Hot water supply and return piping connects to the reheat coil via typical unions and reducers as required. The supply line includes a strainer with a valve and hose bibb connection, ball valves, a balancing valve, and a temperature control valve. A Pete's plug is installed for temperature and pressure measurement. The return line includes a half-inch air vent positioned at the high point of the piping arrangement.
