Installed humidifier for customer. Ran new drain line, cut out the old. Ran new wires and cut out the old. Wired in humidifier to junction box above furnace for constant power. Tommy came and helped solder couplings to remove saddle valves and he also installed Tee for humidifier. Once installed I tested and verified customer was satisfied. Sealed up old openings with sheet metal and tape. Caulked around the edge of humidifier to minimize noise. Unit operating normal.
