Alright, here's the story. I need a replacement SWG system. I don't have/don't want to spend $1000 on a SWG at this time. A stenner is right up my alley, but more than I want to spend on such a simple device. The liquidator seems cool, and I found in on sale for $120. Not bad, but if I have to compare the price of bleach vs an SWG, the equipment needs to be nearly $0 to even make sense. Based on my crude math, it would take three years of bleach to equal the price of an SWG. If I don't want to add it by hand, it doesn't need to cost much to add it before the SWG pulls way ahead $ wise. I've seen where people have used the "buttons" to limit flow of bleach to the suction side of their pump. I've also seen people use needle valves to do the same thing. Has anyone used a water pump, like the liquidator apparently uses, to inject chlorine? I'm thinking about taking water from the pressure side of the system, after the filter, running it through the jet, and back to the suction of the pump. This is the device I'm thinking about. It's polypropylene which has decent resistance to sodium hydrochloride up until 140 degrees. http://www.amazon.com/gp/aw/d/B004AH...sZL&ref=plSrch
What say ye?
