I'm in the process of building a pool and need to make a choice re: the main pump. This pump will only be responsible for filtering/cycling water. This is going onto a ~27K gal salt water pool.
Here are my three choices (I'm looking at jandy to match rest of equipment):
1HP single speed. That's plenty of power and flow rate to do what needs to be done, but the pump always runs at full speed even when all I need is to run the water through swg and don't really need the skimmers engaged
1HP 2 speed, this pump will allow me to run @ full speed for cleaning/ vacuuming and half speed when I just need to produce chlorine. There are 2 concerns there: for some reason my pb does not like 2-speed pumps; I'm not sure that running @ half speed will produce enough flow to keep SWG engaged (it needs 30GPM according to peer curve it can produce that but a relatively low TDH)
Use ePump (1.5 or 2 HP) VS
I guess I could also look at 1.5HP 2-speed, but then half speed will look a lot like 1hp single speed.
