5 signs your septic system needs repair

Septic systems are designed to run quietly for decades, and most of the time they do. But when a component wears out or something shifts underground, the system sends signals before it fails completely. Catching those signals early is the difference between a repair bill and a full system replacement.

Slow drains throughout the house

A single slow drain is almost always a local clog in the pipe between the fixture and the main line. When every drain in the house slows down at the same time, the problem is downstream. Either the tank is full and needs pumping, or the outlet from the tank to the drain field is blocked. A pump-out is the first step in diagnosis: if the tank fills back up within days of being pumped, the drain field is not accepting effluent, and that is a repair, not a maintenance issue.

Sewage odors in the yard or near the tank

A properly functioning septic system should produce no detectable odor above ground. If you smell sewage near the tank, the access lid may not be sealed properly, or the tank's venting is inadequate. If the odor is coming from the drain field area, effluent may be rising closer to the surface than it should. Both situations point to components that need inspection.

The pump alarm keeps going off

Systems with a pump chamber (most modern installations in areas with clay soil or high water tables) have an alarm that sounds when the water level in the pump chamber rises above normal. The alarm means the pump is not moving effluent out of the chamber at the rate it is coming in. The pump itself may have failed, the float switch that controls it may be stuck, or the breaker that powers it may have tripped. If resetting the breaker does not silence the alarm within a few hours, the pump or float needs repair.

Standing water over the drain field

Water pooling on the surface above the drain field, especially when it has not rained recently, means the soil can no longer absorb the effluent the system is sending it. This can happen when the drain field is saturated from years of use, when roots from nearby trees have crushed or clogged the distribution pipes, or when the biomat layer at the bottom of the trenches has grown too thick. A saturated drain field is the most serious sign on this list, because it usually means the field itself needs repair or replacement, not just a single component.

Unusually green patches of grass

Grass over a healthy drain field should look about the same as the rest of the lawn. A strip or patch of grass that is noticeably greener and taller than its surroundings is being fertilized by effluent that is closer to the surface than it should be. It is the same problem as standing water, just at an earlier stage. Left alone, the green patch turns into a wet patch.

What to do when you notice any of these

Start by reducing water use in the house: shorter showers, no laundry, no dishwasher. This buys time while the system is assessed. Then call for an inspection.
