Having issues with a clogged or slow-draining septic line can be a nightmare. Calling a professional plumber to snake the line can be expensive and time consuming. Luckily, snaking a septic line is a DIY project that can be done relatively easily without any professional help. With some simple tools, patience, and the right technique, you can unclog your septic line on your own.
What Causes Clogs in Septic Lines?
Knowing what causes clogs in the first place can help you better understand how to fix them. Here are some of the most common culprits of septic line clogs:
-
Excess waste buildup - Grease, oil, food scraps, feminine hygiene products, and other solid materials can accumulate over time and cause major blockages.
-
Tree roots - Roots from nearby trees can make their way into pipes and joints, growing over time and disrupting flow.
-
Improper drainage - If wastewater cannot drain properly, it can back up and cause clogging issues.
-
Pipe damage - Cracks, leaks, or misaligned pipes allow solids to get stuck and accumulate.
-
Improper system maintenance - Not pumping the septic tank regularly can lead to excess solids entering the leach field lines.
Gather the Proper Septic Snaking Tools
Snaking a septic line requires only a few key tools:
-
Drain auger/snake - This is the most important tool. A hand crank or drill-powered auger can clear blockages. Get one at least 3/4" wide x 25' long.
-
Protective gloves - Wear thick rubber gloves to protect your hands.
-
Bucket - Use a 5-gallon bucket to collect any wastewater or debris as you work.
-
Flashlight - Seeing into the drain pipe is crucial, so have a bright flashlight on hand.
-
Wrenches - You may need wrenches to remove cleanout covers before snaking.
Locate the Cleanout
The septic line cleanout is your access point for snaking. There should be a vertical, 4-6" PVC pipe near the septic tank with a removable cap. If the cleanout isn't obvious:
-
Check near the basement wall or external drain exits.
-
Look for a white PVC cap at ground level.
-
Refer to septic permit records for mapped locations.
-
Use a drain camera to identify cleanout locations.
Removing the cleanout cap gives you direct line access for snaking.
Snaking Tips and Techniques
Follow these tips when snaking your septic line:
Safety First
- Turn off power to any pumps before snaking to avoid electrical hazards.
- Never open the septic tank itself - dangerous gases can be released.
Take Your Time
-
Go slowly and steadily to effectively clear blockages. Rushing can damage pipes.
-
Make several gentle "push and pull" passes through troubled areas.
Look for the Source
-
Pinpoint where the clog begins, then focus efforts there until water starts flowing freely.
-
If one area seems clear, keep snaking further down the line to be sure.
Remove Roots Carefully
-
Use caution when snaking through roots to avoid damaging pipes.
-
Spin the auger head slowly and gently saw through roots rather than yanking.
Dispose of Debris
-
Collect any solid debris that comes up through the cleanout.
-
Bag it securely before disposing with regular household trash.
When to Call a Professional
While DIY septic snaking is ideal, there are times to call a pro:
-
If you can't locate or access the cleanout.
-
For widespread tree root intrusion. Roots may need hydrojetting.
-
If snaking efforts don't resolve clogging issues.
-
For septic tank pumping or repairs.
-
If you suspect collapsed, damaged, or leaking pipes.
Snaking a septic line on your own takes effort but saves money. With the right tools and methodical snaking approach, you can often clear clogs and get your system flowing freely again. Know when to call a pro for major septic repairs, but don't be afraid to DIY for routine maintenance.
