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

Septic Backup or Alarm in Lafayette? 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 Lafayette. 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.

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.

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.

A septic backup in Contra Costa County

If a backup happens in Contra Costa County, the first priority is keeping sewage out of living space and away from people. After that, a pumper can relieve the tank and find the cause. If the drain field turns out to be failing, the Contra Costa County health department may need to be involved in the repair.
