NPT Magnesium Anode Rod 3/4 Inch 21 x 300 mm, Anti-Corrosion Protection for Water Heaters, Sacrificial Anode for Hot Water Tank, Extended Lifespan, Suitable for Motorhomes

Anode for water heater: Anodes are also called anode rods. Their main component is magnesium; the anodes are made from an environmentally friendly, durable and high quality magnesium alloy to ensure they stand the test of time. Scope of application: anode rods are suitable for RV water heaters. Magnesium anode rods extend the life of the water tank by absorbing impurities from hot water. Anode rods should be replaced regularly and spare parts should be kept handy in the camper. Water Heater Protection The magnesium rod is located inside the tank of the water heater, in direct contact with the tank (mainly iron) and water. Due to chemical principles, the formation of an electrochemical cell prevents the generation of impurities. High quality: When the water temperature exceeds 40 °C, impurities form inside the water heater. The combination of magnesium rod and iron protects the inner tank from damage.
