So I just bought this house and it is the first time I have ever owned the pool. Been following all the suggestions and pool water clearing up nicely and chemistry getting there. As seen below my pool has two 3/4 hp pumps. The main Heyward pump works fine but the Century booster pump is locked up and doesn't work at all. Do I need a booster pump for normal operation of this pool? Is the booster pump just for vacuuming? Thanks for helping me with these questions.
