A fresh water tank for your recreational vehicle is probably not the primary thing on your mind when you're preparing for a long camping trip. But if you are not sure just how old the drinking water tank that shipped with your RV is, it may be time to replace it before it fails in the middle of a trip. The RecPro 31 Gallon RV Water Tank will deliver the level of performance you need, while also giving you a great value over time. Elkhart Plastics is the manufacturer of this tank, meaning you can count on the quality of the BPA free and NSF certified materials to keep your drinking water fresh and free from contaminants. With the thick plastic walls in our 31-gallon fresh water tank, it will keep external contaminants away from the water too, including dust from a rural road. With dimensions of 43" x 20" x 9", this tank will precisely fit in the same location as the OEM fresh water tank currently in your recreational vehicle, reducing the chances of any leaks in the system. Because of the boxy shape of the EPI 4377 tank, it works as a backup storage water tank on the farm, at home, or at work, fitting nicely on a shelf. The fresh water tank supplies your drinking water, as well as water for bathing or washing dishes, so you do not want to risk a leaky tank leaving you short on water. With 31 gallons of capacity, our fresh water tank can deliver almost 500 8-ounce glasses of drinking water. RecPro has the aftermarket parts your RV needs to keep it functioning in a life-new condition.
