Kit for modifying operational mode of impact sprinkler

A kit for modifying an operational mode of a step by step rotatable sprinkler head from full-circle operation in only a forward direction to part-circle operation in both the forward direction and a reverse direction, the sprinkler head being attached to a water supply riser via a fitting, the kit comprising:

• a trip assembly module configured for engagement to the sprinkler head, the trip assembly module comprising,
• a lower trip having a lever, and
• an upper trip having a receiver,
• wherein the lever is mechanically coupled to the receiver so that when the lever moves between a first position and a second position the receiver switches the operational mode of the sprinkler head between the forward direction and the reverse direction;
• and
• one or more trip stops configured to be secured relative to the fitting and intermittently contact the lever to move the lever between the first position and the second position.

A step by step rotatable sprinkler head modified from full-circle operation in only a forward direction to part-circle operation in both the forward direction and a reverse direction by attachment of a kit, the sprinkler head comprising:

• a rotatable sprinkler body adapted to be coupled to a source of water under pressure via a fitting;
• a nozzle attached to the sprinkler body for discharging a stream of water therethrough;
• an impulse arm mounted to the sprinkler body, the impulse arm having a water engaging portion for repelling the impulse arm from the stream of water upon engagement therewith;
• a spring connected to the sprinkler body for biasing the impulse arm for movement in a direction for engagement with the water stream being discharged by the nozzle;
• a trip assembly module coupled to the sprinkler head;
• an assembly module clip locked to the trip assembly module;
• a trip stop adapter configured to secure to the fitting;
• and
• one or more trip stops configured to secure to the trip stop adapter.
