Drain Tubes
Model: 100DT - A60 - 12
Size: 3⁄4" (20mm)
Series 100DT Drain Tubes are used to easily provide a safe
discharge line from residential water heater temperature and
pressure relief valves. No special tools, fittings or sealants are
required to install these drain tubes, they are simply handtightened to the T&P valve discharge.
Series 100DT Drain Tubes can be used on gas, electric or oil
fired water heaters to safely drain water discharged from the
heater’s temperature & pressure relief valve.
