New to this forum and new to the world of pool ownership. Just bought a house with a 27,000 gallon in ground vinyl lined pool. The pool has been in since 1986 and most of the equipment is between 10 and 15 years old. Last week the old Sta-Rite pump gave up the ghost. No water coming from the strainer basket and no pump pressure in the sand filter. Local equipment service center is recommending a Pentair SuperFlow 1.5 HP 230v single speed replacement pump installed for about $870. My question is could I have them install a 2 speed version of this, assuming I can figure out if the Gold Line controller can handle a 2 speed pump. I'd like to reduce the energy usage of the pump if possible.
I may be thinking about this incorrectly so I'm looking for any experience for guidance.
