Slant Load 25 Water Caddy allows you to take 25 Gallons of fresh water with you on your next road trip and fits conveniently in the corner of your walk in tack room utilizing the "dead space" in the corner. We manufacture it with FDA approved Polyethylene so the water is safe for you and your animals to drink. Translucent poly allows you to easily check water levels in the tank. Fill cap is located on the very top middle of the water tank. Molded in aluminum 3/4" drain insert ensures the drain attachment spot will never break, sun rot or fail. One 3/4" shut off valve included. Purchase the SL-STD to get the drain valve on this caddy high enough to fill a bucket with out hooking up a hose. The strap kit provided makes installation quick and easy.
