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.

Why did my system back up after heavy rain?

Saturated soil can stop a drain field from absorbing water, and surface water can seep into tanks and lids. The system may recover as the ground dries, but repeated problems after rain point to a drain field or drainage issue that should be inspected.

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 Clackamas County health department, or ask the septic company to handle permits for you.

Septic Backup or Alarm in Lake Oswego? Get Help Fast

When a septic system fails suddenly, homeowners in Lake Oswego need two things: to keep the problem from spreading and to get a qualified crew on site. Most emergencies trace back to a full tank, a clogged line or a failed pump.

A local company that works across Clackamas County can find the cause, pump the tank if needed and get your plumbing working again.

What to do right now

Stop using water. That means no laundry, dishwasher, showers or flushing until the problem is found, because every gallon has to go somewhere. If sewage has come up into the house, keep children and pets away, avoid touching it without gloves and open windows for ventilation. If your system has a pump and an alarm, do not keep silencing and ignoring it. Note what you see, when it started and anything that changed recently, then call a septic company.

Common causes of septic emergencies

A tank that is overdue for pumping is the most common cause. Other frequent culprits include a clogged line between the house and the tank or a blocked outlet baffle or filter. A failed pump or a drain field that can no longer absorb water can also cause a sudden backup. Heavy rain can make a struggling drain field fail suddenly. Tree roots, crushed pipes and items like wipes or grease also cause blockages.

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.

What the septic company will do

Expect the crew to ask questions first, then locate the tank and check the water level. If the tank is full, they will pump it so the house can drain. With the tank open, they can see whether the outlet, filter or baffles are blocked, and whether water is flowing back from the drain field, which points to a field problem. For pump systems they will test the pump, float and panel. You should get a clear explanation of the cause and your options.

Preventing the next emergency

Most emergencies are preventable. Pump the tank on a regular schedule, have the effluent filter cleaned, and keep grease, wipes and chemicals out of the drains. Spread laundry across the week rather than doing many loads in one day. Keep vehicles and heavy equipment off the tank and drain field, and direct roof and yard drainage away from them. If you have a pump system, test the alarm now and then.

Questions to ask when you call

Ask how soon a crew can arrive and whether there is an extra charge for after-hours service. Ask whether they can pump and diagnose on the same trip. Confirm they work on your type of system, especially if you have a pump, aerobic unit or mound. After the visit, ask for a written summary of what failed, what was done and what still needs attention.
