Hot tub pumps are critical to any spa. These pumps are the mainstay for filling your hot tub with clean, fresh, sparkling water. So it is mandatory for your enjoyment that you get a good quality pump. To understand what would be the best pump for your requirements, you may want to know how the pump works.
A hot tub pump is made up of two sections. One is the wet section. This has a booster. The impeller is responsible for moving the water. The other part is the dry section. This has the electrical wires and the motor that drives the impeller. The dry and wet sections work together to remove water.
Clearly, to get a good pump, you’ll want to maximize the efficiency of both parts. There may not be much you can do with the wet part. However, you can control the power you apply to suck up the water by purchasing a more powerful pump. A pump with a higher power will cost you more, so make sure you understand how much force you need to apply to suck up the water. This will depend on two factors: the general water pressure in your area and the size of the hot tub you want to fill. Choose a more powerful spa pump if you have a larger hot tub or if the water pressure in your area is relatively lower. 3 HP and 4.5 HP pumps are available for 115V and 230V power lines.
Now that you understand how a hot water pump works and what the factors are that differentiate it, you are better positioned to select the pump that is right for you. A word of caution: no whirlpool pump is permanent. So when you get your first pump or replace your old pump, choose the best brand for hassle-free ownership.
