If your Lyons meter keeps turning with nothing running, or a patch of floor is warm or damp, a supply line beneath the concrete may be leaking. The Town of Lyons provides water inside town limits, and the plumbing in and under your home is yours to repair. Call the number on this page to be connected with a local plumber in Lyons.
Lyons is a small foothills town in northern Boulder County where North and South St. Vrain Creeks meet, ringed by red sandstone hills and known as the Double Gateway to the Rockies on US 36 and SH 7. The Town treats North St. Vrain Creek water at its own plant and runs its own wastewater plant, serving homes inside town limits. For sewer, the Town says residents are responsible for the line extending from their property, while it maintains the mains. Service for 80540 addresses outside town limits was not verified, so check your bill. Homes range from the historic downtown to newer houses, so the line under a slab may be older copper or newer plastic.
What to do now
- Run a quiet-house test. Close every fixture and the irrigation, read the meter, wait an hour, and read again.
- Clear the usual suspects. Listen at each toilet and check hose bibs.
- Split the system. Shut the water heater's cold inlet; if the meter stops, look at hot lines.
- Search with bare feet. Warm areas on tile or a lower-level slab are a strong clue.
- Limit damage. Close the main if water surfaces and move rugs and furniture.
- Get a locate before any cutting. Pressure testing and acoustic listening come first.
Reading the symptoms
| Symptom | Likely cause |
|---|---|
| A warm path on the floor | Hot line leaking beneath it |
| Meter moving, floors cool | Cold-side leak or a leak on the yard line |
| Wet carpet in a lower level | Water coming up through the slab |
| Poor flow at one fixture | Leak on the branch serving it |
| Water heater rarely idle | Hot water leaving the system somewhere |
Cost factors
- Time to isolate and pinpoint the leak
- Spot repair through the concrete versus a reroute through walls and ceilings
- Flooring or finished lower levels that need restoring
- Drying wet drywall, trim or carpet pad
- Permits: the Town contracts with SAFEbuilt for all building department work through the Community Core system, and Boulder County has no building code jurisdiction inside town
Ask the plumber to show you the condition of the exposed pipe; it is the best guide to whether a spot repair will hold.
