If you do not know the age of the fresh water tank that shipped with your recreational vehicle, it's probably time to replace the unit before it springs a leak while you’re in the middle of a camping trip. When you select the RecPro 18 Gallon RV Water Tank as an aftermarket replacement tank, you will have the peace of mind to plan a long camping trip, knowing your new fresh water tank will give you the level of performance you need. Our manufacturer, Elkhart Plastics, is well known in the industry for its outstanding build quality and cutting edge manufacturing techniques that yield tanks you can trust. This tank has been manufactured to precise measurement tolerances of 29.75" x 15" x 10", so it will fit in the same space as the original tank that shipped with the RV. It will not pop out of place if you hit some rough roads on the way to your campsite. This tank has thick walls of plastic that are BPA free and NSF certified, which will keep your water safe to drink and free from external contaminants. With its boxy shape, you can store this tank on a shelf at home, at work, or on the farm and use it as a backup water tank. Each tank has 18 gallons of capacity, giving you 288 8-ounce glasses of drinking water. RecPro has all of the aftermarket parts you need to keep your RV in top condition.
