Im looking to replace my pool pump with a new one. The pool does have an elevated spa and 3 little water falls on the side as pictured. All the pool equipment(pumps/heaters) are about 6-8 feet away from the pool. Now i have to replace the main pump since the bearings are going out, but it seems like the pump i currently have is overpowered. I have a 2hp pump and the pool is about 4.5-5ft deep throughout the pool, i'm positive its a less than 10000 gallons. Is this correct? If i have to stay with a 2hp pump ill get a variable speed to reduce cost but seems like i can get a 1.5hp or 1hp and be just fine. It does have a polaris cleaner pump motor as well that I need to replace, but thats more of a direct replacement. Should i stay with 2hp or can i got to 1.5? I've attached some pictures of the pool.
