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.

How fast can someone come out in Mendota?

Response time depends on the company's schedule and where you are. Tell them it is an emergency and describe what you see so they can prioritize and bring the right equipment.

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

Septic Backup or Alarm in Mendota? Get Help Fast

Septic emergencies usually show up as a backup in the lowest drain, a sewage smell that will not go away or a high water alarm. Each of these means wastewater has nowhere to go, and it will only get worse with more water use.

Use the form or call to reach a local septic company working in Mendota. Tell them what you are seeing so they can bring the right equipment on the first trip.

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.

If your septic alarm is going off

An alarm on a pump chamber or aerobic unit usually means the water level is too high. Many alarms have a silence button; press it, then cut back on water use. Check that the pump's breaker has not tripped. If the alarm comes back on after a few hours, the pump, float switch or control panel may have failed and needs service. Do not open the pump chamber yourself, since it contains wastewater and electrical equipment.

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.

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.

Common septic emergencies near Mendota

Most urgent septic calls near Mendota come from a full tank, a failed pump or alarm, or a blocked line between the house and the tank. Heavy rain can make any of these worse. A crew can usually tell which one it is within minutes of opening the tank.
