After every RV trip, it’s imperative to drain your water system to prevent musty odors. Here, we’ll detail how to properly drain an RV’s water heater, line drains, pumps and tanks so you can avoid a trip to the RV parts and supplies shop before your next trip.
Start with the water heater. If it has an electric mode, switch it off. Turn the heater’s breaker off so it doesn’t accidentally turn on with an empty tank. Locate the water heater’s outside compartment, remove drain plug, open pressure relief valve, and drain completely. To drain Suburban water heater tanks, remove the anode rod with a 1 -1/16 inch socket (available at RV parts and supplies stores). Inspect the rod every time it’s removed, and replace when 3/4 consumed.
*Warning: To avoid injury, never drain a heater that’s hot and/or under pressure. To relieve pressure, turn off all water going to the RV and open a hot and cold faucet.
Next, locate the low point water line drains: there’s one for hot and one for cold. Open lines and drain water. Locate the drain for the fresh water holding tank and drain water. Now, turn the water pump on momentarily to force out remaining water (don’t let the pump continue running when empty). Close all the drains and you’re good to go.
If you forget to drain the water system and your cabin gets stale-smelling, you don’t necessarily have to take it for RV service in Glendale- you just need to sanitize the water system. Drain old water and close all drains. Mix bleach and water (I cup : 15 gallons) in a one-gallon container and pour into fresh water holding tank. Fill tank with water, turn on water pump, open all faucets and run water until you smell bleach. Close faucets and let sit for 12 hours. Drain system, refill fresh water tank with potable water, open faucets and run water until bleach smell is gone. Repeat the rinsing process if necessary.
