Installing or replacing a kitchen faucet is easy to do, even for a novice do-it-yourselfer. The most difficult part of the installation process is removing the old faucets. Once that is done, it really is a piece of cake, because you won’t need any specialized tools or soldering to complete installation. Before you begin, make sure the new faucet is a match for your sink by verifying the number of holes and centre-to-centre distance. An hour or two later, your sink should be operational again.

Before Assembly


Verify the number of holes on the sink before you choose a faucet. A standard sink will have between one and four holes. Faucets require one to three holes depending on the model. Even if it is possible to drill the sink in order to add new accessories, such as soap dispenser, it is preferable to replace the sink because of the difficulty in drilling certain materials.
Measure the center-to-center distance separating the two mounting holes at the back of the sink. The center-to-center distance must be the same for the new faucet. Since these are standard measurements, the distance should be either 4” or 8”.


Be sure to wear safety glasses when you’re working under the sink.
Turn off the water supply using the valves under the sink. If you don’t have shutoff valves, shut off the water main, usually located in the basement. Drain the pipes and collect the water by opening the siphon under the sink.
If you are also replacing the sink, it is much simpler to install the faucet before you install the sink, then you’ll just have to make the connections.
