Question 3

After a wet-pipe sprinkler system is restored following a pipe repair, water is found dripping from a sprinkler head near the repair area. What does this indicate and what action is required?

Accepted Answer

A potential leak at the repair or a damaged sprinkler head, requiring the valve to be closed again and the issue repaired before the system can be declared fully restored
