At WOW Leak Detection Plumbing & Heating, we specialise in leak detection & are experts across plumbing, heating & drainage. Extensive system knowledge & specialist equipment help us investigate the symptoms, locate the problem & carry out agreed repairs.
Water can travel far from its source. A damp patch, pressure drop or moving meter is a symptom, not automatically proof of where the fault is.
Our work combines extensive knowledge of plumbing, heating & drainage systems with specialist leak detection equipment. Understanding the system helps us select the right methods, interpret each reading in context & compare the evidence before reaching a conclusion.
Every investigation follows a structured process of elimination. We begin by understanding the symptoms, inspect the affected areas, separate possible sources & choose the tests that suit the system. No individual reading is treated as proof on its own; the evidence is compared before targeted access, repair or further monitoring is recommended.
Once the investigation is complete, we explain what has been found, what remains uncertain if conditions limited the testing, & the most practical next step.
