Upon arrival to the location, I met with Ernie who was ready for us, I went with him across the street to shut the water off at the backflow. The back flows weren’t marked so after we figured out the correct one, we drained the first riser and began making our connections. Once we had everything in place, we pressed and made sure it was secured. We repeated the same thing on the other. Furthermore, I called Ernie to go turn water back on while I was on the phone to advise what was happening. In addition, no leaks were detected on both valves once backflow was fully opened. In conclusion, I hooked up the electrical and briefly explained the functions to Ernie. He has all the booklets to further investigate. Hence, he also showed me another faucet and toilet he wants replaced, asked if I could send him an estimate for that as well. In conclusion, I collected payment and all is well at the moment. *need to return in 30 days to check system per manual* This is a complete FloLogic Syst
