Waterway Power Defender 270 Variable Speed Pump - 230v

I gave this 4 stars because the pump operates as expected, high output, quiet when you want it to be, setup is easy. The 1 less star is because there is only 1 programming mode, which I knew ahead of time. What I did not know is that if you turn off the pump and on again to mess with the flow valves (think filter backwash), it takes a full 2 min to come back up to full speed to do a good backwash of the filter. i.e. Not very effective. There is no documentation on how to do a backwash. SO....What I have come to do is the backwash procedure while on LOW RPM. With that I can move the flow valve effectively. Start on Filter, then move valve to backwash, then force override pump to HIGH to continue the backwash cycle, then turn off override, to set the flow valve to rinse, override back to high for a few seconds, then set override off, valve to Backwash, and repeat. It works OK but kind of a pain. All in all, I am happy with the pump. Rebate from Waterway. rebate from my power company for E-Star rating. Saved a bunch of money that way.
