All Suburban RV Hot Water Systems have an anode rod which absorbs all the corrosive action of hot water. It is located on the bottom of the HWS under the main burner, you simply unscrew this to drain the tank of water. If the rod is mostly eaten away, simply replace it with a new one.
This is a genuine Suburban Anode Rod.
The downside of using a non-genuine anode
- Incorrect thread which will cause damage to your tank
- Wrong alloy composition which will make your tank smell like rotten eggs and also leave a green jelly like compound in the bottom of your tank
- Incorrect length can cause damage to the cold water inlet socket within the tank
Thread Size: 3/4″ NPT
Made from Magnesium
Be sure to check your anode rod every time you drain your Suburban water heater
