Why Is My Septic System Leaking?

Various issues can cause a septic system to leak, and improper maintenance can make septic issues far more likely. You can reduce the chances of your septic system leaking by scheduling an inspection and pumping it every three to five years.

Other reasons for a septic system leaking can be harder to avoid, even with the most rigorous maintenance schedule. Here are some of the most common causes:

Tree Roots

Over time, tree roots can infiltrate your septic tank or drain field. Roots that clog your drain field prevent the tank from draining correctly, causing it to overfill and spring leaks. If the roots grow into the tank itself, the tank will develop cracks and allow unfiltered sewage to seep into the surrounding area.

Clogs

If you don't have your septic system pumped regularly, solids can block the pipes and increase the risk of leaks. How often you need to have your septic system pumped depends on several factors, including the size of your system, how heavily you use it and the manufacturer. Your supplier can advise you on the most suitable servicing interval for your system.

Septic Field Pressure

Pressure on your drain field can compact the earth and lead to leaks. Heavy rainfall sometimes causes drain field compaction due to increased groundwater. Driving over your drain field can also cause excess pressure and damage, so keeping vehicles away from your septic system is crucial.

Flushing the Wrong Items

Your septic system is designed to deal with human waste and toilet tissue only. Flushing nondegradable items, such as diapers, facial wipes (even the "flushable" brands) and feminine hygiene products, increases the risk of clogs and leaks because your septic system can't break them down. Protect your system by placing garbage cans next to every toilet in your home and educating your family about which items can be safely flushed.

Cleaning Products

Certain cleaning products kill the bacteria that break down waste inside your septic system, potentially causing leaks and system failure. You can prevent this issue by using septic-friendly cleaners.

Why Are Septic Tank Leaks Hazardous?

A leaking septic system releases untreated sewage into the environment. Sewage contains potentially dangerous pathogens, which can cause illness in humans and animals.

Sewage leaks aren't just hazardous to your family and pets. Unprocessed sewage can also contaminate waterways, introducing germs into the water used for drinking, swimming and farming.

What Should You Do if You Suspect a Septic Leak?

Knowing the signs of a septic system leak allows you to spot and repair problems quickly before they pollute your living environment. Common warning signs include:

• Foul-smelling water backing up into your toilets, bathtubs and other plumbing fixtures

• Water accumulating on the ground surrounding your septic tank or leach field

• Slow drainage

• Unpleasant smells in the areas around your septic system

• Unusually lush or green grass over your leach field

• Unusual noises coming from your plumbing

You should hire a licensed septic system technician to inspect your system as soon as you suspect a leak. A septic professional can diagnose the problem and perform repairs to get your system running smoothly and prevent further contamination. If the wastewater has damaged your house or backyard, you may also require water damage remediation services.

While waiting for your septic system inspector to arrive, avoid flushing water down your drains as much as possible. Minimizing the use of your plumbing system helps you avoid overloading your septic tank and stops the leak from worsening. It's also worth closely monitoring the area around your septic system and telling your inspector about any changes to help them diagnose the problem more accurately.
