Re: Upgraditis: 2-group Grimac Commercial
Im not sure Im understanding all this talk of back pressure from the HX. Unless the brew solenoid has broken nothing from the HX will flow back into the system.
The brew solenoid is between the water supply/pump and the HX. The HX is open to the atmosphere via the grouphead and the 3-way pressure relief valve. As the water in the HX boils away it will simply vent out of one of these two openings, not back into the water pipe and into the pump.
Such is the case on the Cimbalis anyways. Is there something different about this machines design that would allow this to happen?
