A friend's pool pump is needing replacement and I would like to offer some help. He has an in-ground, gunite, painted plastered pool. It is 16,000 gals with a DE filter. He also has a spa, not to mention a waterfall. He also uses a Polaris 280 with a dedicated booster pump. His current pump is by Jacuzzi...it hasn't been great since I have known him & he believes it is 2.5 hp. For a good mixture of efficiency & cost to use...can anyone suggest what pump I should recommend? I will probably be doing his install...so ease of install is important as well.
Thanks guys and ladies.
