Abstract:

The invention is an improved sprinkler system for homes and other small requirement applications. The special apparatus and special connection arrangement is packaged into a self-contained unit for combining with a dead water tank. The system provides for a water supply to sprinkler heads from a domestic type service as a by-pass, but with an automatic full-flow supply, upon increased demand, from a dead water tank. The dead water tank has a resupply system built into it. A special test system is provided to check the system operation without opening a sprinkler head. The system is adaptable by a simple change to a dry-pipe system where freezing must be prevented.
