We just had an in ground pool built and love it. However our first 2 utility bills were about $100 more than usual. Based on what we were told, we expected it to be around $50 more a month. Our contractor told us to run the pump 24 hours a day all the time, which we have been doing. However, from my research, very few people do this. Most say 8-10 hours a day should work. We have a Hayward Super Pump. I am considering getting a timer. Our contractor is against timers because he says that they will destroy the pump faster. It seems a lot of people use timers though. Should I consider getting a timer and running the pump around 10 hours a day? Thanks for any suggestions.
