What Should Be Done to Sanitize The RV Water Tank?

The RV water tank needs to be sanitized. It is a myth that you should only fill the tank with fresh water when you are at home in order to flush out bacteria and parasites. You also want to make sure you use only clean containers, as anything dirty could introduce more bacteria into the water and cause it to spoil faster.

Methods for sanitizing RV water tanks

Sanitizing RV water tanks

Method 01:

Use a jug of fresh water and an empty bucket to rinse out the RV water tank. This will help to flush out any sediment that has built up in the bottom of the tank. Then use a minimum of one gallon per minute from a garden hose for five minutes, spraying all liquid surfaces inside the tank and allowing it to drain.

Method 02:

Add RV Sani-Con tablets into the tank, wait 20 minutes, and then rinse with fresh water. The tablets can be purchased at any RV dealer or retail outlet. The EPA recommends changing the water in your tank every three months, but they also recommend performing a sanitizing procedure twice a year.

Method 03:

Use two cups of household bleach mixed with one gallon of water and wait 15 – 20 minutes before flushing. Always be careful to avoid splashing or spilling the solution on yourself as it can cause serious burns, plus bleach is extremely dangerous if ingested in any amount.

Method 04:

When checking for leaks, always place some soapy water on all surfaces in and around the tank and overnight to see if any water has leaked out. An RV antifreeze leak can do serious damage to your RV, so always be sure you know where to look for leaks before they become a problem.

Method 05:

Take the RV water tank to a service center for annual cleaning and inspection. This will not only make sure that your tank is sanitized but will also ensure that there are no leaks and everything is in good working order. Be cautious though, as some outlets will try to sell you unnecessary repairs if they notice any issues with the system.

RV Water Tanks: Other Things to Consider

RV Water Tanks

Number 01

Insulate the exterior of your RV water tank to prevent it from cooling down too much at night. As well as this, you want to make sure that your engine block is also insulated so that heat doesn't carry through the engine and into the water supply, causing it to freeze inside the lines. Some newer RVs come equipped with built-in heaters so that the water remains at a warm temperature and is much less likely to freeze.

Number 02:

When buying your RV, look for one with an insulated tank as it will carry over into other areas of the vehicle's design as well. An insulated tank utilizes industrial insulation in order to help keep the water warmer longer so that it is less likely to freeze. This will also save you money on heating costs in the long run.

Number 03:

When the tank does finally freeze, you want to be as careful as possible when thawing it out, never use a propane torch or blowtorch to speed up thawing. It won't cause the tank itself to crack, but it could cause your plumbing lines to burst open and flood your RV. A safer method would be to use a hair dryer or space heater on a low heat setting close to the freezing area. Allow it time to thaw naturally rather than risking damage by forcing the issue.

Advantages of RV water tanks

Advantages of RV water tanks

The advantages of RV water tanks can be summarized as follows:

• Water tanks are lightweight and easy to carry around the campsite.

• This particular type of water tank is an affordable option for people who don't want to buy a more expensive one.

• Single-hose RV water tanks are good for those looking for a camping tool that is simple yet functional.

• Single-hose RV water tanks are better alternatives to jerricans, as they do not take up much space and can be held easily.

• These water tanks are relatively more durable than other options available in the market.

• Water tanks are easy to store and carry around without causing any hassle.

• This option is safe to use with RV waste systems as it does not require a separate dump station in order for it to be properly disposed of.

• These water tanks provide the ultimate convenience when it comes to camping.


We recommend that you sanitize your RV water tank with a biocide. A quality product will kill the bacteria and break down any waste in the holding tanks, which can lead to some unpleasant smells. You should also run your wastewater hose through a filter before dumping it into an outdoor drain or septic system. This will remove anything harmful from entering natural waterways, like leaves or debris clogging up the pipes. Keep these steps in mind as you prepare for travel season!
