Replace them last spring, the back one went bad.Replacing the pillow blocks too?
The Kleenrite tools I used for 40 years had an internal hose connection in the cuff, HydraMaster chose to go with the hide a hose style cuff. If you are working around the different side of a sofa and the hose gets hung up on anything, the plastic hose can crimp or fold over on itself.Why did it do that?
