Watershape University

If the heart of a pool is the pump and filter, then the veins and arteries are the pipes which transport the fluids or gasses critical to proper operation of the watershape. Just like in our bodies, if the circulation system is not optimized, then the whole body will not function as desired. This course not only teaches the basics for how to evaluate the plumbing system required for specific system being installed, but it also dives deeper into the specific means and methods necessary to install these elements in order to ensure the long term success of the project.
