Deep well pump, just read a posting on this page about Gary requesting advice on well pump pressure tank. I do have one of these systems at another location. Shut the system down yesterday for the winter month's. When put back in operation in the spring is the pressure tank supposed to be pressurized before or after the electric current has been turned on the pump. This is a deep well submersible pump and 25 gallon water tank with the bladder in tank. This was all newly installed last summer. Previous system I had installed worked great for30 or more years, although I don't really have a lot of knowledge on these pump systems. Thanks, Murray
