Grinder Pump Education

Wipes Are Not Flushable. And Grinder Pumps Are Not Bulletproof.

If there's one thing we wish every homeowner understood, it's this: Just because something says "flushable" doesn't mean it belongs in your sewer system.

At Griffen Pump Service, we install and service industry-leading Liberty Pumps grinder pumps - but let's be honest:

These are engineered pumps, not billy goats.
They are designed to grind and move wastewater - not chew through wipes, rags, hygiene products, or anything else that shouldn't be in your system.

What Actually Happens When You Flush a "Flushable" Wipe

Toilet paper is engineered to break down quickly in water. That's by design.
"Flushable" wipes are not. They're made with synthetic fibers that are strong, durable, and resistant to tearing - which is exactly why they do not break apart inside a pump basin.

Instead, they:

Wrap around the impeller

Tangle in the cutter assembly

Jam the pump

Cause high amp draw and overheating

Trip alarm circuits

Burn out motors

The result is a grinder pump that stops working - often in a very expensive way.

Liberty Grinder Pumps Are Tough - But They Have Limits

We trust and install Liberty grinder systems because they are rugged, reliable, and engineered for demanding wastewater duty.

But even the best pump in the world cannot:

They are precision pumps with cutting mechanisms designed for wastewater solids - not everything people think should go down the toilet. They are excellent at what they're built for. Just not miracles.

What Belongs in Your Toilet

If you have a grinder pump, the rule is simple:

Only flush the 3 P's

Pee

Poop

(Toilet) Paper

Everything else belongs in the trash.

Never Flush:

  • Baby wipes
  • "Flushable" wipes
  • Paper towels
  • Feminine products

Also Avoid:

  • Dental floss
  • Grease or fats
  • Cat litter
  • Cleaning pads

Even small amounts over time build into major service calls.

The Real Cost of "Flushable"

A grinder pump service call is not minor. When wipes jam a system, it often involves:

Pump removal from the basin

Cleaning and de-ragging

Replacement of cutter components

Electrical and performance diagnostics

In worst cases, full pump replacement is necessary.
Most wipe-related damage is not covered under warranty, since it's caused by improper materials entering the system. That cost falls on the homeowner.

Protect Your System

Grinder pump systems work extremely well when used properly. We stand behind every Liberty grinder pump we install - wired correctly, sized properly, and set up the right way.

But we cannot control what gets flushed.
The simplest way to avoid an emergency call is discipline in the bathroom.

If it didn't come from your body or off a roll of toilet paper, it goes in the trash.

Final Word

We'll say it again:
Wipes are not flushable.
Grinder pumps are not bulletproof.
And even the best pump on the market still has limits.

If your alarm is going off or your grinder system isn't operating the way it should, give Griffen Pump Service a call.

No gimmicks. No shortcuts. Just real service.
