Septic Questions,
Straight Answers

The questions we hear most from neighbors around Yucaipa, Redlands, and the Inland Empire — answered plainly by a family that's been doing this work since 1950.

How often should I pump my septic tank in Yucaipa or Redlands?

For most Inland Empire homes with a 1,000-gallon tank and a family of four, every 2–3 years is typical. Larger tanks or smaller households can stretch longer, but we recommend an inspection at least every 3–5 years regardless — garbage disposals, guests, and heavy laundry fill tanks faster than the averages predict. Try our pump-out frequency calculator for your setup, or call us for routine or emergency pump-outs 7 days a week.

What are the signs my septic system is failing?

Slow drains throughout the house, gurgling pipes, sewage odors indoors or in the yard, unusually green or soggy grass over the leach field, and sewage backing up into the lowest drains. If you notice any of these, ease off heavy water use and call a licensed septic contractor promptly — early repairs are far cheaper than a failed system.

What is a PERC test, and do I need one to build in San Bernardino County?

A percolation (PERC) test measures how quickly your soil absorbs water — it determines whether the property can support a septic system and how large the leach field must be. San Bernardino and Riverside counties generally require PERC or soil-profile testing before permitting a new system on unsewered land. We perform the testing, soil profiles, and county paperwork in-house.

What size septic tank does my house need?

In California, tank size is driven by bedroom count, not occupants. Common county minimums: 1,000 gallons up to 3 bedrooms, 1,200 at 4 bedrooms, 1,500 at 5–6 bedrooms — some counties require larger. A garbage disposal or heavy water use typically bumps the recommendation up one size. Our tank size calculator gives you a ballpark, and we confirm the exact requirement with your county before any install.

How long does a septic system installation take?

Once permits are approved, a standard residential install is usually a few days of site work. The full timeline — soil testing, engineered design, county permitting — typically runs several weeks. Because our engineering department is in-house and we pull the permits ourselves, plans are usually approved the first time, which keeps the schedule short.

What's the difference between leach lines and a seepage pit?

Leach lines are shallow horizontal trenches that spread treated wastewater over a wide area of soil. A seepage pit is a deep drilled shaft used where lot size or soil conditions make leach lines impractical. Soil type, groundwater depth, available space, and county rules decide which your property needs — a PERC test and site evaluation give the answer.

What is an aerobic treatment unit (ATU), and when is one required?

An ATU is an advanced septic system that uses oxygen and multiple treatment stages to clean wastewater to a higher standard than a conventional tank. Counties often require them on tight lots, properties with high groundwater, poor-draining soils, or sites near sensitive water sources. We design, install, and service ATUs across the Inland Empire.

Do I need a septic inspection when buying or selling a home?

In most Inland Empire transactions on septic, yes — lenders, buyers, or the county commonly require an inspection and certification before close of escrow. It typically includes locating and opening the tank, checking levels and components, and often pumping. We handle real-estate and county inspections with the certification paperwork done right.

Can I convert my property from septic to public sewer?

If a public sewer main runs near your property, conversion is usually possible — and sometimes required when a septic system fails. The job involves permits, trenching, the tap and tie-in to the main, inspection, and proper abandonment of the old tank. We handle septic-to-sewer conversions start to finish.

Who is the best septic company near Yucaipa and Redlands?

Look for a California C-42 licensed contractor with local experience, its own equipment, and clear upfront pricing. Valley Drilling Co has served Yucaipa, Redlands, and the Inland Empire since 1950 — family-owned for three generations, C-42 licensed, bonded and insured, with an in-house engineering department and phones answered 7 days a week.
