Hi, just joined today. I have no experience with pools, but am wanting to learn. I live in a condo in Mexico and as one of only a few full timers, I have been asked to help out. We currently have a pool maintenance man looking after the day to day testing, vacuuming etc. What I would like to find out with this post is, how do I determine how often our pool water should been turned over. I have checked the Hayward site and printed off the owners manual for our pump and it states 80 gpm with 2" pipe. Another source from Hayward states 80 gpm up to 159 gpm, depending on head pressure. I believe I need to clarify this gpm info before I can figure out a turn over rate. Can someone direct me to the correct location on this board for help?
