My pump will be needing replacement soon and I have a few questions.
I see a lot of posts telling people that their 1hp or 1.5hp pumps are too much power for their pools which are often times larger than mine.
My pool is 11k gallons with an attached spa (presently not heated, just a jets) and my pump is a Jacuzzi Magnum Force 1.5hp pump which powers BOTH the pool and spa. I don't find the force of the water coming out of the returns to be too strong at all nor do I find the vacuum suction line to be too strong either. If anything, I kinda wish I had more powerfull force of water coming out of the return fittings as I feel it would help circulate the water a little better. I can point the eyeball almost straight up and the force of the return water wont even break the surface of the water.
So is it that:
a) My existing pump was an improper selection for my pool and they should have gone smaller in horsepower?
b) The 1.5hp Magnum Force Pump of 10 years ago is equivalent to a 3/4 or 1hp pump of today?
c) Since my existing 1.5hp pump is what has worked for 10 years without problem, I should probably replace it with another 1.5hp pump when the time comes.?
d) There is no correlation in horsepower between different brands. One company's 3/4hp might be equivalent to another company's 1.5hp.
ETA: And lastly, what would be a good recommendation for a pump to replace my existing pump. Please keep in mind that I would like the maximum force possible without adversely affecting my overall system's performance. And also keep in mind that I intend to add a heater at some point (possibly a heat pump). Actually, I'd like to leave enough room (power wise) in case of any other common add on (waterfall, fountain, whatever).
