Central Heating Pressure Drop Diagnosed using Tracer Gas Leak detection.
The home owners had just had a new combi-boiler fitted but the installers were unable to commission it as after filling the system, the pressure very quickly dropped almost to zero. Although there were no signs of escaping water anywhere, a leaking pipe was suspected and we were asked to investigate.
Our Trace and Access Expert engineers quickly ascertained that there was no leak from any of the accessible pipework and that the most likely leak location was from pipes buried in the concrete beneath the quarry tiles on the ground floor.
The system was already drained (via the leak) so it was a straightforward job to introduce tracer gas into the pipework:
Two very small excavations of the concrete were then carried out where the gas had been detected and the leaking pipe was found directly under the interior wall.
The central heating system was then refilled and this time there was no pressure drop. The home owners were extremely happy as large scale excavations and the resultant mess, disruption and dust had been avoided and they could enjoy their new boiler.
