Apparently, since 85% of technicians use the SB systems, the logic must be that the other 15% just haven't "seen the light." But that's the problem. I've seen the light! It's red, and it starts flashing about a week or two after installation. That sort of thing generates a call-back, an unhappy customer, and lost revenue. I'm going to contact Dampp Chaser to ask them to reconsider making this an option and not forcing us to pay for something we will never use. If you are in the minority like myself, I hope you will also give them your feedback on this issue. Now if you disagree strongly with me, as 85% of you are likely to do, please read the rest of this email before responding. Before I started installing Dampp Chasers, I was told by a number of technicians in Arizona not to use the systems with pads lights. I had no reason to doubt them, so I never bothered with the SB systems. But last year I got curious and installed two Smart Brackets as a test, one on my own Dampp Chaser, and one with a client that I knew would not mind the experiment. Both started flashing a few days later with new pads. Both were using purified, but not distilled, water. I love Dampp-Chaser systems, and I have no doubt the Smart Brackets work great for 85% of technicians. If I had to guess, I'd guess that it has something to do with the fact 85% of users probably use tap water to fill their tanks. Tap water is full of impurities that cause the sensors to function more reliably. But in Arizona, the calcium content in tap water is ridiculous, so we urge the clients to use purified water (or distilled, as long as some treatment fluid is mixed in to make the distilled water less inert so the level sensor works properly). I've had clients who ignored my recommendation, but when they see the mess created by the bricks of calcium that build up with just 6 months of Arizona tap water, they immediately stop using tap water from that point forward. My theory is that purified water, like that which comes from my reverse osmosis system, is just too "clean" to give the SB sensor a proper signal. It works fine with the level sensor that is immersed in the water, but the contacts of the SB sensor are not immersed - they are only touching the damp pads. Mark, I'm with you on this one. I will not hook up those "idiot bar sensors"! (Period) According to Schaff the system will work with/without that stupid thingee. So,, I choose not to use it. My big beef, is, I still have to pay for the damned thing. I don't feel good about passing that cost onto my clients, if it is of no benefit to them and is omitted! It shouldn't be any big deal to offer the system w/o that. Don't understand, unless someone needs to pay off a Yacht!<G Just my take on that, Joe Joe Garrett, R.P.T.
