Preventative Septic Maintenance & Repair in Boulder

This includes checking sludge levels, inspecting pipes for leaks or damage and advising on proper septic system care suited to the climate and usage patterns common in Boulder.
Septic Baffle and Tee Repair in Boulder
Baffles and tees keep scum and solids in the tank so they do not flow out into the leach field. Concrete baffles crumble from hydrogen sulfide gas, and plastic tees can break off. When they fail, solids clog the field fast. We replace damaged baffles with durable PVC tees and add an effluent filter where appropriate.

Alternative Septic System Repair in Boulder, CO
Some properties use aerobic treatment units or other alternative systems because of soil or lot size limits. These systems have air pumps, timers and alarms that need routine service. We repair aerators, replace diffusers and troubleshoot control panels. We also help keep maintenance records required by your permit.

If your septic alarm is sounding in Boulder, it is a clear sign of trouble.

Frequently Asked Questions About Septic Tank Repair in Boulder
Common repairs such as baffle replacement run $300 to $900, and effluent pump replacement typically costs $900 to $2,000. Leach field work can range from $5,000 to $20,000 or more. We provide a fixed price after inspection.
GFR Plumbing services and repairs all major septic tank brands and types, including concrete, fiberglass and plastic tanks and components from manufacturers like Infiltrator Systems, Presby Environmental and Advanced Drainage Systems. Our technicians are experienced with various septic system designs, from conventional gravity systems to aerobic treatment units.
Watch for slow drains, gurgling pipes, sewage odors, high water alarms, wet spots over the field or sewage backing up into tubs. Any of these calls for a prompt inspection.
To extend your septic system's life, keep up regular pumping every 3 to 5 years, avoid flushing non-biodegradable items, minimize harsh chemical use, conserve water and keep vehicles off the drain field. Regular inspections by GFR Plumbing can also catch small issues before they become bigger problems.
Minor repairs like replacing a tee or pump usually do not. Tank replacement, field replacement or system changes usually require a permit from the local health authority, and we take care of the coordination.
Typical signs include sewage odors around the tank or drain field, slow drains or backed-up toilets, lush green patches of grass over the drain field, gurgling sounds from pipes and standing water in your yard. If you notice any of these, call GFR Plumbing right away.
Soil type has a major effect on septic system performance. Basements are common in Colorado, and shifting soil can crack floor drains, sewer lines, and basement walls over time. Clay soils drain slowly, making drain fields more prone to failure, while very sandy or rocky ground can pass effluent too quickly. Our plumbers understand these local soil challenges.
Yes. Our workmanship is warrantied and new pumps, alarms and components carry manufacturer warranties. Terms are listed on your invoice.
