Case type
Tankless systems
Scale, fault codes, poor performance, and systems that stop delivering reliable hot water can all point to an underlying issue.
The evidence
What we look for
- Error or fault codes on the unit
- Cold-water sandwiches or weak hot water
- Scale buildup and hard-water symptoms
- Ignition or combustion-related issues
- Skipped maintenance or filter neglect
The investigation
How we work the case
We read the system’s clues — codes, flow, temperature rise, and service history — to separate a maintenance issue from a component or installation failure.
The solution
Case closed
Service, repair, or replacement guidance is based on what the unit is telling us, not guesswork.

Other investigations
- Water heatersLeaking tanks, failing components, aging units, and heaters that no longer deliver the hot water your home needs.
- Hidden leaksWater can travel away from its source before it becomes visible. We investigate the signs and trace the leak back to where the case began.
- Water serviceThe line connecting the meter to your home can fail, leak, or restrict flow. We investigate the service line when the evidence points beyond the fixtures.
- Water pressureHigh or low water pressure is a clue, not always the cause. We trace the pressure problem back to its source.
- RepipingSometimes the problem is not one fixture or one connection. When the piping itself has become the issue, we investigate the condition of the system and determine the appropriate path forward.
- ValvesA valve that leaks, sticks, or fails to shut off can create a larger plumbing problem. We identify the failure and address the source.
- DrainsSlow drains and recurring backups leave clues. We investigate what is affecting the drainage system rather than simply treating the symptom.
- Gas pipingNew gas lines, corrections, and related plumbing work completed according to the requirements of the job.
- Code correctionsWhen existing plumbing does not meet current requirements, we identify what needs to be corrected and bring the affected work up to code.
- Unusual problemsNot every plumbing problem follows a familiar pattern. When the symptoms do not match a standard failure, we investigate the case from the evidence up.
