Anode Rod Replacement in Attleboro, MA
A $200–$400 part that can add years to your tank — the best-kept secret in water heater care.
The anode rod is a magnesium or aluminum rod inside your tank that corrodes so the steel tank doesn't have to. Once it's consumed — usually in 3 to 5 years — the tank starts rusting from the inside, and that's when leaks begin. We extract the spent rod and install a fresh one, buying your tank more years of service.
Attleboro's water chemistry makes anode replacement especially worthwhile: aggressive or mineral-heavy water eats rods faster, and many of the area's older heaters have never had the rod changed since installation day. In vintage homes where replacing the whole heater means navigating a narrow bulkhead or 100-year-old stairwell, adding years to the existing tank with a new anode is often the smartest money you can spend.
How We Handle It
- Shut down the heater and relieve pressure, then locate the anode port on the tank top.
- Extract the old rod — even seized ones — and inspect the tank interior condition.
- Install a new magnesium or aluminum-zinc rod sized to your tank (segmented rods for low-clearance basements).
- Refill, test, and record the replacement date so you know when it's due again.
