October 5, 2015 - New Tees and flushing valves connection. The two brass gate valves will provide a convenient access point to connect an acid wash system to remove the mineral buildup that occurs on the Cupro Nickel heat exchanger over time. You can see some indications of a black deposit on the inside of the clear braided hoses. When I removed the one section this past summer to replace with the CPVC piping I did an acid soak on the clear 1" braided hose. I first put in CLR for about an hour which seemed to remove about 80% of the black coating. I then soaked it with Muriatic acid that removed the remainder completely.
