How to Install Drain Field Chambers: A Step-by-Step Guide to Transform Your Drainage System

Drain field chambers are essential components of septic systems, designed to disperse wastewater into the surrounding soil. Installing them correctly is crucial for the efficient functioning of your septic system. Follow this comprehensive guide to learn how to install drain field chambers like a pro.

Materials You’ll Need

• Drain field chambers
• Level
• Measuring tape
• Shovel
• Gravel
• Fabric underlayment

Step 1: Determine the Location

Choose a location for the drain field that is at least 10 feet away from any water source. The area should be level or gently sloping to ensure proper drainage.

Step 2: Excavate the Trench

Dig a trench that is 24 inches wide and 12 inches deep. The length of the trench will depend on the size of the drain field.

Step 3: Level the Bottom of the Trench

Use a level to ensure that the bottom of the trench is level. This will help prevent the chambers from settling unevenly.

Step 4: Install the Fabric Underlayment

Lay a layer of fabric underlayment over the bottom of the trench. This will help prevent soil from clogging the chambers.

Step 5: Place the Drain Field Chambers

Set the drain field chambers in the trench, making sure that they are level and aligned properly. Leave a gap of about 1 inch between each chamber.

Step 6: Backfill with Gravel

Fill the trench around the chambers with gravel. The gravel should be 1-2 inches in size.

Step 7: Cover the Chambers

Place a layer of fabric underlayment over the gravel. This will help prevent soil from getting into the chambers.

Step 8: Backfill the Trench

Fill the trench with soil and tamp it down to compact it.

Step 9: Connect the Chambers

Connect the drain field chambers to the septic tank using perforated pipes. The pipes should be sloped downward to ensure proper drainage.

Troubleshooting Tips

• Chambers settling unevenly: Check the level of the trench and make sure that the bottom is level.
• Water pooling around the chambers: This could indicate that the trench is not draining properly. Check the slope of the trench and make sure that the pipes are connected correctly.
• Odors coming from the drain field: This could be a sign of a clogged drain field. Inspect the chambers and pipes for any blockages.

Conclusion

Installing drain field chambers is a straightforward process that can be completed in a few hours. By following these steps carefully, you can ensure that your septic system functions properly for years to come.
