Guides / Sewer Lines

Why sewer lines freeze

A sewer line normally drains empty, so there's little water to freeze. Problems start when water sits in the pipe or the pipe sits close to the cold.

Signs your line is frozen

Drains slow or stop during a cold snap, toilets won't flush, and there's no history of clogs. You may see ice in the exterior cleanout. If water is backing up, stop using fixtures and call — warm water from inside can't melt ice that's 40 feet away, and it adds to the backup.

How a frozen line gets thawed

We feed a hot-water jetter from the cleanout to the ice and melt it from the inside — no digging. Then we run a camera to see why it froze. A belly or sag means it will freeze again; that may call for a spot repair. Never use a torch or chemical thawer on plastic or old cast iron drain pipe.

Preventing it next winter

Mountain properties: homes in Woodland Park and Monument see deeper frost. Shallow, rocky lines are worth inspecting before winter.

Frequently Asked Questions

Can a sewer line really freeze?

Yes, though less often than water lines. Shallow sections, lines with a belly that holds standing water, and pipes exposed in crawlspaces or garages are the usual spots during Front Range cold snaps.

How do I know my sewer line is frozen and not clogged?

Timing is the clue. If drains stop during a hard freeze, especially on a line that's had no problems, freezing is likely. A camera inspection confirms it.

How is a frozen sewer line thawed?

We use hot water jetting from the cleanout to melt the ice safely without digging. Open flames and chemical thawers should never be used on drain pipe.

Is it worse in mountain towns?

Generally, yes. Woodland Park, Divide, and higher elevations see deeper frost and longer cold stretches, so shallow or exposed lines are at higher risk.
