Lyons is a small foothills town where homes inside town limits get water from the Town of Lyons, treated from North St. Vrain Creek. When older supply lines keep leaking or flow has faded, a plumber can replace them with PEX or copper. Call the number on this page to be connected with a local plumber in Lyons.

Lyons in brief
Lyons sits where North and South St. Vrain Creeks meet, ringed by red sandstone hills, and calls itself the Double Gateway to the Rockies on US 36 and State Highway 7. It incorporated in 1891 and keeps a historic downtown. The fact sheet does not include a year-built breakdown, so your own house's age is the best guide to whether original pipe is wearing out. The Town of Lyons provides water and wastewater service inside town limits, drawing from North St. Vrain Creek and treating it at a town plant. The pages reviewed for this site do not say where the town's side of the water service line ends, so ask the plumber to confirm with Town Hall before any buried line is added to the job. Service for 80540 properties outside town limits was not verified; if you are outside town, check your water bill.
What to do now
- Shut off the water at the fixture or main if a line is leaking.
- Record each leak: room, date and whether it was a fitting or the pipe.
- Look at exposed pipe at the water heater and in any crawl space.
- Check flow at the farthest fixture with another tap open.
- Wait on finish repairs to drywall until the scope is clear.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Leaks moving from room to room | Supply pipe aging throughout the house |
| Weak flow at every fixture | Galvanized steel narrowed inside |
| Brown water at the first draw | Corroding steel pipe or fittings |
| Split line after a cold night | Freeze damage in an exposed run |
| Leaks where old and new pipe meet | Weak transitions from earlier patches |
Cost factors
- Scope: one zone or the whole house
- Access under floors and through finished walls
- Older finishes in historic homes
- PEX or copper
- Patching after the new lines are in
Permits inside town limits go through the Town of Lyons Building Department, which the town contracts to SAFEbuilt; applications run through SAFEbuilt's Community Core system, and Boulder County has no building code jurisdiction inside the town. The plumber normally files the application and books the inspection.
