Pipe connection between the suction and discharge side of a booster set in order to bypass water when the pumps are not in operation.
A bypass connection is a pipe diversion consisting of a manifold, two isolating valves and a non-return valve. The diversion is placed between the suction and discharge manifold of a booster set.
The bypass connection allows water to bypass the pumps from the suction to the discharge manifold.
The bypass connection is mostly used in applications where the inlet pressure is positive, so that it is possible to supply water from the water supply piping if the booster set is out of operation.
