The Portable Wash-Ware Stainless Portable Sink with Electric Pump by Acorn Engineering company makes adding a new handwashing station quick and easy. This portable, freestanding sink is only intended for indoor use as the pump requires access to a GFI outlet. Heavy-duty casters and handles on either end make for smooth transport. Two of the four swivel casters come equipped with locks to keep the sink stationary. A 5-gallon tank for fresh water and a 6-gallon for waste is stored beneath the sink. Fresh water is delivered to the faucet by an on-demand electric pump. A door on the front of the sink conceals the tanks, pump and plumbing connections. Holes are provided in the back to secure the sink in place with a lock and chain. The Portable Wash-Ware Stainless Steel Sink with Electric Pump arrives pre-assembled, simply add a compatible faucet and it’s ready for use. For hands-free operation, a sensor faucet is available.
