Air-Gap Protection for Toilet Fixtures

The Kingston Brass K801 air gap installs on a toilet supply line to stop back-siphonage from drawing contaminants into the potable water system. It is intended for residential and light-commercial bathrooms where local plumbing codes require an atmospheric vacuum breaker.

Chrome Headpiece with ABS Cap

The solid brass headpiece resists corrosion while the non-metallic cap prevents galvanic interaction with dissimilar metals in the supply line. Together they maintain a consistent polished-chrome appearance that coordinates with other Kingston Brass fixtures.

Verify 5/8" × 7/8" Supply Compatibility

Confirm that the existing toilet supply connection matches the 5/8-inch by 7/8-inch sizing before ordering. Measure available clearance around the inlet to ensure the 26.5-inch overall length and 3.5-inch width will fit without interference.

Questions about this item

Will the chrome finish or the 5/8" x 7/8" air gap connections need replacement over time?

The solid brass headpiece and engineering-grade ABS construction are built for durability, while the polished chrome finish resists corrosion; the non-metallic cap may eventually require replacement if it becomes brittle.

What limits continuous operation of the K801 air gap?

The air gap relies on atmospheric pressure to prevent backflow, so its functional limit is the plumbing system's supply pressure; the 3.5-inch width and 26.5-inch length do not restrict flow under normal use.

Does the unit generate noise, heat or draw power when running all day?

The K801 is a passive plumbing device with no moving parts, motor or electrical connection, so it produces no noise, no heat and consumes zero power during continuous operation.
