Drain cleaning in Thornton: what's different
Drain cleaning in Thornton depends on the age of the home. Original Thornton's 1950s laterals collect roots and debris at cracked joints, while north Thornton's newer PVC drains clog mostly from grease, wipes and hair.
A plumber clears the line with the right size cable and recommends a camera inspection if the problem is likely to come back. The lateral to the main is the owner's responsibility.

Other Thornton conditions that affect plumbing
- Aging sewer laterals in Original Thornton: Seventy-year-old sewer laterals often have cracked or offset joints. A camera inspection before a home sale or after repeated clogs is common here.
- Open plains wind: Thornton sits on open plains with little to break the wind during cold fronts. Garages, crawl spaces and exterior walls lose heat quickly.
- Newer-home water heater turnover: Many homes built in the 2000s are now on their first water heater replacement, which is a good time to add an expansion tank if one wasn't installed.

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.
