Can I flush the toilet during a septic backup?

No. Every flush adds water that has nowhere to go. Hold off on all water use until a septic company has found and fixed the problem.

Will pumping the tank fix a backup?

Often it gets the house draining again, but it may not fix the cause. If the drain field or a pump has failed, the tank will refill and the problem will return, so ask for a diagnosis along with the pumping.

Should I call a plumber or a septic company?

If only one fixture is slow, a plumber may clear the clog. If several drains are slow or backing up, or there is an alarm or odor near the tank, call a septic company.

Does fixing a septic emergency need a permit?

Pumping and small repairs usually do not. Larger repairs and drain field or tank replacement often do. Check with the Cook County health department, or ask the septic company to handle permits for you.

Septic Backup or Alarm in Chicago? Get Help Fast

A septic backup does not wait for a convenient time. Maybe sewage is coming up through a drain in your Chicago home, an alarm is sounding on your pump tank, or wastewater is pooling in the yard. The first goal is to stop adding water and get a septic company on the way.

Request a call and a company that serves Chicago and Cicero, Stickney, Berwyn will call you back to find out what is happening and when a crew can get there.

Limit the damage while you wait

The fastest way to limit damage is to stop adding water. If sewage has reached a floor, keep people out of the area, open windows for air and avoid using fans that spread odors through the house. Take photos for your insurance company before cleanup starts, then call a septic company.

What usually sets off an emergency

Most septic emergencies start quietly. A tank goes years without pumping, wipes and grease collect in the outlet, or roots slowly fill a line. Then a holiday with guests, a week of laundry or a storm pushes the system past its limit and the water has nowhere to go but back into the house.

When the septic alarm sounds

A high water alarm means water in the pump tank or aerobic unit has risen above normal. Press the silence button, cut back on water and check whether the breaker for the pump has tripped. If the alarm comes back on or the breaker trips again, call for service, because the pump may have failed.

Finding the real problem

A careful technician works from the house outward: the line to the tank, the tank itself, the outlet and filter, any pump chamber, then the distribution box and drain field. A camera may be used to look inside pipes. Knowing exactly where the failure is keeps you from paying for work that does not solve the problem.

Avoiding another septic emergency

Regular pumping, an effluent filter cleaned at each visit, and care about what goes down the drains prevent most emergencies. Fix leaking toilets and faucets, keep roof water away from the tank and field, and know where your tank lid is so a crew can reach it quickly if something does go wrong.

What to ask an emergency septic company

Ask when they can be there and what the trip will cost, including any after-hours or weekend fee. Ask if they will pump the tank and look for the cause on the same visit, and whether they can handle a repair if one is needed. Confirm they serve your address before they head out.

While you wait for help in Chicago

If sewage is backing up in a Chicago home, stop using water right away. Do not run the washer, dishwasher or showers. Keep children and pets away from any wet area in the yard. Open windows for air if there is an odor indoors, and have the tank lid location ready for the crew.

Local conditions behind septic emergencies in Chicago

Most mapped soils near Chicago are rated very limited for septic absorption, so a drain field that is already working hard can back up quickly when something else goes wrong. May is usually the wettest month in Chicago, and backups tend to rise when the ground stays soaked. About 2 months below freezing each year also bring the risk of frozen lines, especially in shallow pipes or homes left empty.

Local conditions in Chicago that affect emergency septic service

Among the mapped soils within about two miles of central Chicago, the USDA soil survey rates 100% as very limited for septic absorption fields, 0% as somewhat limited and 0% as not limited. The most common drainage class is moderately well drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.

Chicago averages about 39 inches of precipitation a year, and May is usually the wettest month. Average temperatures stay below freezing for about 2 months a year, with January averaging 27°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.

What the soil around Chicago means for emergency septic service
