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

Emergency Septic Service in Sonoma, CA

A septic backup does not wait for a convenient time. Maybe sewage is coming up through a drain in your Sonoma 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 Sonoma and Napa, Yountville, Petaluma 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 goes wrong

Most emergency calls in places like Sonoma trace back to a full tank, a clog, a pump failure or a saturated drain field. Systems that have not been pumped in many years are the most likely to fail suddenly, often after a busy weekend of guests or laundry. Older systems with clay pipes are more prone to root intrusion and cracks.

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.

How an emergency visit usually goes

The first priority is to get wastewater moving so you can use your plumbing again, which often means pumping the tank or clearing a line. Next the technician looks for the underlying cause. Some fixes happen on the spot, like replacing a float or cleaning a filter. Others, like replacing a drain field, need a follow-up visit, permits and a written estimate.

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.

After an urgent septic call in Sonoma

Once the emergency is handled, ask the Sonoma 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.

Among the mapped soils within about two miles of central Sonoma, the USDA soil survey rates 96% as very limited for septic absorption fields, 4% as somewhat limited and 0% as not limited. The most common drainage class is well drained.
