Long time lurker, first time poster.
I have a ~20,000 gallon in-ground pool. For years, I have been using a free-to-me 1.5HP Hayward Power Flow LX (SPX1580x15) pump and a small sand filter to circulate my water. I have decided to upgrade my filter and pump because my current set-up isn't moving enough water. The pump was previously used in a very small (maybe 10'x10'x4') pool, so it may have a smaller impeller installed. Either way, the pump is ~15 years old and I am tired of messing with it...
I was considering getting a new variable speed pump, but my electric rate for off-peak usage is only 4.7 cent per KWH. I don't think that I can justify spending the extra money since my power is dirt-cheap 20 hours out of the day.
I have already installed my new sand filter. It is a Hayward S224T.
SETUP: My floor drain goes into my strainer basket, which is a single 2" inlet to the pump (currently necked down to 1.5"). I have two 1.5" return lines to the pool. One splits to two jets and the other return is for my Polaris 360. No heaters, no SWG (at this time).
I am trying to decide between a two 1.5HP Hayward pumps, the Super Pump II and the Tri-star. I am open to buying a two-speed pump, but with my power being so cheap, I am tempted to go all Tim "the Tool Man" Taylor and throw a big-bad single speed pump that will move some serious water.
Thanks in advance,
