When the hot water in an RV turns rusty, smells off or runs out fast, the fix is often a small part inside the tank, and rv hot water heater parts are the rods, wands and tools that handle that job. The anode rod sits inside the tank and absorbs the corrosive action caused by hot water, so the tank wall lasts longer, while a flush wand rinses the sediment out through the same opening. This guide walks through the parts, the sizes to match and the order to use them, with the kits the listings describe.

The quick answer
The part that wears out is the anode rod, a magnesium or aluminum rod that screws into the tank on a 3/4 inch thread and absorbs the corrosive action caused by hot water. Match the rod length to the tank: the listings here run 9 inches for the Suburban rod (on Amazon) and 9.25 inches for the other 3, all on a 3/4 inch NPT thread. Flush the tank with a wand before fitting a new rod, and swap the rod each year so the tank keeps its protection.
Step 1: Find the anode rod and check its size
The anode rod screws into the side of the tank on a 3/4 inch thread, and the listings here give 2 lengths: 9 inches on the Suburban rod and 9.25 inches on the VANPET, jixsloft and Skoutag rods. Measure the old rod before ordering, since a rod that is too long will not fit. The Suburban rod fits porcelain-lined Suburban tanks, while the VANPET and Skoutag rods list Suburban and Mor-Flo tanks.
Step 2: Flush the tank before fitting the new rod
Flush the tank with a wand while the old rod is out, so sediment and scale leave through the same opening. The VANPET, jixsloft and Skoutag kits each include a flush wand that connects to a garden hose, and the jixsloft and Skoutag wands (on Amazon) add a 1/2 inch quick connect adapter and a 3/4 inch garden hose adapter. The jixsloft wand (on Amazon) runs 13.7 inches long with a curved stainless steel tip, and its nozzle turns 360 degrees. Turn off the water heater, cool the hot water and release the pressure in the tank before opening it.
Step 3: Fit the new rod and the wrench that removes it
Fit the new rod on its 3/4 inch NPT thread, tighten it with the hex wrench the kit includes, then wrap Teflon tape around the top of the anode rod nut. The jixsloft kit includes a double hex wrench socket and a roll of Teflon tape, and the Skoutag kit includes a dual hex wrench removal tool. The Suburban listing is a rod on its own, with no wrench or tape in the box. The RV water heater maintenance guide covers flushing and anode care for the same tanks.

FAQ: power away from the grid
How often should I replace an RV water heater anode rod?
Replace the rod each year, as the jixsloft listing states. The rod absorbs the corrosive action caused by hot water, and a worn rod leaves the tank wall unprotected.
What size anode rod fits a Suburban RV water heater?
The Suburban rod here is 9 inches long with a 3/4 inch thread and fits porcelain-lined Suburban tanks. The VANPET, jixsloft and Skoutag rods are 9.25 inches long with a 3/4 inch NPT thread and list Suburban and Mor-Flo tanks.
Do I need a flush wand to clean an RV water heater tank?
A wand helps: the VANPET, jixsloft and Skoutag kits each include a wand that connects to a garden hose and rinses sediment and scale from the bottom of the tank. The Suburban listing is a rod on its own, so pair it with a wand if the tank needs a flush.
Can I use a magnesium anode rod in soft water?
Yes. The Suburban listing states its magnesium rod is best suited to high pH and soft water environments and fits porcelain-lined tanks.
