Everyday habits that protect your system

Your septic system handles everything that goes down the drains in your Sunnyside home. Using less water, spacing out loads of laundry and skipping the garbage disposal all reduce the load. Keep the area over the drain field planted in grass, and know where your tank lid is so pumping visits are quick. Records of past service make future repairs and home sales easier.

Signs your system needs attention

Septic problems tend to show up gradually. Listen for gurgling pipes, watch for slow drains in more than one fixture, and check the yard for standing water or a sewer smell after heavy water use. If an alarm sounds on a pump or aerobic system, cut back on water and call for service rather than silencing it and waiting.

Questions Sunnyside homeowners should ask first

Before hiring in Sunnyside, ask three things. Are you licensed and insured for septic work in Yakima County? Will you inspect the baffles and filter when you pump? Can you show me what you found? Clear answers tell you more than a low quote does.

Records worth keeping for your Sunnyside septic system

Keep a simple file for your Sunnyside septic system. Include the permit and as-built drawing if you have them, each pumping receipt, and notes on any repairs. Inspectors, buyers and future septic companies all ask for this history. It also helps you spot when the pumping interval is getting shorter, which is an early warning.

Local conditions in Sunnyside

Among the mapped soils within about two miles of central Sunnyside, the USDA soil survey rates 54% as very limited for septic absorption fields, 42% as somewhat limited and 4% as not limited. The most common drainage class is well drained. Conditions vary from lot to lot here, so a site evaluation is the only way to know how well a particular yard will handle a drain field.

Sunnyside averages about 11 inches of precipitation a year, and December is usually the wettest month. Average temperatures stay below freezing for about 2 months a year, with December averaging 31°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
