Sanitizing Your Fresh, Grey and Black Water Tanks

For RV owners, it might seem natural that you need to sanitize your black water tank frequently. The same might hold true for the grey water tank, but owners often don't realize that it's just as important to sanitize the fresh water tank as well, for health's sake if nothing else.

To clarify, the fresh water tank is used for faucets, toilets and showers. The grey water tank is where the water goes after being used in the sinks or showers. The black water tank is where waste goes from the toilet.

Let's start with the fresh water tank. This is perhaps not as big a bad smell threat as the black water tank or perhaps the grey water tank, but it is the source of water that touches the humans using the recreational vehicle, so there's good reason to sanitize it frequently.

The way to sanitize the fresh water tank is by adding a cup of bleach for every 15 gallons of stored water. When you add it, you need to make sure that all faucets and valves are turned off. Once it's in there, fill the tank with water and then flush it a bit before leaving the bleach in there for a few hours. Eventually, you'll need to flush through the system thoroughly to get the bleach out, but this process will definitely sanitize the tank.

When it comes to the grey tank, bleach again is the key. First scrub the shower and sink drains thoroughly, and then dump the grey tank at an appropriate facility. Then pour one cup of bleach for every 15 gallons of waste water into the grey tank. This time, however, take the RV for a 15-minute drive and return to the dumping station to drain the solution. As a final step to prevent odors, add a half-cup of bleach for every three gallons of water in the tank, and you're good to go.

The black water tank is more challenging, and here you'll need to employ water softener, laundry detergent and bleach. Basically, after dumping the black water tank, you should add one cup of liquid water softener and a cup of laundry detergent to two gallons of hot water and pour the solution down the tank drain. Then use the RV as normal and dump the black water tank when needed. The slushing of the solution during travel will help sanitize the tank and its holdings. When needed, pour bleach into the black water tank to neutralize odors.

Some RV owners don't understand the necessity of cleansing and sanitizing all three tanks, and instead just dump and/or fill them when necessary. However, for the health and comfort of all travelers, to say nothing of mechanical issues, frequent sanitizations are necessary.
