This Perko Flush Pro Valve Kit finally makes freshwater flushing of an inboard engine as simple as connecting a garden hose. No more improvised muffs or buckets required.
It’s built from polymer with a stainless steel spring. A transparent body allows visual inspection of water flow, so it’s obvious at a glance that water is actually moving through the system.
A durable check valve system activates by water pressure from a garden hose. It automatically shuts off hull intake when water pressure is present, protecting the engine from drawing in outside water during the flush. Explore more marine pipe fittings.
