Pool specifics listed in my signature. What brand pump and horsepower do you recommend for our pool size? Our original pump is probably nearing the end of its life and would rather start the season with a new one.
Your pool does not need a 2 hp pump. Now if you get a Variable speed pump, you get the best of all worlds as you can dial in the rate needed to operate the heater, etc. But VS pumps are more expensive.
Stand alone pumps (not ties to an automation system) can be from any manufacturer. You have the big companies, Pentair, Hayward, etc, that must be installed by a dealer/professional to get the full warranty. You have InyoPools, Circupool, etc that have quality pumps and provide more generous DIY warranties. Your current pump is a Waterway pump. InyoPools markets those and I believe have replacement motors, even two speeds, that will mate up with your current wet end. Call them.
