Are you looking to replace an existing hot tub circulation pump or install one in a new hot tub? Hot tub circulation pumps are essential components of your spa system as they help keep your spa clean, efficient and safe. In this guide, you will learn all there is to know about hot tub circulation pumps, and everything you need to consider before purchasing one.

What is a hot tub circulation pump?

A hot tub circulation pump is a quiet and energy-efficient device that continuously circulates hot tub water, increasing heat transfer, regulating spa temperature, and preventing the growth of bacteria. It works by pushing spa water up through the hot tub filters and jets, providing the jets with the pressurized flow needed for seat and foot massages.


Hot tub circulation pumps come in two types: variable speed pumps and single speed pumps. Variable speed models have higher flow rates and are increasingly energy-efficient, saving you time and money on your utility bills. Single speed pumps produce a steady flow of water, but offer less energy efficiency than variable speed models.


When selecting a hot tub circulation pump, there are several important features to consider. Look for a pump that has minimum and maximum flow rates, allowing you to adjust the speed with the touch of a button. Additionally, make sure to select a pump that is compatible with your spa’s size and type, as well as the included filters and jets. Finally, choose a pump that offers a minimum one-year warranty.

Installation and maintenance

Installing and maintaining your hot tub circulation pump doesn’t have to be complicated. Depending on the size and model of your pump, installation may take up to an hour. To ensure your pump runs smoothly, check for any signs of corrosion and debris, and clean the filtering system every few weeks. Additionally, make sure to check the pipe alignment and wattage consumption regularly.


If your hot tub circulation pump is not working properly, there are a few simple troubleshooting steps you can take. First, verify your pump is connected to the main power switch and that the breaker has not tripped. You can also make sure the power cord is securely plugged in and the timer of the pump is set correctly. Finally, check if any of the pipe connections are loose.
