All pipe fittings in this area MUST be Copper,
brass, bronze or Steel and must extend a
minimum of 12" above the "T" before
connecting to CPVC or PEX
All copper piping must be the same size as the fittings on the Hydro-Temp
system. Under sizing this piping will reduce the gpm flow and can damage
the unit and void the warranty. If 1" copper is used it must be reduced to 3/4"
as close to the tank as possible.
Note: on long piping runs the copper piping may need to be "upsized" to
lower the pressure drop of the circuit.
