We completed a comprehensive repair on a Master Spas unit in San Diego, addressing both mechanical failures and electrical issues. Our team accessed the internal cabinet to remove worn components and damaged insulation to make way for a complete system overhaul. We focused on restoring the unit to peak performance by replacing the primary circulation pump and the main electronic control hub. During the process, we installed a new LX spa pump and a Balboa VS Series control box, along with updated PVC plumbing unions to ensure a watertight seal. We also replaced the filtration cartridges and conducted a thorough system test to verify that the hydrotherapy jets and heating functions were operating correctly. This restoration restored full functionality to the spa, providing a reliable and efficient setup for the homeowner.
