Can I flush flushable wipes with a septic system?

No. Despite the label, so-called flushable wipes do not break down like toilet paper and can build up in the tank and clog pipes and baffles. Only human waste and toilet paper should be flushed on a septic system.

What are the signs my septic tank is full or failing?

Common warning signs include slow drains throughout the house, gurgling plumbing, sewage odors, and unusually lush or wet patches over the drain field. A backup into the house is often the clearest warning.

Is the pumping calculator accurate?

Your Septic System Doesn't Have to Be a Mystery.

Q: How often should a septic tank be pumped?

The U.S. EPA advises homeowners to have a typical household septic system inspected about every three years and the tank pumped every three to five years, depending on household size, tank size, and water use. Use the calculator on this page for an estimate specific to your system.

Q: How much does septic tank pumping cost?

Pump-out cost varies widely by region, tank size, and access. It is a modest, planned expense compared with repairing or replacing a failed drain field. Use the calculator on this page for an estimated regional range.

Q: Do septic additives work?

A healthy septic tank already contains the bacteria it needs. Regular pumping and sensible water use, not additives, are what keep a system working, and some additives can even harm the system.

A Neglected Tank Is a Quiet, Expensive Problem.

Your septic tank works by letting solids settle. Grease and light material float up into the scum layer; heavier solids sink into the sludge layer; only the clarified middle, the effluent , should ever leave the tank for the drain field.

Skip pump-outs for too long and that sludge builds until solids start pushing past the baffle and into the drain field. Once the drain field clogs, you're into repair or replacement territory, and a backup into the house is often the first warning.

The EPA advises homeowners to have a typical system inspected about every three years and the tank pumped every three to five years, depending on household size, tank size, and use.

How much does septic tank pumping cost?+

It varies widely by region, tank size, and access, so we won't quote one figure as fact. A routine pump-out is a modest, planned expense; a failed drain field is far costlier. Use the calculator for an estimated regional range.

No. Despite the label, they don't break down like toilet paper and can accumulate in the tank and snag on baffles. Only human waste and toilet paper should go down the toilet.

Slow drains across the house, gurgling pipes, sewage odors, and soggy or unusually green patches over the drain field are common signals. A backup indoors is the loudest warning.
