Half Moon Hayrack Water Caddy allows you to take 48 Gallons of fresh water with you on your next road trip and fits most standard Hayracks. We manufacture it with FDA approved Polyethelene so the water is safe for you and your animals to drink. Transulcent poly allows you to see easily check water levels in the tank. The aluminum 3/4" drain insert ensures the drain attachment spot will never break, sunrot or fail. Each tank comes with an 8' hose kit and 3/4" shut off valve for easy ground level draining and refilling. It can also be filled using the fill cap located on top of the tank as well as a vent cap for increased draining or filling speed. Two straps are provided but it HIGHLY RECOMMENDED that you secure water caddies with tie-down ratchets to prevent movement from side to side while traveling.
