I live in Duluth,GA a suburb north of Atlanta. My brick ranch home was built in 1960, and I believe the 18x36 rectangular pool was put in not long after. My family has owned this home since 2000, and I moved in 4 years ago. When I moved in we replaced the vinyl liner and added a salt chlorination to the pool. The pump and filter have been the same since we acquired the property. There is one intake, and two outlets and a Haywood S200 sand filter with a 3/4 hp pump. They have managed to keep the pool clean for quite a long time.
