What materials are needed for faucet installation?
Each faucet installation requires five materials: the faucet itself (single-handle, double-handle, pull-down, or touchless — ensure it matches your sink's hole configuration), supply lines (braided stainless steel flexible connectors in 3/8" compression fitting, sold in pairs), a P-trap assembly (the curved pipe under the sink that prevents sewer gas from entering the home), plumber's putty or silicone sealant (creates a watertight seal between the faucet base and the sink surface), and teflon tape (wraps threaded connections to prevent leaks). You may also need new shutoff valves ($8-$25 each) if the existing ones are old or stuck, and a basin wrench ($12-$20) to reach mounting nuts in tight spaces under the sink.
How do you choose the right faucet for your sink?
Three things to verify before buying a faucet: First, hole count and spacing — kitchen sinks have 1-4 holes; the faucet must match. A single-hole faucet needs 1 hole (plus optional deck plate to cover extras). A widespread bathroom faucet needs 3 holes at 8" spacing. Second, connection size — most residential faucets use 3/8" compression fittings, but some commercial-style faucets use 1/2". Third, the supply valve type under the sink — compression valves, ball valves, or gate valves each require compatible supply lines. Getting any of these wrong means a return trip to the store. Take a photo under the sink before shopping.
What are common faucet installation mistakes?
Five costly mistakes contractors and DIYers make: First, not turning off the water supply before starting (obvious but happens more than you'd think — the shutoff is usually under the sink or at the main). Second, overtightening supply line connections — hand-tight plus a quarter turn is usually sufficient; overtightening cracks brass fittings and causes leaks. Third, forgetting to remove the aerator screen before flushing the new faucet — debris from installation can permanently clog the aerator. Fourth, using plumber's putty on granite or marble sinks — it stains natural stone; use silicone instead. Fifth, reusing old supply lines to save $8-$25 — the cost of water damage from a failed line far exceeds the savings.
