Mounting Your QMP Air Gap Faucet
- Drill a 1.25" to 1.5" hole in your sink deck or countertop, ensuring adequate clearance below for tubing connections and the air gap chamber.
- Insert the faucet shank through the mounting hole from above, then secure from below using the included QMP522 washer set and mounting nut, tightening hand-tight plus a quarter turn with a wrench.
- Connect the filtered water supply line to the inlet port and the drain line to the air gap outlet port, following your reverse osmosis or filtration system's plumbing diagram.
- Turn on the water supply and check all connections for leaks, then operate the ceramic disc handle through several cycles to verify smooth quarter-turn operation.
System Requirements
The QMP804AG-BSS is designed for use with under-sink reverse osmosis systems and filtration units in jurisdictions where air gap protection is mandated by local plumbing codes. The air gap feature physically separates filtered water from drain water, preventing any possibility of backflow contamination. This faucet works with standard 1/4" tubing connections common to most residential RO and filtration systems. The brushed stainless steel finish coordinates with modern kitchen fixtures and resists fingerprints and water spots better than polished chrome.
