Septic System Do’s and Don’ts

Keeping your septic system healthy isn’t just about regular maintenance; it’s about being a
diligent “gatekeeper” for what goes down your drains. Unlike a city sewer system, a septic tank
is a delicate living ecosystem of bacteria that breaks down waste. When you flush the wrong
items, you risk expensive backups, system failure, and environmental contamination.
Based on the expertise of local professionals like AJ Liquid Waste Haulers, here is a guide on
what to keep out of your pipes.

1. “Flushable” Wipes and Paper Products

The biggest myth in modern plumbing is the “flushable” wipe. While they may clear your toilet
bowl, they do not break down in the tank.
● Baby Wipes & Cleaning Wipes: These are often made of synthetic fibers that remain
intact for years, quickly filling up your tank or clogging the inlet pipe.
● Paper Towels & Tissues: These are designed to be absorbent and strong when wet, unlike
toilet paper, which is engineered to dissolve.
● Feminine Hygiene Products: Pads and tampons are designed to absorb liquid and
expand—the exact opposite of what you want in a septic pipe.

2. Fats, Oils, and Grease (FOG)

It might be liquid when it’s hot in the pan, but once it hits your cool underground pipes, it
solidifies.
● The “Scum” Layer: Grease contributes to the upper layer of your tank. If this layer
becomes too thick, it can flow into the drainfield, plugging the soil and leading to a total
system failure.
● Alternative: Always scrape pans into the trash or a dedicated grease jar.

3. Household Chemicals and Medications

Your septic tank relies on anaerobic bacteria to digest solids. Heavy chemicals act like a
poison to these beneficial microbes.
● Bleach & Harsh Cleaners: Using small amounts for laundry is usually fine, but “shocking”
your system with large quantities of drain cleaner or bleach can kill the bacterial colony.
● Antibiotics & Pharmaceuticals: Flushing unused meds sends them directly into the
groundwater. Furthermore, antibiotics are literally designed to kill bacteria—the very thing
your tank needs to function.
● Paint & Solvents: Never rinse latex or oil-based paint tools in a sink connected to a septic
system.

4. Food Scraps and Garbage Disposals

While many homes have garbage disposals, they are generally discouraged for septic owners.

● Solid Buildup: Disposals grind food into fine particles that don’t always break down easily.
This increases the “sludge” at the bottom of the tank, requiring you to call for septic
pumping much more frequently.
● Coffee Grounds: These are notorious for never breaking down and settling into the nooks
and crannies of your plumbing.

5. Non-Biodegradable “Toxics”

If it’s not biodegradable, it stays in the tank until a professional pumps it out.
● Cigarette Butts: These contain plastic filters and chemicals that linger indefinitely.
● Cat Litter: Even “flushable” clay or pine litters can harden like concrete in your pipes or add
an unmanageable amount of solid waste to the system.
● Condoms: Made of latex or polyurethane, these will never break down and can easily snag
on pipe burrs, causing immediate clogs.

Pro-Tip: The “Golden Rule” of Septic Systems

The only things that should ever be flushed are human waste and septic-safe toilet paper.
If you suspect your tank is getting full or you’ve accidentally flushed something you shouldn’t
have, it’s best to consult a professional. AJ Liquid Waste Haulers provides residential pumping
and inspections to ensure your system stays in peak condition.
