I’m installing my Stenner pump this week and realized my pool builder installed the puck chlorinator to serve only when in Pool mode, not Spa mode. In other words, the chlorinator is downstream of the valve that splits return flows between the pool and the spa, on the pool side. Seems wrong to me since no disinfection is happening when people are in the spa. Am I missing something or is this wrong? I plan to tap the liquid chlorine injection point downstream of the heater and all equipment, but upstream of the splitter valve. Thoughts?
