Inspect Septic Tank Water Levels and Baffle Filter — Observe Effluent Discharge (if possible)
Part of project
Septic System Inspection · Step 7 of 9
In this video
Begin by safely locating and accessing the inspection points for your septic tank's drain field, which typically involves uncovering a lid. The video demonstrates two key observations. First, observe the water level at the exit pipe that leads from the septic tank to the drain field. For a drain field to be functioning properly, the water level should visibly remain *below* this exit pipe. This indicates that effluent is successfully being absorbed by the drain field. Second, locate the sanitary tee, also referred to as a baffle filter, on the other side of the tank (this is where effluent enters the drain field system). The water level should be *at* the level of this sanitary tee and should not rise *above* it. Additionally, visually confirm that the baffle filter itself is not clogged with solids or debris. If both conditions are met—the water level is below the exit pipe and at the baffle filter without any signs of clogging—then your septic tank drain field is considered to be working correctly, allowing the treated wastewater to drain out and percolate effectively into the surrounding soil.
FAQs
What are the most important safety precautions when inspecting a septic tank?
Never enter the septic tank, as it contains dangerous gases and lacks oxygen. Always wear thick gloves and eye protection to prevent contact with wastewater. Use a sturdy pry bar for lifting heavy lids and ensure the area is well-ventilated during your inspection to disperse any accumulated gases.
What specific tools and materials are essential for a DIY septic inspection?
You'll need a shovel, like the Anvil digging shovel, to excavate the lid and a pry bar set, such as the Husky 3-piece set, to open it safely. A bright flashlight, like the Defiant 2000 Lumens LED, is crucial for internal inspection. Have replacement materials like an Everbilt riser cover or Tuf-Tite effluent filter on hand if needed.
What are the key signs of a problem I should look for inside the septic tank?
Observe the scum (top) and sludge (bottom) layers; if they are excessively thick, your tank likely needs pumping soon. Check the inlet and outlet baffles for blockages, and look for any visible cracks or leaks in the tank walls. Excessive solids in the effluent filter also indicate an issue.
What's a common mistake beginners make during a septic inspection?
A frequent mistake is not properly securing or replacing the septic tank lid, which creates a serious fall hazard. Another common error is attempting to physically clear blockages or make repairs inside the tank without proper knowledge or equipment, which can be dangerous and cause further damage.
