The central heating pipework was damaged by a screw, causing a water leak. The customer had already shut off the water supply, and the heating system was almost completely drained.
We cut out the damaged section of pipework and vacuumed out the remaining water. The damaged pipework and necessary connections were replaced.
The system was then refilled with water and tested thoroughly. No further leaks were found, and the customer confirmed that there was no visible leakage.
