How To Tell If Your Septic Tank Is Full – A Must-read For Every Homeowner!

If you’re experiencing plumbing issues, it’s essential to check if your septic tank is full. A full septic tank can lead to backups, overflows, and unpleasant odors. Here’s a comprehensive guide to help you determine if your septic tank is full and what steps to take to resolve the issue.

Signs of a Full Septic Tank

• Slow Draining Drains: Water takes longer to drain from sinks, showers, and toilets.
• Gurgling Noises: You may hear gurgling sounds from drains or toilets when water is flushed.
• Sewage Backup: Wastewater may back up into sinks, toilets, or showers.
• Overflowing Effluent Filter: The effluent filter, located in the septic tank outlet pipe, may overflow with wastewater.
• Pool of Sewage near the Tank: Sewage may seep out of the ground near the septic tank.
• Strong Odor: A foul odor may be present around the septic tank or in the home.

How to Check Septic Tank Level

1. Locate the Inspection Port: Find the access cover on top of the septic tank, usually marked with “Septic Tank.”

2. Remove the Cover: Carefully remove the access cover using a screwdriver or crowbar.

3. Measure the Sludge Layer: Insert a long stick or rod into the tank and measure the distance from the surface of the liquid to the top of the sludge layer.

4. Check the Scum Layer: Measure the distance from the surface of the liquid to the top of the scum layer, which floats on the liquid.

5. Determine the Liquid Level: Subtract the sludge layer depth and scum layer depth from the total depth to get the liquid level.

6. Compare to Tank Capacity: The liquid level should be at least 6 inches below the outlet pipe. If it’s higher, the tank may be full.

Troubleshooting a Full Septic Tank

1. Pump the Tank: Contact a septic tank pumping service to have the tank emptied.

2. Check for Leaks: Inspect the septic tank and pipes for any leaks that may be allowing water to enter and fill the tank.

3. Reduce Water Usage: Conserve water to reduce the amount of wastewater entering the tank.

4. Use Bacteria Additives: Add bacteria additives to the tank to break down solids and reduce sludge buildup.

5. Inspect the Drain Field: Ensure the drain field is functioning properly and not clogged.

Prevention Tips

• Regular Pumping: Schedule regular septic tank pumping every 3-5 years to prevent backups.
• Proper Disposal of Wastewater: Avoid flushing non-biodegradable items, such as wipes, diapers, and feminine hygiene products.
• Water Conservation: Install low-flow appliances and fixtures to reduce water usage.
• Septic Tank Maintenance: Inspect the tank and drain field annually for any issues.

Replacing a Septic Tank

If the septic tank is beyond repair or too small for your needs, you may need to replace it.

1. Contact a Professional: Hire a licensed septic tank installer to assess the situation and recommend the best course of action.

2. Get Permits: Obtain necessary building permits from the local authority.

3. Excavation and Installation: The old tank will be removed, and a new tank will be installed.

4. Drain Field Inspection: The drain field will be inspected and replaced if necessary.

5. Backfill and Grading: The excavated area will be backfilled and graded to ensure proper drainage.

Final Note

Checking your septic tank regularly is crucial to maintain a healthy plumbing system. By following these steps, you can determine if your septic tank is full and take appropriate action to resolve the issue. Remember, a well-maintained septic tank is essential for a comfortable and odor-free home environment.
