5.Dispensing Hot Water - To deliver hot water only, the system is closed, vent valve [J] is de- energized, and the hot water dispense valve [OO] is opened. Through a combination of the force of gravity and a pressure boost from the brew pump, water now flows from the lower hot water tank cover thru a silicone tube, the hot water dispense valve [OO], a silicone o-ring, seal cover, and the hot water trough. The water does not take the same path as in the coffee brewing process because the boost in pressure form the brew pump [G] is lower than the cracking pressure of the brew path check valve [M].
