Boiler Losing Pressure, February 2017
Leak Detection was carried out to a detached property in Belfast, served by a Gas System boiler sited in a purpose built cupboard located in the utility room on ground floor of the property.
This boiler provides heat to 12 radiators and an indirect heating coil within hot water cylinder. The cylinder is located in a purpose built cupboard on the 1st floor, this provides hot water to all outlets.
A cold water storage facility is sited in the roof space of the property and supplies water to basin, bath and WC.
Our customer had noticed that gas boiler was needing to be refilled with water on a regular basis and on more than one occasion the boiler had defaulted due to insufficient water within the system.
A call was made to service engineer and a diagnostic test had highlighted that a new pressure relief valve needed to be fitted.
On completion of this work system continued to loose water content and leak detection was advised by service engineer.
A survey was carried out, terms and conditions were agreed and return date agreed.
Pre Test Checks
No water could be held within the heating system long enough to test boiler.
The system was made safe electrically and isolated from gas supply.
All residue water content was removed from the system and safety and pressure relief valves removed from the system for duration of testing procedures.
Following testing procedure and repairs being carried out on 2 under ground fittings the system was retested.
No pressure drops were recorded at this time.
The system was purged of all testing procedures, valves reinstated where necessary and prepared for the reintroduction of water.
Following leak detection and subsequent repairs it is recommended that the pressure in the system is observed over the next week and any discrepancies reported back to Leak Locator. It is recommended that a safety check be carried out on the gas boiler and a certificate issued.
Machinery and equipment is calibrated and tested prior to each visit and accurate at time of testing.
Please note, where pipework is ducted a variance in accuracy maybe recorded. In the unlikely event that there is more than one breach of pipework, only one area of concern can be addressed during this phase of works and this could result in a repeat of the testing procedures.
