Water Inlet Components:
Brew Gauge: The brew gauge reects pressure in the brewing system. On an MVP, there is one gauge for
the enre brew system; on an MVP Hydra, each brew tank has its own brew gauge. The gauge normally
moves between 3-5 bar (line pressure) to 9 bar (brewing pressure) and up to 12 bar (expansion pressure) at
which point the expansion valve releases the excess pressure.
Brew Tank Check Valve: Check valves are one-way valves which ensure that pressurized water cannot over-
whelm the incoming water pressure and exit the machine through the inlet lines.
Brew Inlet Hose: Supplies the brew system with water from the pump. Hydra models have a pump, motor,
and hose for each group. A 3 group MVP Hydra will have 3 hoses, 2 group - 2 hoses, and 1 group - 1 hose.
Drain Box: Water ows into this box prior to going through the drain hose to the oor drain. Periodically
pour small quanes of hot water down this drain box to clear coee oil buildup.
Drain Hose: Waste water and some grounds go down this tube to the drain. Keep this free of clogs and
maintain a steep vercal path to the oor drain.
