Hi, Mike,

Mas985 has given you some great info but you seemed to shuffle it aside maybe a little too quickly. Two thoughts come to my mind....Could you get your .75 2-speed pump (for the rebate) and run it on high all the time? Seems simple enough.

When you get your new pump and filter, could you replumb your booster pump line to become a suction line...or perhaps perform both functions if you use the booster pump.

I will also promise you can push more than 44gpm thru a 1.5"pipe without harm....been there, done that.

Impossible to optimize your pool? Optomize means doing the best you can....not perfection, but the best you can do with what you've got. I think you can improve your system markedly with a little more planning.
