What should I do if my water heater is leaking from the top?

Shut off power and water, then call us. A top leak often comes from loose hot/cold supply connections, the T&P valve outlet, or the anode/vent fittings. We handle same-day diagnostics and repairs for all water heater types, and in emergencies we can often dispatch within 1–3 hours. We serve Medway and nearby towns across MetroWest.

Quick steps:

• Turn off electric power at the breaker, or set gas to “pilot.”
• Close the cold-water shutoff valve to the heater.
• Gently dry the top and check which connection is wet.
• Do not cap the T&P valve.
