What the method adds
An appropriate dye test can help examine certain water paths around fittings and wastes. The choice of test depends on the surfaces, access and question being investigated.
Conditions and limitations
A result needs careful interpretation. Dye testing is not suitable for every installation or leak.
Useful preparation
Describe which use triggers the symptom and any particularly sensitive finishes.
From result to repair
Equipment readings are considered with the system layout, symptoms and other findings. Where access is justified, the opening and plumbing repair are agreed as part of the instruction. Detection does not remove the need to reach a concealed pipe.
