Drain cleaning in Fort Collins, CO
If one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.

Local conditions
Drain cleaning in Fort Collins: what's different
Many Fort Collins homes built since the 1990s, especially in south Fort Collins around and below Harmony Road, have finished basements with a bathroom or laundry room below the sewer main. Those fixtures drain to a sewage ejector pit, so a basement that won't drain is often a stuck float, a failed pump or a clogged check valve rather than a blocked pipe, and the fix is different.
Older houses around Old Town have the opposite problem: gravity drains into an aging lateral, where roots cause repeat main-line backups. A plumber first works out which kind of system the house has, clears the line or services the ejector, and then recommends a camera inspection only when a recurring main-line clog points to a pipe defect.
Fort Collins Utilities maintains the public sewer main; the service line from the house to the main belongs to the owner. If sewage backs up into several fixtures at once, the problem is usually in that private line, and a backwater valve on the lowest drain is worth discussing once it's cleared.

Other Fort Collins conditions that affect plumbing
- Clay soil movement: Expansive soils can shift slab floors and sewer lines, causing offset joints and cracks that show up on a camera inspection.
- Rental-heavy wear near campus: Rentals near CSU see heavy use of toilets, disposals and drains, and frequent turnover means problems go unreported until they're bigger.
- Cold winters: Northern Colorado winters bring long cold spells. Pipes along exterior walls, in garages and in crawl spaces freeze when heat is turned down in vacant units.
How drain cleaning works in Fort Collins

- 2
Clear it
A hand auger, a machine cable or a hydro jetter is used, sized to the pipe.
- 3
Verify flow
Water is run through the line to confirm it drains at full speed.
- 4
Recommend next steps
If roots or a sag are suspected, a camera inspection is offered before anything is dug up.
What affects drain cleaning cost in Fort Collins

Drains & sewer
Why is my basement floor drain backing up?
When water comes up through the basement floor drain, the main sewer line is usually blocked between the house and the street. Stop using water upstairs, then call a plumber to clear the main line. If it happens more than once, a camera inspection shows the cause.

Should you get a sewer scope before buying a home?
For homes built before about 1980, or with large trees in the front yard, a sewer scope is worth it. A standard home inspection doesn't look inside the sewer line, and in most U.S. cities the buyer will own that line, often all the way to the main.
Emergencies
Sump pump not working? Causes and fixes
Check power first, then the float: if it's stuck against the pit wall the pump won't start. A pump that runs but doesn't empty the pit often has a frozen or clogged discharge line or a stuck check valve. If the pit is about to overflow, call right away.
