Old Town grew up as a coal mining town, and the streets around Public Road still carry small early houses beside remodels. Most of the rest of the city is subdivision housing built from the 1970s on. Those two groups fail in different ways.
Match the repair to the age of the house
Treat this as a starting point; remodels change the picture quickly.
| Era | Where | What we check first |
|---|---|---|
| Early 1900s to 1940s | Old Town near Public Road | Corroded galvanized supply pipe, cast iron drains, clay tile sewer laterals |
| 1970s to early 1990s | Subdivisions spreading out from Old Town | Original shutoff valves, pinhole leaks in copper, gray polybutylene supply line |
| Late 1990s and newer | Newer subdivisions and infill | PEX fittings, pressure regulators, water heaters never flushed |
Not sure what your supply pipe is? Look where the main line enters through the foundation wall. Gray threaded pipe is usually galvanized steel, copper is orange-brown, and PEX is flexible plastic. Galvanized or polybutylene is a reason to read about pipe repair and repiping.
Roots, clay tile and slow basement drains
Older laterals here were often laid in short clay tile sections, and roots get in at the joints. Mature trees in the older blocks make this more likely. The first sign is usually at the lowest drain in the house. Signs the problem is the main line rather than one fixture:
- Several drains are slow at once.
- A floor drain or tub fills when the washer empties.
- The sewer cleanout shows standing water.
- The backup returns months after a cable cleaning.
Cabling the roots out restores flow, so drain cleaning comes first. A camera inspection then shows whether the pipe is offset, cracked or sagging. If it is, repeat cleanings only buy time, and the next step is sewer line repair of the damaged section.
Water heater swaps are permitted work
The inspection earns its keep on gas units, where a poorly drafting flue can spill exhaust into the house. The relief valve, its discharge pipe and the connections get checked too. Repairs are a different call: a failed thermocouple, igniter, element or thermostat can be replaced, but a tank leaking from the body cannot. Our water heater repair and installation page explains how we decide.
Freeze damage that shows up in spring
Winter here swings between mild afternoons and hard overnight freezes. The classic casualty is a frost-free hose bib that split because a hose was left attached. The hose traps water in the valve body, it freezes, and the crack sits inside the wall. Nothing leaks until spring, when you open the spigot and water runs into the basement instead of the yard. Sprinkler backflow assemblies sit above ground and crack the same way.
Pull hoses before the first hard freeze, drain the interior valve on any older spigot that isn't frost-free, and get the sprinkler system blown out in fall. If a wall or ceiling stain appears after the first spring use, shut the water off and book leak repair before the drywall soaks it up.
FAQ
Plumbing questions from Lafayette
Is Lafayette, CO water hard?
The City of Lafayette publishes its hardness results in the annual water quality report, and that is the figure to trust over a softener sales page. The supply is mostly Boulder Creek basin water blended with Colorado River water, so mineral content can shift with the seasonal mix. White crust on aerators and a rumbling water heater are practical signs of scale.
Do I need a permit to replace a water heater in Lafayette?
Yes. Colorado's State Plumbing Board treats water heater replacement as permitted work inspected by the local building authority, and the installer must be a licensed plumber working for a registered plumbing contractor. That applies to straight swaps as well as new installs, and the inspection matters most for gas units.
Why does my Old Town Lafayette basement drain keep backing up?
A recurring backup in an older house usually points to the sewer lateral. Clay tile lets roots in at the joints, and cabling only clears them until they regrow. A camera inspection shows whether there is also an offset joint, crack or low spot, which decides between scheduled cleaning and a repair.
