Once all connections are secure, slowly turn the main water supply back on. Go to the faucet and turn on the cold and hot water to bleed any air out of the lines. While the water is running, carefully inspect all the connections behind the tub for any signs of dripping or leaks. Test the faucet's diverter to ensure water flows to the shower head properly. If there are no leaks and everything functions correctly, the installation is complete. Remember to turn the power back on to the water heater if you turned it off.

FAQs
What if my old shower cartridge is really stuck and won't come out, even with pliers?
A cartridge puller tool specifically designed for your faucet brand (e.g., Moen, Delta) is highly recommended for stubborn cartridges. Using the correct tool prevents damage to the valve body, which is a much more complex repair. Applying penetrating oil and letting it sit for a bit can also help loosen corrosion.
Why is shutting off the water supply so crucial, and what happens if I forget?
Shutting off the water supply, either at the main or the specific shower valve, is the most critical safety step to prevent flooding. Forgetting this will result in a high-pressure stream of water when you remove the cartridge, potentially causing significant water damage and a very messy situation. Always double-check by briefly turning on another faucet after shutting off the main supply.
Is the estimated 2-hour time frame realistic for someone with no DIY experience?
The 2-hour estimate is achievable for someone with basic DIY skills and the right tools readily available. For a complete beginner, it's wise to budget 3-4 hours, especially if you encounter stubborn parts, need to read instructions carefully, or have to make a trip to the store for a specific tool. Take your time to avoid mistakes.
Do I need a special 'cartridge puller' tool, or can I just use regular pliers for extraction?
While some cartridges might come out with regular pliers, many, especially older or corroded ones, require a specialized cartridge puller tool. This tool grips the cartridge more effectively and minimizes the risk of breaking internal plastic components or damaging the valve body, which would lead to a much more expensive repair. It's a worthwhile investment if your cartridge is stuck.
