RV Water Tank Storage


Draining, Flushing and Cleaning RV Fresh Water Tanks

People who are keen on transient RV lifestyles definitely need RV water tank to help make motor home comfortable.


There is nothing more distressing than waking up in the middle of the night in your mobile home and finding out there’s no hot water much less, “water”, in the toilet. Every happy camper or RV lifestyler could not do with an RV hot water tank.

Recreational vehicles can be used for short vacations and camping. You can also use them as your permanent home parked in trailer parks. There are different types of recreational vans. Four of the most popular types are Class A and Class C, camper van and travel trailer.

Equipment and provisions for RVs differ as they are equipped accordingly, but whatever your reason for using an RV, there is always a need for water tanks.

You need three RV water storage tanks -one for fresh water, one for gray water and another tank for black water. An RV fresh water tank is for storing sanitized fresh water for human consumption like cooking, cleaning and bathing. Gray water holding tanks are for collecting dirty water from the bathroom sink and shower and from the kitchen sink. An RV black water tank is for collecting human waste from the toilet. Both types of tanks are emptied RV dump stations.

Unfortunately most of these dumping stations are closing shop because RV-ers use harmful chemicals in the septic systems. It is therefore mandatory to use “green” chemicals for the treatment of gray and black water. Steer clear of formaldehyde for treating waste water, and don’t try to put any chemicals in RV water tanks.

Drain out the RV black water holding tank when it is at least 2/3 full. The gravity and weight of the almost full tank will push the contents of the holding tank to empty out properly into the dump stations. Never ever leave the valve of the black tank open and expect it to flush and drain on its own as it will not happen. It is best to dump the black tank first, followed by the gray tank. Flushing or cleaning these RV water storage tanks is a must for sanitary and health purposes.

RV fresh water tank comes in different shapes, brands, models and size. If you use a traditional water heater for your mobile home, then it is best that you get a bigger capacity water tank. Storage capacities differ. There are brands that offer models with a capacity of up to 180 gallons. RV water storage tanks that use a boiler to heat up 120 liters of water is well and good as long as you have the necessary space for a big tank, not to mention the two additional tanks (fresh and gray water)that are needed.

The 5 gallon RV water tanks and the 6 gallon water tanks sound like the perfect choice for your mobile home. Most of these RV water storage tanks are made of polyethylene material approved by the FDA. This material is safe for storing potable drinking water and is strong enough for gray and black water holding tank. Thickness of plastic walls is from ¼” to 3/8”.
