Why Replace Your Sundance Spa Flow Switch?

If you’re experiencing issues with your Sundance spa, one of the components that may need to be replaced is the flow switch. The flow switch is responsible for detecting whether or not water is flowing through the system, and if it’s not functioning properly, it can cause a number of problems. Here are a few reasons why you might need to replace your Sundance spa flow switch:

Firstly, if you notice that the water in your spa isn’t heating up properly, this could be a sign that your flow switch is faulty.
