While 3 hours is a good estimate for an experienced DIYer, beginners should budget more time, perhaps 4-6 hours. Unexpected challenges like rusted connections, stripped screws, limited access, or needing to retrieve forgotten tools can significantly extend the process. Patience is key, as rushing can lead to mistakes.

Always turn off the main water supply to your home and fully drain the lines by opening a lower-level faucet before beginning to prevent flooding.
