How to Replace a Kitchen or Bath Faucet

The hard part isn't the new faucet — it's the corroded nuts on the old one 18 inches back under the sink.

Common causes

• Corroded mounting nuts on old faucet
• Wrong number of mounting holes for new unit
• Braided supplies too short for the new install height
• No shut-offs under the sink

Step-by-step

1. 01Shut off angle stops and disconnect supply lines with a basin wrench
2. 02Remove mounting nuts — use penetrating oil and a strap wrench if seized
3. 03Set the new faucet with the deck plate or escutcheon
4. 04Reconnect braided supplies and check for drips at full flow

When to call Northbridge

• Angle stops are seized or missing
• Sink deck holes don't match the new faucet
• Old faucet won't budge (galvanized supplies)
• You'd rather not lie under the sink for an hour
