Review on πŸš— Toyota Lexus 85321-28020 NEW Koauto Wiper Washer Windshield Check Valve: A Reliable Solution by Mar Pacora

Revainrating 1 out of 5

Spring too strong

OK, OK - I am NOT using this for an OEM application. I needed a one way valve for a Longbridge manual washer on a 1959 Austin Healey 100-6. But we need all the volume this valve can easily miss. I was surprised at how much unnecessary back pressure the valve has due to the overly heavy check valve spring. Okay --- if you have an electric pump, you're probably fine. But why do you have back pressure? Ok, I'll try another one. $3.98 isn't bad for R&D!

Pros
  • Comfortable to use
Cons
  • No
