Hi all, I have just bought a condo with a plunge pool on the balcony (in Mexico). My pool heats up fine, but the pump or circulator or whatever that thing is when I turn the switch is so noisy with this whirring like noise. I am having a pool company come over on Monday and I am sure they are going to say I need something new. The pool is 10'6"L x 5'6" wide x 4 feet deep. I know it has a sand pump or circulator in there now because the guy taking care of the pool told me he changed the sand. I seriously (as you can tell) know nothing about pools and all I want is to be able to sit on my balcony and not hear that whirring noise when the pump goes on. What should I be looking for? The pool is super clean and the water is clear, so those things are not the issue, it is the noise. Do I need to replace the pump, the circulator, everything? It sits down in a little well-house under the stairs (3) to get up to the pool.
