How is a large leaking water supply pipe repaired?
Once the leaking water has been detected the water supply pipe is excavated and fully exposed in order to ascertain the full extent of the water leak, in this instance the water supply pipe has split all the way around.
The likely cause of this broken water pipe, which caused a catastrophic failure of the fire sprinkler system was ground movement. In this particular case the fire sprinkler system and water supply pipes were installed during Victorian times, it is quite extraordinary that the condition of the remaining water supply is in excellent condition after all this time.
The best method of repairing this type of water supply pipe fracture is a repair clamp, the water pipe is sandwiched between the clamp and the bolts are tightened firmly, the fracture is then securely sealed and the rubber gasket inside the fitting is compressed to ensure no further water leakage.
