You recommended the non electric chlorine pump to take care of my Iron, manganese, & H2S. I think I prefer it to the pellet feeder. Pellets are pretty expensive. Also the chemilizer seems to be a proportional unit so I assume I can place it after my pressure tank and outside hose take off. I would like to avoid chlorinating water going to the outside hoses. Is that correct, can I install it after the pressure tank? Is this unit very loud, it will be in the basement under my kitchen and not too far from my bedroom? Also you mentioned the WQA trade show will be in Indianapolis; do you know the date? Thanks TAM (Terry)
