The Mr Drain MD-10A Air Gap features the ability to share a 1-1/2" to 2" metal or PVC standpipe with a drain hose or metal drain hook. This air gap is designed to work with water softeners and some kidney dialysis units. Air gaps are critical because they allow an "air gap" between the drain hose and the drain itself to prevent back siphoning. The manufacturer recommends one MD-10A for usage between 1 to 7 GPM. Two Mr Drain air gap units can be installed back to back in a 2" standpipe if higher GPM is needed. The Mr Drain Air Gap protects against backflow and back siphonage. The MD-10A is dual listed with NSF and UPC.
