Is it the same procedure with the S20B3P2PPAS000 ??, the backer diaphragm in this NonMetallic S20 is a smaller diameter than the PTFE one, and in the video of the WetEnd Kit installation you guys are explaining it without the PTFE Diaphragm

I tried this but no good. The outer steel case does not fit over the white ptfe part. I had to discard it. I would have had to force the steel cover on and damage the ptfe white part. The previous two ptfe parts were in bits when I inspected the pump. Not impressed. !!!!!!
