Check out the Staypoollizer , we have had other types and all of them have give us problems some sooner then others. The toilet float type will stick in the open position eventually , they can not take the direct wave action created in a active pool. We have had our Staypoollizer for three years now and have been able to forget about it. Take a look at the reviews on any product before you spend your money. We live here in Central Florida and fortunately was recommend the Staypoollizer by the owner of a local Pinch A Penny. He mentioned they had several types of automatic pool fillers available for sale but had to many returned because of sticking floats over filling the pools , he also mention I would do good to get 3 months out of most of them. I have seen the Staypoollizer on the internet in several locations just do a search shouldn't be hard to find.
