartridge of the same size and model.
- Turn off the water supply.
- Twist and pull the handle to remove it.
- Use a chisel to remove the rubber covering, then unscrew the metal plate.
- Pull the remaining parts out.
- Scrape off and clean the surrounding where you removed the metal plate to correct the alignment of the metal plate when you put it back.
- Use pliers to remove the pin on top of the cartridge, then remove the protective ring.
- Insert the plastic nut into the cartridge and twist it.
- Pull the cartridge out.
- Insert the new cartridge and put the plastic nut to lock it in place.
- Reinsert the small pin on top of the cartridge.
- Put back the nuts and other small parts you previously removed.
- Mount and screw the metal plate.
- Insert the rubber knob back into place, then screw and put back the remaining materials according to the order you removed them.

How Much Does It Cost To Replace A Shower Cartridge?
Depending on the contractor, you may spend from $100 to around $500 to replace shower cartridges. Other factors, such as the shower cartridge type, can also affect the cost. Additionally, the difficulty in accessing the shower pipes can cause the price to go higher.
However, the replacement of products due to manufacturing defects is free of charge. You just need to provide proof of purchase and other supporting documents.
How Long Does A Moen Cartridge Warranty Last?
Moen offers a Limited Lifetime Warranty that covers faulty quality and factory defects for the original purchaser of Moen products. So, the homeowner can expect a leak-and drip-free faucet for as long as they use the Moen cartridge.
If the product malfunctions, the homeowner can expect a free replacement of parts to restore proper functionality.
On the other hand, products bought for commercial and industrial use have a 5-year warranty. However, consider reading the full warranty details, as the warranty coverage can differ based on the state or province.
