I am beginning a massive remodel to my house, and for reasons of drainage and grading I am beginning with block retaining walls and the pool. I definitely want to use a SWG, but the people I talk to are attemptng to steer me away from using a salt water generator. My city (Sierra Madre, Ca.) draws it's water from wells at the base of the San Gabriel mountains, and it has a very high mineral content. I am advised that the minerals, in conjunction with the SWG add up to very short life for the pool equipment. They said to expect 2,000 hours for the generator, and for the heater to last 2 to 4 years before it has to be replaced. My main advisor has been building high end pools for 30 years, and we were roommates in the past...he's not making a buck on my project, but is letting me use his crew, and also his wholesale accounts, so I know he has my best interest at heart. He says the vendor reps that he deals with don't know why this is occuring. Does anybody else out there have similar, or opposite experience in dealing with SWG's and high mineral content water? Thanks.
