Is sewage in the house dangerous?

Sewage can carry bacteria and viruses. Keep people and pets away, wear gloves if you must touch anything, and clean affected areas thoroughly after the problem is fixed. Large spills may call for a professional cleanup company.

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

Emergency Septic Service in Merced, CA

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 Merced. 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.

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.

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.

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.

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 Merced County health department can confirm whether a permit is needed for repairs in Merced.

A septic backup in Merced County

If a backup happens in Merced 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 Merced County health department may need to be involved in the repair.
