We helped this property owner to find the cause of a water leak in their property that other plumbers couldn't deliver.




Nu-Trend plumbing doing leak detection for a bathroom in a unit in Carlingford for a toilet

Not all plumbers have professional water leak detection equipment.

Nu-Trend is a local, licensed plumber that has a range of professional equipment that can identify & solve problems for units in building blocks. We are located in Hurstville but can service all suburbs of Sydney to solve anything from bathroom plumbing problems, blocked drains or even new renovation projects.



In this example the property owner had noticed pools of water appearing on the surface of the bathroom floor tiles. They endured this for about 9 months but decided to try and find out what the cause was.



So Nu-Trend helped this unit owner to do a leak detection test to identify where it was coming from which included a full pressure and leak test of every part of the bathroom water and drainage;

  • Nitrogen test
  • Leak test
  • Bubble leak test
  • Pressure test
  • Bucket test
  • Test Guage test
After 3 hours of intensive leak testing and investigation we found a tiny pin hole leak in the water proofing of the bathroom. It was creating a slow water leak that pooled up slowly under the tile screed and rises over time. This is what made it so hard to find and diagnose. 

We provided a quotation to do a complete waterproofing upgrade which would be to remove all the tiles and fixtures then completely re do the waterproofing and reinstate everything. It is the only way to completely repair this unit block bathroom water leak.
