This is my first post to this forum, which I joined to mine all the information I could from you long-time pool problem-solvers. Before I submit my problem to the experts, I must perform two additional tests ( suction-side vacuum & timed fill-the-buckets flow-rate tests). I have read the Pool-School data and Hydraulics 101 treatise and have done the bucket test to determine whether leake exist. I have also done the shaving-cream test around the rim of my pump basket & all suction-side valve stems ( no leaks). With regard to this thread, I am replying to the query about placing the equipment pad below pool surface level. My pool was built in 1954 on a 30* hillside, using an existing garage as the form for the concrete. The pool depth is 8-1/2', even with the floor of the garage. The concrete pad to the rear of the garage is 3' higher then the floor. As my signature says, the pad is 5-1/2' below pool level. While I have had my share of problems in 40-1/2 years, I cannot positively pin any of them on the placement of the pad. After I perform the next two tests I will submit my problem to the Equipment Group members for their considered opinions.
