Aerobic Septic Service in Pasadena, CA

Aerobic treatment units clean wastewater with oxygen and bacteria before it leaves the system. They work well on lots where a conventional drain field would struggle, but they have moving parts that need regular service.

A septic company that services aerobic systems in Pasadena and San Marino, South Pasadena, La Cañada Flintridge can handle routine maintenance, alarms and repairs.

Why aerobic systems need air

The difference between an aerobic unit and a regular septic tank is oxygen. A small compressor pushes air into the treatment chamber around the clock, keeping oxygen-loving bacteria alive. If the air stops, those bacteria die off within days, odors build and poorly treated water reaches the yard, which is why a silent aerator is worth a call.

Maintenance visits explained

Expect the technician to confirm the aerator is running, clean filters and diffusers as needed, check floats and pumps, and inspect the disinfection unit. They will note when the pretreatment tank needs pumping. Many areas require these visits to be reported, so keep your records.

When your aerobic alarm goes off

First check the breaker for the system. If it has tripped and trips again after resetting, do not keep resetting it. Cut back on water use and schedule service. Tell the company the brand of your unit if you can find it, since parts differ between manufacturers.

How often to service an aerobic system

Many manufacturers and local rules call for service every few months, often two to four visits a year. The pretreatment tank still needs pumping periodically. the Los Angeles County health department or your state agency may set minimum requirements, so check what applies to your property in Pasadena.

Signs your aerobic system needs attention

Watch for a sewage or rotten egg smell, an aerator that is silent, cloudy or foul-smelling discharge, spray heads that do not run, and alarms. Soggy areas near the spray field can also point to a problem.

Questions to ask an aerobic service company

Ask whether they service your brand of unit, what each visit includes, how they handle required reporting and how quickly they respond to alarms. Ask whether parts and chlorine are included in a service plan.

Knowing your equipment

It helps to know the brand and model of your aerobic unit, where the control panel is, and whether your system uses spray heads or drip lines. Keep the manual and past service records together. When you call a company in Pasadena, that information lets them bring the right parts and finish the visit in one trip.

When to call right away

Call soon if the alarm sounds and does not stop after you check the breaker, or if the aerator is silent. A strong odor near the unit or the spray field is another reason to call. Treated water that looks gray or smells like sewage is a sign something needs attention in your Pasadena system.
