Leak Detection Services

1st Call Plumbing & Heating has recently launched Leak Locator, a new leak detection service. We have been using thermal imaging and acoustic listening technology for a number of years within the utility sector in Northern Ireland but due to an increase in demand for these services, we have now created Leak Locator.

Leak Locator uses acoustic sounding equipment and thermal images and can advise on a range of areas, including:

  • Trace and access policy for leak detection

  • Leak detection on underground pipework (domestic water supply or water heating)

  • Bathroom leak detection – concealed pipework in walls

  • New water mains to property, via moling

  • Internal metering or pulse meters

  • Zonal detection (for larger systems)

  • Pipe soundness testing (water, oil, gas)

  • Permanent fill systems to avoid low pressure

  • Pipe avoidance when drilling excavating

  • Pressure testing

  • Legionella surveys

1st Call Plumbing Testimonials

Elizabeth Deighan

Can't thank Liam and his co worker enough for a great job from start to finish. Liam quickly identified the problems with our plumbing. He kept us informed and updated on the work and always arrived on site as he promised. Really hard working and professional and left no mess anywhere in our home. Before leaving, Liam ensured we were happy with everything. We can't speak highly enough of him!
