What is a hot tub circulation pump?

A hot tub circulation pump is a special type of pump that is used to circulate the water in a hot tub. A circulation pump is distinct from the main pump that runs the jets, and is instead responsible for moving water around the system continuously to provide 24/7 filtration.

Not every hot tub has a circulation pump, but the theory is that they help to keep the water clean by circulating in a quiet, energy-efficient way.

Without a circulation pump, hot tubs rely on just the standard pump to circulate the water by running the jets—both when the tub is in use, and on low speed during filtration cycles.

Most circulation pumps are designed to last for many years, but they can eventually wear out. If your circulation pump stops working, it will need to be replaced.
