Many cesspool problems can be repaired without full replacement. Cracked walls, damaged baffles, or inlet/outlet pipe issues are often repairable and much less expensive than replacement.
However, severely deteriorated tanks, major structural damage, or systems that consistently fail may need replacement. The age of your cesspool, extent of damage, and local soil conditions all factor into this decision.
A thorough inspection can determine whether repair or replacement makes more sense for your situation. Under new Suffolk County regulations, any cesspool replacement must include a septic tank, not another cesspool.
