We are having our pool renovated (re-marcite, plus new tile and coping). Pool builder has also recommended replacing the pump, filter and heater. The pump recommendation is based on turnover (current pump is not full rated and turnover is pretty horrible); pool builder seems to prefer the cartridge over sand (I've read the pros and cons in pool school, but am interested in hearing from others); and the current heater is lower efficiency (and seems to be leaching cooper).
Here are the recommendations:
Pump: Pentair WhisperFlo - 1.5 HP
Filter: Pentair Clean and Clear Plus 520
Heater: Pentair Master Temp 250
Cleaner: Pentair Legend Platinum
We currently do not have a cleaner, so I have no idea how to compair. Pool builder also recommends and online chlorinator -- any thoughts there?
