What is the difference between 1 HP and 1.5 HP pool pump?
What is the difference between 1 HP and 1.5 HP pool pump? So, on low speed the 1 HP moves 43 GPM and the 1.5 HP moves 45.5 GPM. To save money you want to hopefully run it on low speed (much less electrical current is used on low speed and it’s more quiet).
