Bought a supposedly new Jandy 2-way neverlube valve off ebay, and it came in with small amount of water inside and some crack lookalike stuff on the body. The seller was claiming those were cast marks and showed me at least three more valves with similar marks, and said the Jandy valves sometimes shipped with some water to keep the seal wet. It sounds odd for the water theory. I bought same valve from other seller without these marks and dry.
Have you ever heard of this theory at all?
