Rear Connection—119 gallon tanks have a 2" NPT spud for a rear water connection.
Two Protective Magnesium Anode Rods—Provide added protection against corrosion for long trouble-free service.
Steel Tank—Heavy gauge steel automatically formed, rolled, and welded. T&P Relief Valve tapping on side of tank & port for 3/4" NPT Aquastat.
