π₯π§ HEATING SYSTEM LEAK DETECTION β NOT ALWAYS A LEAK IN THE PIPEWORK! π§π₯
We recently attended a property where the customerβs heating system was losing pressure daily, leading to concerns that there could be a hidden leak somewhere within the heating pipework.
Following our investigations, we established that the pressure loss was actually being caused by an issue with the heat exchanger within the boiler β rather than a leak beneath the floors or within the concealed heating pipes. π
This is an important reminder for anyone experiencing regular pressure loss on their heating system.
β οΈ Before booking specialist leak detection, we strongly recommend having a suitably qualified heating/plumbing engineer carry out the appropriate checks on the boiler and associated components first.
Issues with the boiler, expansion vessel, pressure relief valve, heat exchanger or other accessible components can sometimes cause symptoms similar to a hidden heating leak.
Having these checks completed beforehand can:
β
Rule out accessible faults first
β
Avoid unnecessary leak detection investigations
β
Potentially save the customer significant time and cost
β
Allow our engineers to concentrate on concealed pipework when leak detection is genuinely required
If the boiler and accessible components have been checked and your heating system is still losing pressure, thatβs where specialist leak detection can help locate those difficult-to-find concealed leaks. π―
