Northern Colorado / Larimer County
Plumber in Fort Collins, CO
Drain, sewer, leak and water heater service for Fort Collins homes, rentals and businesses, from Old Town and Campus West to Rigden Farm and Southridge.
Plumber Denver is a plumber in Fort Collins, CO for drain cleaning, sewer line inspection and repair, leak repair, water heater work and fixture installation. We handle owner-occupied homes, rental properties and commercial buildings, and you can request service online.
Fort Collins is the north end of our Front Range service area, with Loveland to the south and Windsor to the southeast. The city's water and its housing both differ from much of the Denver metro, and that changes the advice.
Soft water changes the questions
Fort Collins Utilities says its source water is naturally soft because it comes from snowmelt and rain, and that soft water can be corrosive without treatment, so the utility adds corrosion control to protect mains, service lines and home plumbing. For homeowners that has two practical effects.
First, scale is less of the story than in hard-water towns. Water heaters still collect sediment and benefit from flushing, but crusted aerators and scaled-up heating elements are less common. Second, a softener sales pitch deserves skepticism; read the utility's report before buying anything.
Not every Fort Collins address is on Fort Collins Utilities. Fort Collins-Loveland, East Larimer County and West Fort Collins water districts serve other parts of the city, with different treatment and reports. If you have pinhole leaks in copper, our pipe repair page covers the options.
Old Town, Midtown and the southeast
| Area | Housing | What to watch |
|---|---|---|
| Old Town and the blocks around City Park | Some of the city's oldest houses, many remodeled more than once | Galvanized supply runs, cast iron stacks, clay sewer laterals and roots from mature trees |
| Midtown and Campus West | Established neighborhoods; Campus West, next to the university, has many rentals | Original shutoffs and fixtures, heavy drain use, aging water heaters |
| Rigden Farm, Westchase and the Harmony corridor | Newer subdivisions | PEX fittings, first water heater replacements, irrigation backflow freeze damage |
Most trouble in the first row starts underground. Root intrusion in an older lateral starts with drain cleaning. A camera then shows whether the pipe is offset or broken, which is when sewer line repair makes more sense than cleaning on a schedule.
Rental houses near Colorado State University
A lot of houses around campus are rentals, and rental plumbing fails in predictable ways: drains used hard by several people, water heaters sized for a smaller household, and problems nobody reports until they're expensive. Between tenants, it's worth checking:
- That the main shutoff turns and every tenant knows where it is.
- The age and condition of the water heater, and whether the relief valve line runs to a safe spot.
- Kitchen and bathroom drains for slow flow before it becomes a backup.
- Toilets for silent running, which shows up on the water bill.
- Hose bibs and any exposed pipe in crawlspaces before winter vacancies.
A seasonal plumbing maintenance visit fits that turnover window well, before a new lease starts.
City permit or county permit?
Either way, the Colorado State Plumbing Board requires a permit and inspection for water heater installations and replacements, done by a licensed plumber employed by a registered plumbing contractor. Inspectors focus on gas venting, the relief valve and connections; the inspection is short, but it is the only independent check on the vent. An unpermitted water heater can also surface during a home sale inspection, when it is harder to sort out. See water heater repair and installation for repair-versus-replace guidance.
FAQ
Plumbing questions from Fort Collins
Is Fort Collins water hard or soft?
Fort Collins Utilities describes its source water as naturally soft and low in minerals, because it comes from snowmelt and rain in the Poudre River and Horsetooth Reservoir supplies. The utility adds corrosion control at treatment. If your address is served by a water district instead, check that district's own report, since treatment differs.
Which water utility serves my Fort Collins address?
Fort Collins Utilities covers the central part of the city, but its service area does not match city limits. Fort Collins-Loveland Water District, East Larimer County Water District and other districts serve outer areas, including parts of south and east Fort Collins. Your water bill names your provider.
Who issues a plumbing permit if I live outside Fort Collins city limits?
If your home is in unincorporated Larimer County, permits come from the Larimer County building department rather than the city, even with a Fort Collins mailing address. The county lists new and replacement water heaters as permitted work. Your property tax record or the county assessor's site shows whether an address is inside city limits.
