Here is a photo of an AMTROL WX-202 water tank and connected 1/3 HP Tait pump (has a Dayton Ohio tag) in my home. It has sat there for over 20 years connected to a big underground double-cistern that we have never used because the water company connected this area to the city water system before we bought the house. I remember back then we turned it on and it worked then. I want to eliminate this because I have no intention of ever using the cistern. Rather than trash them, are they worth anything? And who would you recommend I get to disconnect...a plumber? Thanks, John.
