Faucet installation is more than tightening a fixture to the sink. The faucet style, hole pattern, shutoff valves, supply connections, sink or countertop condition, and access below the fixture all affect the work.
What to Check Before Buying
Before choosing a faucet, count the existing holes and measure the spacing when multiple holes are present. Confirm whether the new faucet includes a deck plate, pull-out hose, side sprayer, soap dispenser, or separate control. A faucet designed for a different configuration may require an adapter or may not fit cleanly.
What Installation Involves
A provider may inspect shutoff valves, supply lines, the mounting surface, drain clearance, and the condition of the cabinet or countertop. Corroded valves can make removal difficult, and a weak mounting surface may allow movement or leakage. The water may need to be shut off for the fixture and, if necessary, at the main supply.
Repair or Replace
A leaking faucet can sometimes be repaired with a cartridge, washer, valve, or aerator, depending on its design. Replacement may be more practical when the body is corroded, parts are unavailable, the finish is failing, or the fixture has leaked long enough to damage the surrounding surface. Repair and replacement are different decisions from installation alone.
Features and Compatibility
Pull-down and pull-out faucets need enough hose clearance below the sink. Touch or motion models may need batteries or an electrical connection. A filtered-water tap or instant-hot feature may require additional connections. Discuss these details before work begins rather than discovering that the cabinet cannot accommodate them.
Preparing for Installation
Remove stored items from beneath the sink and have the faucet instructions and parts available. Avoid using a shutoff valve that is visibly corroded or difficult to turn. Mention any history of leaks, low pressure, cabinet swelling, or water damage.
What to Confirm
Ask how the old faucet will be removed, whether deteriorated valves or supply lines may need attention, and how the new fixture will be tested. The completed work should be checked for leaks with the faucet running and the cabinet area dry enough to reveal seepage.
