Tips For de-Winterizing RV Water Heater


#1. If you removed the water heater plug for the winter, re-wrap it with Teflon tape before inserting it in again.

#2. Clean your water pump and you do this by opening those low point valves and letting the anti-freeze drain out. Flush the system well and turn on your water pump to do this. Before you turn it on making sure to be connected to a water source.

#3. Do not forget to flush your faucets, toilet, and outdoor shower when you de-winterize. If you have a washer, then follow the manufacturer’s instructions to get it ready for spring washing duties.

#4. Do not forget to close the bypass valve if you have one. You do not want water going by the water heater. Also, do not forget to open the hot and cold water valves next to your heater. You will want to fill the tank soon.

#5. Don’t overthink this process. It is a very simple one and does not take a lot of time to get the anti-freeze flushed out of your plumbing system

What Happens If I Get Antifreeze in My RV Water Heater?


Nothing serious will happen if this scenario happens to you. Anti-freeze is not a harsh chemical or a corrosive one so it is perfectly safe for some anti-freeze to be inside your water heater.

The problem comes in if you do not remove the anti-freeze before you start cooking or washing dishes etc. RV anti-freeze is like any other anti-freeze in that you should not drink it.

If some does get into your water heater’s tank do not panic. Just take the extra time needed to flush it out and make sure the tank is clean before adding more water to it.

To flush it out, make sure to open the drain plug and use a hose or wand to clean out the inside of the tank. If your RV is newer, you may have a tankless water heater built in so you may not have to worry about this problem.

Just flush the faucets in your bathroom and kitchen and you should be fine. If you have a bypass valve system, then do not open the cold or hot water valves until you have flushed out the pipes.

How do You Sanitize a Camper Water System After De-Winterizing?


There are different products you can use. Some RV owners use diluted bleach to kill the germs in their plumbing and tanks. Other RV owners will use vinegar and baking soda in separate steps.

The way to use these different products is to fill your freshwater tank with the correct ratio of bleach or vinegar or other chemicals, and run the mixture through your plumbing system.

This will include your water heater tank as that tank can grow bacteria and mold as well. Make sure the mixture stays in your system overnight to get the best results.

The next morning you should drain your plumbing system and then flush it out so that nothing poisonous remains. When your fresh water tank is full, you will want to open up all faucets, both hot and cold, to let that mixture run through your system.

When it comes to the water heater, just do not use chlorine.

Some Final Words

The best times to sanitize your water system will be after it has been sitting for months. Also, if your water heater tank has had standing water in it for a while, you should consider sanitizing it as well.

Sanitizing is important as you never know when germs and bacteria are growing inside your plumbing or water heater. This is not a hard task either. It just takes a little time to get done properly.

You will have peace of mind afterward which is always a good reward.
