I recently purchased a home that has a chlorine injection system. It was banked owned so I was given no information on how it works. I have always had city water so having a well is new to me. Does anyone know what type of chlorine is needed for this system? I found something on-line that mentioned using regulat household bleach? Is that acceptable? The system is a Uni-Dose by LMI, model U041-281. I have tried the local DIY stores, but all they seem to know about are water softeners, and I do know that's not what I need!
