I had a pool company winterize my saltwater pool at a summer vacation home. When I went down to check what they did, I found that the Jandy valve handle was gone from the 3 way valve between the skimmer, main drain and pump. I called to ask what happened and they told me they always remove it for the winter. I dont trust them as they closed my pool last year and didnt take it away . Is removing it SOP or did they possibly break it?
