Conclusion

A sump pump for a hot tub is typically used to remove water that has accumulated in the tub. This may be due to rainfall or other sources of water. The sump pump will typically have a float switch that will turn the pump on when the water level in the tub reaches a certain point.

The pump will then remove the water from the tub and discharge it into an appropriate drainage area.
