The water heater tank design on my camper was difficult to drain and rinse.  The drain plug is plastic and located behind the propane line and burner tube.  Even when I did get the drain plug out, the tank would not drain completely because the drain is higher than the bottom of the tank.  This caused bad smells and yucky water no matter how hard I tried to flush the tank.

Lance Water Heater Drain Flush Hose

I purchased a braided steel plumbing supply line like one you would use for a toilet tank or sink faucet.  At the end, I added a valve and an adapter to a garden hose connector.  I simply screwed in the end of the hose, using plumber’s tape into the tank and attached the valve and adapter again, with plumber’s tape.

The flexibility of the hose allows me to fold it over and store it in the water heater’s tank compartment.  It also resists any heat the heater puts out.  I purchased the parts at a hardware store, but you can find them on Amazon or a big box store.

I now have a quick and easy way to drain and flush the tank.  Just make sure you open the pressure relief valve before flushing!

Now the old water doesn’t run down the side of my truck or into the seams around the water heater that can back up into the camper.

It took me 15-minutes to complete this modification and cost me about $25.  In my opinion, the skill level of this modification is easy.
