Thx all! I used the teflon lube stuff. I had some laying around for use on the pool equipment.
When I took em apart,I noticed a little wear on the inner plastic parts,almost as if they were scratched from dirt/sand etc. They still function perfectly,so not too concerned at this point. Possibly in the future,can see needing new valves. Wondering,would I need to use a new "plastic sleeve" where the plastic globe part of the valve makes contact?
In the worse case,I'll engineer my own,possibly outta stainless steel. I'll check with Chas,and or a Caldera dealer,and see what parts are out there.
Thx again all,Rich
