Douglas County / Douglas County (unincorporated)
Plumber in Highlands Ranch, CO
Water heater, drain, leak and sewer line work for Highlands Ranch homes, from the first 1980s houses in Northridge to newer builds in BackCountry.
Plumber Denver works as a plumber in Highlands Ranch, CO for homeowners and businesses across all four ridges. We repair and replace water heaters, clear drains, fix leaks, install fixtures, repipe, and inspect and repair sewer lines.
Highlands Ranch is unincorporated Douglas County, not a city, so permits go through the county rather than a town hall. The first homes went up in 1981, which makes the oldest neighborhoods more than 40 years old. Original valves, supply lines and drain lines in those houses have had a long run.
Match the likely problem to when the house was built
Highlands Ranch filled in over four decades, so plumbing trouble tends to follow build era more than street name. Northridge holds many of the original 1980s homes; the gated BackCountry community opened in 2007. Treat this as a starting point, not a diagnosis.
| Build era | What we check first |
|---|---|
| 1980s to mid-1990s | Water heater age, stiff or seized shutoff valves, and any gray polybutylene supply pipe, which was used nationally from the late 1970s to the mid-1990s |
| Late 1990s to 2000s | Second or third water heater, worn toilet fill valves, braided supply hoses past their service life, sediment in tanks |
| 2007 and newer | PEX fittings at manifolds, sprinkler backflow devices left charged over winter, faucet and shower cartridges |
A remodel changes the picture. If a previous owner finished the basement or redid a bathroom, what matters is what is behind the wall now. We look before recommending pipe repair or a partial repipe.
Replacing a water heater under Douglas County rules
Because Highlands Ranch is unincorporated, the Douglas County Building Division is the permitting office. The county requires a mechanical or plumbing permit to install, alter, repair or replace a plumbing system, and it handles a straight water heater replacement as a basic permit with no plan review.
The Colorado State Plumbing Board takes the same position statewide: replacing a water heater is plumbing work for a licensed plumber employed by a registered contractor, and it needs a permit and an inspection.
Our water heater repair and replacement page explains how we decide between fixing a unit and replacing it.
Get the yard and basement ready before the first hard freeze
Front Range winters swing between mild afternoons and nights well below freezing. That cycle is hard on anything holding water outside the heated part of the house. A short list for Highlands Ranch properties:
- Shut off and drain the sprinkler system, including the backflow device, before the first hard freeze.
- Disconnect garden hoses so frost-free hose bibs can drain.
- Look for supply pipes on exterior basement or garage walls with no insulation.
- Find your main shutoff and confirm it turns. A valve that has not moved in 20 years often sticks.
In the older ridges, trees have had decades to grow, and roots work into sewer laterals at the joints. Slow drains in several fixtures at once point to the main line rather than a single trap, which calls for a sewer line inspection instead of another bottle of drain cleaner.
FAQ
Plumbing questions from Highlands Ranch
Do I need a permit to replace a water heater in Highlands Ranch?
Yes. Highlands Ranch is in unincorporated Douglas County, so the county Building Division issues the permit. A like-for-like replacement is handled as a basic permit without plan review. State rules also require the work to be done by a licensed plumber with a permit and inspection. If the old unit fails suddenly, the county lets the application follow within the next working business day.
Is Highlands Ranch water hard?
Highlands Ranch Water publishes an annual water quality report that includes a total hardness figure, and that report is the number to use when deciding on a softener. Most of the supply is treated South Platte River water, with Denver Basin groundwater as a backup source. Mineral scale shows up first in water heaters, faucet aerators and showerheads.
Who do I call about a water main break or low pressure on my street?
Problems with the public mains belong to Highlands Ranch Water, the district that serves Highlands Ranch and Solstice. If the trouble is inside your home, such as one fixture with low pressure, a leak under a sink or a failing water heater, that is a plumbing repair. When you cannot tell which side the problem is on, call the district first.
