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

Emergency Septic Service in Wilmington, DE

A septic backup does not wait for a convenient time. Maybe sewage is coming up through a drain in your Wilmington 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 Wilmington and Bellefonte, Elsmere, Penns Grove will call you back to find out what is happening and when a crew can get there.

First steps during a septic backup

Turn off anything that uses water, including the washer and irrigation. If a toilet or floor drain is overflowing, do not keep flushing to try to clear it. Keep people and pets away from any sewage and wash hands well if you come in contact with it. Check whether the problem is in one fixture or the whole house, since that helps the company tell a clogged line from a full tank.

Why septic systems back up

Backups usually happen because the tank is full, the pipe from the house is blocked, or the drain field has stopped accepting water. A failed pump in a pump chamber, a broken baffle that let solids into the outlet, and heavy rain that saturates the yard are other common triggers for an emergency call.

High water alarms explained

A high water alarm tells you wastewater is rising above where it should be in a pump or treatment tank. The cause might be a stuck float, a failed pump, a tripped breaker or more water coming in than the system can handle. Silencing the alarm is fine, but the underlying problem still needs attention. Tell the septic company what type of system you have and the brand on the control panel if you can see it.

What to expect when the truck arrives

Expect the technician to start at the tank, not inside the house. Pumping usually relieves the backup right away, and the crew will then look for the cause: a clog, a broken part or a field that is no longer draining. Ask them to explain what they found before any larger repair is scheduled.

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.

Choosing help in an emergency

Even in a hurry, a few questions are worth asking. Is the company licensed where you live and insured? Will they explain the cause before recommending major work? Do they handle repairs and replacements, or only pumping? the New Castle County health department can confirm whether a permit is needed for repairs in Wilmington.

After an urgent septic call in Wilmington

Once the emergency is handled, ask the Wilmington crew what caused it and what would prevent a repeat. The answer might be a pumping schedule, a new pump or float, or a repair to a line. Clean any affected area inside the home with disinfectant and keep the invoice with your records.

Local conditions behind septic emergencies in Wilmington

Most mapped soils near Wilmington 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. About 47 inches of precipitation a year means saturated ground is common, and backups often follow long stretches of rain. About 1 months below freezing each year also bring the risk of frozen lines, especially in shallow pipes or homes left empty.

Local conditions in Wilmington that affect emergency septic service

Among the mapped soils within about two miles of central Wilmington, the USDA soil survey rates 79% as very limited for septic absorption fields, 19% as somewhat limited and 2% as not limited. The most common drainage class is 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.

Wilmington averages about 47 inches of precipitation a year, and June is usually the wettest month. Average temperatures stay below freezing for about 1 month a year, with January averaging 32°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
