I have approximately 30,000 gallon in ground pool. I need to replace my pump and would like some recommendations. The pump has to pull the water from 1.5" pipe approximately 75' up a slight incline. I currently have a 1.5 hp pump. Do I need a larger pump? Do I need a special pump that will last with a salt water system? The reason I ask is that my pool is almost 2 years old and the pool guy said that's typical for salt water pumps. Please help!
