1. An apparatus comprising:
- a water heat exchanger comprising a water heat exchanger inlet and a water heat exchanger outlet;
a feed valve coupled to a feed line and directly attached to the water heat exchanger inlet;
an exit valve coupled to an exit line and directly attached to the water heat exchanger outlet;
a bypass line coupled to the feed valve and the exit valve;
wherein the feed valve and the exit valve both comprise;
a bypass valve, configured to move between a flow-through position and a bypass position, comprising;
a housing comprising a first port, a second port, and a third port;
wherein the second port is in direct communication with the water heat exchanger;
a T-port actuating member located within the housing, wherein the T-port actuating member defines an internal passageway with three openings that selectively align or not align with the first port, the second port, and the third port; and
an actuator coupled to the T-port actuating member;
in the flow-through position, the bypass valve is configured to allow for fluid communication between the first port and the second port;
in the bypass position, the bypass valve is configured to allow for fluid communication between the first port and the third port and through the bypass line.

Abstract
A bypass system for a water heat exchanger is disclosed. The water heat exchanger has a water heat exchanger inlet attached to a feed valve and a water heat exchanger outlet attached to an exit valve. The feed valve and the exit valve are three-way bypass valves attached to a bypass line. When the feed valve and the exit valve are in the flow through position, fluid will flow into and out of the water heat exchanger. When the feed valve and the exit valve are in the bypass position, fluid will not enter nor exit the water heat exchanger, but fluid will flow through the bypass line.
