My in laws need help and I am out of my comfort zone. Ask me anything you want about massive saltwater systems, filters, plumbing, and circulation systems, but unfortunately those skills have not transfer to small sized backyard pools
My mother-in-law has a 13,700 gallon pool with a spa of 350 gallons. It has been run by a Northstar 2hp pump (sp4015x20ns) for the past 4 years. This is the pump the company that installed the pool put on the system , it seems a bit large for the system (the company even throttled it back about 30% on the intake ball valve) but like I said I am far outside my area of expertise. The problem is that it has apparently been dry started numerous times and this pump is not a self priming pump. It was never quiet before, but now it is completely ruined and will no longer function at all. They need to replace this pump and I need your advice. I can do any type of re-plumbing and electrical work needed, but I do not know what kind of pump to replace it with.
Like I said their total water volume is right around 14,000 US gallons and I think it would be a good idea to have a self priming pump in this case. I do not really think it makes a difference, but the pump discharges through a very large micron filtration unit (capable of handling a pool of 48,000), then through a heater, and then back into the pool. It is a "saltwater" pool and for their sake I want to stay with one single speed pump. I would like it to be quieter, energy efficient, and durable than their previous pump was for them. They are on a fixed income, so price is somewhat important also. Is there any other information you need to help make a recommendation?
I have been looking at Pentair, Polaris, Sta-Rite, and Waterway. Which flow
rate would be best? Are these better than the Haywards? How would you rank them? Is there a good place to see comparisons on these pumps? They do not need top of the line just because it is the best, they need the best value for their system. If it were your pool, what brand and model would you go with?
Thanks in advanced for the help and if you ever need any help with closed aquatic marine ecosystems of any size, let me know!
