The Steps Involved In Cleaning an RV Water Tank

In the event that you find that your tank needs a deep cleaning, please follow these steps below for the best results.

1) Rinse off any visible sediment on the bottom of the tank with water before scrubbing. The easiest way to do this is by filling the tank up about 1/4 to 1/2 full with water and letting it run for about 5 minutes or so before turning off your water pump. This will help loosen up any dirt, grime, etc. without using bleach or other harsh chemicals.

2) Inspect all of your hoses and pipes to be sure that they are securely fastened in place and free of leaks. If you find that there are any leaks present, then tighten them immediately to avoid exposing yourself to harmful chemicals, visit this link.

3) Use a long handled brush, hose and water pressure to remove any dirt or sediment in the tank. Start from the top of the tank and work your way down. Make sure that every part of the inside is scrubbed with a brush or other implement, and once you’ve scrubbed it all, flush the entire tank with clean water to remove the dirt and grime.

4) Fill up your tank completely, then turn on the water pump. Let it run for a few seconds to loosen up anything that’s stuck at the bottom or sides of the tank, then turn off the water pump. Repeat this process a few times to make sure that you got all of the sediment and grime out of the tank. Allow it to sit for about 5 minutes, then repeat the process again until it stays clean when you turn off the water pump.

5) Let the water run for 5 minutes, then turn off the pump. Flush out all of the taps so that they are clear and free of debris.

6) Fill up your tank completely and make sure that there are no leaks present.

7) Turn on all of the taps at the same time, and then turn off all of them right away. Repeat this process a few times to ensure that you are getting all of the air bubbles out.

8) Once you are certain that there are no leaks present, then your tank is completely cleaned and ready for use.

9) Turn on all of the taps and let the water run for a few minutes before using it to ensure that you get rid of all of the chemicals and debris.
