Whether or not it’s hard to pass a perc test depends a lot on the composition of your soil. When a perc test is conducted where there’s a high concentration of sand in the soil, perc tests almost always pass. However, if your ground is dense clay or rock, it may prove difficult to pass a perc test. A low water table also helps you pass the test, as a high table means your yard isn’t draining water as efficiently.

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

A septic system's lifespan typically ranges from 15 to 40 years, with a common average of 20 to 30 years. The longevity heavily depends on the tank's material, maintenance diligence, and usage habits. With proper care, lifespans can reach the upper end of this range.

Lifespan by Tank Material:

• Concrete: 20 to 40 years

• Plastic or Fiberglass: 30 to 40 years

• Steel: 15 to 20 years

To maximize your system's lifespan, follow these maintenance best practices:

• Regular Pumping and Inspections: Have the tank pumped every three to five years and schedule professional inspections regularly.

• Mindful Usage: Only flush human waste and toilet paper. Avoid putting items like cat litter, paper towels, cigarette butts, fats, grease, oils, or coffee grounds down your drains.

• Avoid Chemicals: Do not pour harsh chemicals into the system.

• Water Conservation: Reduce the amount of wastewater your system has to process.

• Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

A septic system can fail for various reasons, and most commonly, excessive water use or sudden surges in wastewater can overwhelm the system's capacity. Neglecting regular maintenance, like tank pumping and inspections, can also lead to clogs, leaks, and eventual breakdowns. Other issues that lead to failure include age-related wear and tear, root infiltration, improper disposal of non-biodegradable materials or chemicals into the system, unsuitable soil conditions, physical damage, and even environmental factors like flooding or soil erosion.
