If you are not able to build your control room for your DIY hot tub below ground, then you are going to need a self priming pump. But what are the options? In this blog post, I will discuss the two main options that you have for self priming pump setups on your DIY hot tub build.
What is a self-priming pump?
A self-priming pump is a type of centrifugal pump that is capable of automatically removing air or gases from the suction line and creating a vacuum to draw in and pump liquids. Unlike standard centrifugal pumps which are found on hot tubs, which require the pump casing to be filled with liquid before operation, self-priming pumps can start pumping without the need for manual priming.
