Diagnostics
Not every plumbing problem has an obvious cause. Our camera inspections and pressure testing find the real source of recurring leaks, low pressure or mystery noises so you fix the actual problem, not just the symptom.

Common Issues
When Diagnostics Help Most
Recurring Clogs
A clog that keeps coming back usually has a cause further down the line that a camera can find.
Unexplained Low Water Pressure
Pressure testing can reveal a hidden leak or a failing pressure regulator.
Mystery Noises in the Walls
Banging or rattling pipes often points to loose piping or a water hammer issue we can pinpoint.
Buying an Older Home
A camera inspection of the sewer line before closing can catch expensive problems early.
Unpleasant Odors
Persistent odors can point to a dry trap, a venting issue or a hidden leak.
Higher Than Normal Water Bills
Pressure testing can confirm whether a hidden leak is behind a rising bill.

Noting when and where a problem happens helps us diagnose it faster.
Schedule Before Renovating
A diagnostic check before a remodel avoids surprises once walls are open.

Do Not Ignore Recurring Issues
A problem that keeps returning is worth diagnosing properly instead of repeatedly patching.
