Review on Reliable Lead Check Valve: Aqua 20818 – Ensuring Water Safety! by Walter Day

Revainrating 5 out of 5

Check valve: easy installation and great performance!

I needed to replace my RV water heater and the block check valve was too bad to use with the new heater. My local RV shop didn't have a workable check valve (believe it or not). However, I placed an order and it arrived within two days. I wrapped it around the threads with lots of teflon tape (pipe lube would work too) and it works great! It was a very easy install and I am very happy with how it works.

Pros
  • IAPMO and NSF certified
Cons
  • Very expensive
