FAQs

What specific tools are essential for replacing a Delta Monitor shower faucet?

You'll primarily need a Phillips head screwdriver for trim removal and installation. A crucial specialized tool is an Arcan Hardened 3 in. Gear Puller AS3GP, which is often necessary for removing a stubborn old valve cartridge. Have penetrating oil and silicone grease ready as well.

What's the most important safety precaution I need to take before starting this project?

The most critical step is to completely shut off the water supply to the shower. This can be done at the main house shut-off valve or by turning off individual hot and cold water lines if available. Double-check that no water flows from the shower before proceeding to prevent flooding.

I'm a beginner. How difficult is this project, and how long should I expect it to take?

This project is classified as beginner difficulty, meaning it's manageable for those new to DIY. The estimated time for completion is around 3 hours. However, this can vary depending on the condition of your old faucet and any unexpected issues, so allow some extra time.

What should I do if my old shower cartridge is stuck and won't come out?

A common issue is a stubborn old cartridge. First, try applying penetrating oil around the cartridge base and let it sit for a few minutes to help loosen it. If it still doesn't budge, you will likely need to use a gear puller, such as the Arcan Hardened 3 in. Gear Puller AS3GP, to extract it safely without damaging the valve body.
