Professional Septic System Repair in Harris County
When your septic system isn't working properly, you need a provider who can accurately diagnose the problem — not just treat the symptoms. Many septic issues have multiple potential causes, and misdiagnosis means paying for repairs that don't solve the real problem. Enviro-Pal's experience and technical credentials ensure we get to the root cause on the first visit.
We repair all types of on-site sewage facilities: conventional septic tanks, aerobic treatment units, drip irrigation systems, surface application systems, lift stations, and pump systems. Our technicians are equipped to service all major manufacturer brands.
Common Septic Repairs We Handle
Aerator and Compressor Replacement
The aerator is the heart of an aerobic treatment system. When it fails, the system stops treating waste effectively. Signs of aerator failure include the alarm sounding, bubbles stopping in the treatment chamber, or sewage odor from the system. We stock common aerator models and can often replace them the same day. Typical cost: $200 – $600 for the aerator plus installation.
Pump Repair and Replacement
Effluent pumps, dosing pumps, and transfer pumps move treated water from the tank to the disposal area. Pump failure causes the tank to fill up and eventually back up into the home. We diagnose whether the issue is the pump itself, the float switch, the control panel, or an electrical problem — because replacing a good pump when the real problem is a stuck float wastes your money.
Float Switch and Control Panel Issues
Float switches tell your system's pumps when to turn on and off. Control panels manage the sequencing of all electrical components. Both are prone to corrosion, insect damage (fire ants are notorious for nesting in control panels), and electrical surges. We troubleshoot the full electrical system before recommending component replacement.
Drainfield Problems
Drainfield issues range from minor (a clogged distribution line that can be jetted) to major (a fully saturated field that needs replacement). Signs include standing water over the drainfield, soggy ground, and sewage odor. We assess whether the drainfield can be rehabilitated or needs replacement — an honest evaluation that can save you thousands.
Tank Damage
Septic tanks can develop cracks, corroded baffles, damaged inlet/outlet tees, root intrusion, and structural shifts over time. Some tank damage can be repaired in place; other situations require tank replacement. We inspect the full tank interior to determine the most cost-effective approach.
Spray Head and Distribution Issues
Aerobic systems with surface application (spray heads) can develop clogged nozzles, broken risers, misaligned heads, and distribution problems. We check all spray heads against the original installation drawing to ensure proper coverage and code compliance.
Pipe and Line Repairs
Broken sewer lines between the house and tank, damaged distribution pipes, and crushed drainfield lines are common — especially in older systems or after ground movement, root intrusion, or heavy equipment driving over the system.
Emergency vs. Permitted Repairs
Under Texas law, emergency repairs do not require a permit but must be reported to the county permitting authority within 72 hours. Emergency repairs include replacing tank lids, inlet and outlet devices, repairing risers and riser caps, repairing or replacing disinfection devices, repairing damaged drip irrigation tubing, and repair of solid lines.
Non-emergency repairs — including tank replacement, drainfield replacement, and system alterations — require a permit from Harris County before work begins. We handle all permitting for non-emergency repairs as part of our service.
