A lot of people have fixed their SQE by converting it to a regular SQ, and using a CSV and pressure switch. The CSV and pressure switch could be installed by just about anyone. And yes it will even work with the 2 gallon tank. Use one of the CSV1W or CSV1Z valves in the basement before the pressure switch and tank, as long as no water lines are tied in before that. I am sure you will be happy with the conversion but, please let us know how you like it.
