Response to What is this gray circular knob for? It's called a grease cap? I noticed these circular side knobs on all my old (over 20 year old) Jandy valves, but when the tech was going to replace one recently that began to leak, he brought a Jandy NeverLube that does not have the side circular knob. Should I be concerned? What is the difference and should I have the grease cap knob on all my diverter valves?
