Frequently Asked Questions
What does an anode rod do in an RV water heater?
An anode rod prevents corrosion inside the water heater tank by attracting minerals and particles in the water, sacrificing itself to extend the life of the tank.
How often should I replace my RV water heater anode rod?
It's recommended to inspect your RV anode rod annually and replace it when more than 75% of the rod has corroded. Frequent water heater use or hard water may require more frequent replacement.
What size anode rod do I need for my RV water heater?
Rod size depends on the water heater brand and model. Suburban typically uses a ¾" diameter, while Atwood/Dometic models often use ½". Always check your owner's manual or existing rod size.
Is there a difference between magnesium and aluminum anode rods?
Yes. Magnesium rods offer better protection but may corrode faster in hard water. Aluminum rods are more suitable for high-sediment water and last longer, though less protective.
Can I use a plug with an integrated anode rod?
Yes. Products like the RV hot water heater plug with anode combine a drain plug and sacrificial rod for convenience and space-saving installation.
Do tankless water heaters require anode rods?
Most tankless models, like those from Girard, do not use anode rods because they don’t store water. Always refer to the manufacturer’s maintenance guide for proper care.
What is the cost to replace an RV water heater anode rod?
Most RV water heater anode rods cost between $10 and $25, depending on the material and brand. It’s a small investment to avoid tank failure or costly repairs.
How do I prevent insects from entering my RV water heater?
Install RV insect screen covers like those from Camco or JCJ. These stainless steel mesh covers keep out bugs and debris without blocking ventilation.
