I purchased a rebuilt? proportioning valve on ebay. You don't get what you pay for sometimes on Ebay . The company that sold it told me that the rebuilder in San Jose had told him it was resleeved. I took it apart to discover it is pitted. It looks perfect on the outside, no pits. Has anyone resleeved one of these in the past year. If so who is the best rebuilder? I've heard of Mark Frappier. Does he do the best rebuild.
Thanks in advance,
Scott
