Barn Conversions and Pipe Runs Without a Map
Converted farm buildings tend to have heating and water pipes laid for one phase of the work and extended for the next. Long runs, changes of pipe size and joints buried in walls built during the conversion are all common, and when one of them leaks the water can travel a good distance along a beam or through a void before it appears.
We start with what the system can tell us, which circuit is losing water and roughly how quickly, then shut off sections to close in on it. In a building where nobody knows the route the pipes take, that saves a great deal of exploratory damage.
