Moving water containers doesn’t have to be troublesome! The EZ Fill-n-Roll Kit includes a 4 ft hose that makes the tank EZ to fill and a tank dolly that makes it trouble-free to move. After you fill up the water tank, simply glide or roll it from a water source, such as a spigot, sink, or water drum. Sturdy wheels make setting up your portable sink even easier – they easily handle the weight of the tank and make the tank much lighter to carry. Just glide the heavy water tank to its destination!
