Frequently Asked Questions

What's the difference between septic tank repair and septic system repair?

Septic tank repair focuses on the tank itself. Septic system repair addresses the entire system, including the drain field, distribution box, pipes, and pump. System-level repairs require permits and must be performed by licensed contractors under NYSDOH standards (10 NYCRR Part 75) and your local board of health's permitting oversight.

How long does a septic system last before needing major repairs in New York?

A well-maintained septic system typically lasts 25-30 years. In New York, certain Long Island, New York City watershed, and other state-designated source-water protection areas must meet additional standards due to aquifer protection requirements. Coastal and high water table areas may see shorter drain field lifespans.

What causes septic drain field failure?

Common causes include lack of regular pumping (solids clog the drain field), excessive water use, flushing non-degradable items, parking vehicles on the field, and planting trees too close. High water tables in some areas and certain soil types make drain field failures more common.

Can a failed drain field be repaired or must it be replaced?

Sometimes drain fields can be restored through aeration or resting the field. However, severely failed fields typically need replacement, which requires a new site evaluation, soil test, and permit from your local board of health. Replacement can be significantly more complex and expensive due to lot size constraints in dense areas.
