The situation
Illustrative example. Not a real job or customer.
A household's water bill is noticeably higher than the same period last year with no change in habits. There are no visible drips, the toilets seem fine and the yard is dry.
- With every fixture and the irrigation off, the meter's leak indicator is turning slowly.
- Closing the main shutoff at the house stops the indicator, so the leak is inside the house.
- Dye tests in every toilet show no color in the bowls.
- The home has a PEX manifold. Closing valves one at a time while watching the meter, the indicator stops when the kitchen hot line is closed.
- There is a faint warm spot on the floor near the kitchen island.
The leak is narrowed to one hot line, possibly where it runs below the floor, and a leak detection visit is booked to pinpoint it.
How the search narrowed
- Bill
- Higher use with no explanation.
- Meter test
- Movement with everything off confirms a leak.
- Main closed
- Leak is on the house side.
- Manifold valves
- Leak isolated to the kitchen hot line.
- Warm spot
- A clue to where along that line it may be.
Repair options a plumber would discuss
Open the floor and spot repair
- Fixes the line where it failed
- Requires finding the exact location first
- Floor patching becomes part of the job
Reroute the line
- Abandons the leaking section
- Runs a new line through walls or ceilings instead
- Avoids breaking into the slab
Takeaways
- Manifold valves
- Turned a whole-house search into a one-line search.
- Meter readings
- Gave hard evidence for the plumber and the utility.
- Billing
- Questions about the bill go to the City of Fullerton water utility.
Questions for the leak detection visit
- How will you pinpoint the leak before opening anything?
- Is a spot repair or a reroute better for this line?
- Will you give me a written report for my insurer?
- Is the hot line the only one affected?
Common questions
Is this a real household?
No. It is an invented example.
Why did the hot line leak and not the cold?
In this example that is where the failure happened. Heat cycling can stress some lines more, but a plumber would determine the cause.
Could the homeowner keep using water meanwhile?
With the kitchen hot line closed at the manifold, the rest of the house would still have water.
