How We Repair Your Thomas Septic Aerator
Sump, well, booster and sewage ejector pumps and septic aerators keep water moving, and most failures happen when you need them most.
Thomas Septic Aerator models often use model-specific control boards, sensors and diagnostic modes. We look up your exact model number so the right part goes in the first time.
Common Septic Aerator Problems We Fix

A waterlogged pressure tank or a bad pressure switch.

A stuck float switch, a tripped breaker, a failed capacitor or a burned-out motor.

Should I repair or replace my septic aerator?
A septic aerator typically lasts about 7 to 15 years. If yours is well inside that range and the repair costs less than half the price of a new one, repairing usually makes sense. Near the end of its life, or when the repair costs more than half of a replacement, replacing is often the better value. We give you an honest opinion either way.
