Reading through one of the previous Q&As, you wrote that the check valve is generally installed about 1/2 - 2/3 up the vertical section of the discharge line (assuming 5'-10' vertical section). Why so high? I've seen a few installations where the check valve is right near the base of the line. Don't know which way is better.

What are the dimensions of this check valve, both with and without the rubber connection parts installed? The current specifications read only "L x 1-1/2"W x H"

My Zoller pump has a threaded female connector on the body. What am I expected to put between the pump body and the bottom clamp of this check valve?

How important is having a check valve and how often should they be replaced? We bought a house in 04 and we have had the same check valve since we moved in. Don't know how old it is.
