Your sewer line, sometimes called the lateral, carries everything from the house to the public sewer. In Pueblo, where 43.8% of homes were built before 1960 and 21.2% in 1939 or earlier, that pipe is often original to the house. Old laterals are one of the most common reasons for backups that return no matter how many times the drain is cleared.
Why old sewer lines give out
Clay and cast iron.
Many older houses were built with clay tile or cast iron sewer pipe. Clay joints shift and let roots in; cast iron rusts and scales inside until it cracks.
Tree roots.
Roots follow moisture to small gaps at the joints, then grow inside and catch paper and waste.
Sags.
Soil settles over the decades, and a low spot holds waste until it blocks.
Freeze and thaw.
Pueblo ground freezes on its coldest nights and thaws in the sun, which works old joints loose over the years.
Patchwork.
Lines repaired by past owners often mix materials, and each joint is a weak point.
Signs of a sewer line problem
- Several drains slow down at once.
- The lowest drain in the house backs up after laundry or showers.
- Toilets bubble when other fixtures drain.
- A sewer smell indoors or in the yard.
- A wet, sunken or unusually green strip of lawn between house and street.
- The main has to be cleared again and again.
Camera inspection before digging
Before anyone digs, ask for a sewer camera inspection. A plumber feeds a small camera through a cleanout and records the inside of the line. You see the roots, cracks, sags or broken joints for yourself, and how far out they are. Ask for a copy of the recording. It makes quotes easy to compare and is worth keeping if you sell.
Repair options to ask about
Clearing and root cutting
when the pipe is sound and only blocked. Roots usually come back, so this is often a short term fix.
Spot repair
of one bad section, digging only at that point.
Replacing the line
when it is cracked or sagging in several places.
Trenchless lining
when the old pipe is a good candidate. Not every line is.
Ask the plumber why they chose one option, and what the price covers: digging, putting the yard back, and any permit.
Permits and who owns what
Pueblo Regional Building Department handles building permits; call 719-543-0002 or email permits@prbd.com. The part of the line you are responsible for, and where it meets the public sewer, can depend on your address, so ask the Regional Building Department or the plumber before a big repair.
Buying an older Pueblo house
If the house was built before 1980, which covers 71.7% of Pueblo homes, think about a sewer camera inspection before closing. A standard home inspection usually does not look inside the sewer line, and a failed line is one of the more expensive surprises an older house can hold.
Common questions
What are the signs of a failing sewer line in Pueblo?
Several slow drains at once, backups at the lowest drain, gurgling toilets and a sewer smell are the usual signs. A camera inspection is how you know for sure.
Do roots really break sewer pipes?
They usually enter through small gaps at old joints and widen them over time. In clay pipe they can crack the pipe and block the line completely.
Does a sewer repair always mean digging up the yard?
No. A camera pins down the problem. One bad spot may need only a small dig, and some lines can be lined from inside.
