In this video
Before starting work on the plumbing, locate and shut off the main water supply to the house. To minimize water spillage when you remove the old valve, open a faucet at the lowest point of the dwelling, such as a basement laundry tub or an outdoor spigot, to drain as much water as possible from the pipes. Once the water is off and the lines are drained, you can proceed with removing the old valve and supply line.
Goal: Prepare Plumbing System for Work
- Before removing the existing valve, shut off the main water supply.
- If possible, open a faucet at the lowest point of the dwelling... this will relieve excess water in the system and reduce the amount of water that will escape.

FAQs
How do I ensure I've completely turned off the water before starting, especially if the shut-off valves are old or stuck?
Locate the hot and cold shut-off valves under the sink and turn both clockwise until they stop. If they feel stuck or don't fully stop the water flow, you may need to shut off the main water supply to your entire house for safety. Always have a towel ready for any residual drips or leaks.
Do I need any special tools beyond an adjustable wrench to remove or install a faucet, particularly in tight spaces under the sink?
While an adjustable wrench is crucial, a basin wrench is highly recommended for reaching and loosening the mounting nuts that secure the faucet from underneath the sink, especially in cramped areas. A small flashlight or headlamp can also significantly improve visibility. Pliers might also be helpful for stubborn connections.
What should I do if my new faucet leaks immediately after installation and turning the water back on?
Immediately turn the water back off at the supply valves under the sink. Most leaks occur at the supply line connections or where the faucet body meets the sink. Ensure all nuts are hand-tightened, then give them an additional quarter to half-turn with your wrench, being careful not to overtighten. Verify that all washers and O-rings are correctly seated.
Is 3 hours a realistic estimate for a beginner, or are there common issues that could significantly extend the project time?
Three hours is a good estimate for a beginner if the existing setup is relatively clean and accessible. However, severely corroded nuts, rusted supply lines, or very limited working space under the sink can easily double or triple the time needed. Patience and having the right tools on hand are key to managing these challenges.
