Plumbing here, in three lines

  • Basements: heavy rain and flat ground make sump pumps and floor-drain backups common.
  • Winter: January lows average in the teens, so exposed pipes freeze.
  • Old lines: many older homes have clay sewers and galvanized or lead water service lines.

This is Decatur, Illinois

There is more than one Decatur in the country. This site covers Decatur, Illinois, the Macon County seat on the Sangamon River, founded in 1829 and home to 70,522 people in the 2020 census (Wikipedia: Decatur, Illinois). It is the city where Abraham Lincoln's family first settled in Illinois in 1830, home to Millikin University and Richland Community College, and a long-time center of corn and soybean processing.

Much of Decatur's housing went up between the late 1800s and the 1960s. Homes from those decades often have full basements, clay or cast-iron sewer lines, and galvanized supply pipe. Newer subdivisions in Forsyth and Mount Zion bring slab and basement homes with plastic pipe and sump pits.

Flat ground, heavy rain and basements

Macon County sits on flat glacial plain, part of what is sometimes called the Heart of Illinois (Wikipedia: Macon County, Illinois). Flat ground drains slowly. In heavy spring and summer storms, water collects around foundations and sewers can surcharge. That is why sump pumps, battery backups and backwater valves come up so often here. See sump pumps and the basement guide. The Illinois State Water Survey publishes rainfall and flood research for the state (Illinois State Water Survey).

Winters that freeze pipes

Average temperatures in Decatur range from a January low of about 17°F to a July high of about 88°F, and a record low of −25°F was set in February 1905 (Wikipedia: Macon County, Illinois). Pipes in exterior walls, crawlspaces, garages and unheated porches are the ones that freeze. The National Weather Service Lincoln office issues local cold warnings (National Weather Service Lincoln, IL). See frozen pipe repair and the frozen pipe guide.

Water, lead lines and permits

Decatur's city water comes largely from Lake Decatur, a reservoir on the Sangamon River built in 1920–22 (Wikipedia: Lake Decatur). The City of Decatur publishes water, sewer and permit information (City of Decatur, Illinois (water, sewer and permits)). Illinois requires water systems to inventory and replace lead service lines under the Lead Service Line Replacement and Notification Act (Illinois EPA, lead service line information). Plumbing in Illinois is regulated by the Department of Public Health's plumbing program (Illinois Department of Public Health, Plumbing Program), and any digging for sewer or water lines starts with a JULIE locate request (JULIE, Illinois One-Call (call 811 before digging)).

Guides worth reading first

All 6 guides

Getting ready to send the form

  1. Note the town or ZIP and roughly when the house was built.
  2. Say whether the home has a basement, crawlspace or slab.
  3. Describe the symptom: which drains, which fixture, after rain or in cold weather.
  4. Check the water heater or sump pump age if either is involved.
  5. Mention anything recent: a heavy storm, a cold snap, a new water bill spike.

Those details make the call back useful. The estimate-factors page explains what each of them changes.

Asked and answered

Questions about plumbing around Decatur

  1. How do I ask for a plumbing estimate?

    Fill in the short form: which project, your name, a phone number and the town or ZIP. Send the details and expect a call back to talk the project through.

  2. Is this Decatur, Illinois?

    Yes. This site covers Decatur, Illinois and nearby Macon County communities, not the cities of the same name in other states.

  3. What plumbing work can I ask about?

    Drain cleaning, sewer and main line repair, sump pumps and basement backups, water heaters, frozen and burst pipes, leaks, water softeners and fixtures.

  4. Which communities are covered?

    Decatur, Forsyth, Mount Zion, Long Creek, Harristown, Maroa, Warrensburg, Oreana, Argenta and Niantic.

  5. Why does my basement floor drain back up in heavy rain?

    When the sewer system is overloaded, water can push back into the lowest drain. A backwater valve and a working sump pump are common defenses.

  6. How do I know if I have a lead service line?

    Your water supplier keeps a service line inventory under Illinois law. You can also look at the pipe where it enters the house.

  7. Are prices listed anywhere?

    No. Plumbing jobs vary too much for a posted number to be useful. The estimate-factors page explains what changes the scope.

  8. Is there a phone number?
