Designed to keep water level below the rim of 8" or higher sinks, preventing spill-overs, this 7" bar sink overflow pipe with rubber cap is especially helpful in busy three-compartment bar sinks to keep the rinse sink water clean without the sink overflowing. Also useful in kitchen prep sinks for thawing foods by the FDA Food Code cold water method or for washing produce, the polypropylene overflow pipe has a rubber cap on one end that provides a snug fit in sink drains to allow a sink to fill to 7" without draining. The drain overflow pipe is 7" long x 1" in diameter, and the rubber head fits any 1-1/2” IPS drain.
