Trying to understand and improve on my 46 year old inground pool and to improve the efficiency and effectiveness of the various controls. Due to multiple leaks in the pressure side return lines and at the pump, I just replaced the old single speed pentair with a new Pentair Intelliflo VSF. Now trying to figure out how to upgrade the old controls to operate the spa, install a suction side cleaner, and figure how to hook the old copper pressure cleaner up to a future solar heating system.
