Septic Baffle and Tee Repair in Denver
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 it makes sense.

Common causes of septic tank failure include improper waste disposal, such as flushing non-biodegradable items, lack of regular pumping, tree root intrusion, heavy vehicle traffic over the drain field and poor soil drainage. Septic systems and private wells are common in the mountains and rural plains of Colorado, outside the reach of municipal sewer.
Key signs include slow drains, gurgling toilets, sewage odors inside or outside your home, oddly lush or soggy spots in your yard near the septic tank or drain field, and sewage backups into your home. If you notice any of these, it is important to call GFR Plumbing promptly to prevent further damage.
Common causes of septic tank failure include infrequent pumping, which lets solids accumulate, tree root intrusion into pipes or the tank, excessive water usage overloading the system, driving heavy vehicles over the drain field and using harsh chemicals that kill beneficial bacteria. Dense, clay-rich soils can also add to drain field issues.
We install effluent pumps from Zoeller, Liberty, Goulds and similar quality brands, along with matched float switches and alarm panels.
