Review on Perko 0456DP7 Marine Flush Valve by Kenny Davey

Revainrating 2 out of 5

Very useful in air check valves

Ideal for winterizing or engine flushing. Installation was easy and relatively easy. The hardest part of the installation was cutting the factory hoses (they were wrapped in metal wire). I love that the kit even included an adapter that opened the check valve on the hose nozzle so a non-pressurized hose (my antifreeze reservoir) could be connected. Plus, at only $10 more than bead suction cups, this is a great permanent alternative. My boat was difficult to operate because the air intake was very close to the trailer bed.

Pros
  • GOLS certified
Cons
  • Ratio kit
