6 Things That Should Never Be Flushed

The toilet and the trash can are not the same thing. Your toilet is designed to handle two things: human waste and toilet paper.

But every day, household items that seem harmless get flushed anyway — and many of them can contribute to clogs, sewer backups, damaged pipes, and unnecessary repair costs.

Trash can do a lot of damage to your home’s pipes, especially an aging sewer line, and even the municipal sewer system. And doing so also wastes water — depending on the brand and model of your home toilets, you can waste about three gallons of water each time you flush.

In this post, Bob Oates Sewer & Rooter will discuss six things that should never be flushed — and what to do instead.

1. Food

Food may seem harmless once it disappears down the drain. As experts in sewer repair, we can tell you that’s not the case. Many items absorb water, expand, or stick inside pipes. Pasta, rice, grease, and cooking fats are especially common contributors to buildup and restricted flow. Grease/fats/oils go down smoothly but each soon solidifies, lining the inside of pipes and creating major jams.

Better option: Dispose of food scraps and grease in the trash or appropriate waste containers.

2. Condoms

Condoms are designed to remain durable — not dissolve in water. Because they don’t break down like toilet paper, they can catch inside plumbing and contribute to blockages over time.

Better option: Wrap and dispose in household trash.

3. Pets

Small pets and fish are sometimes given water burials, but toilets and sewer systems are not designed for this purpose. Bones and organic material may not break down as expected and can create unnecessary plumbing issues.

Better option: Follow local guidance for pet burial or disposal.

4. Diapers

Diapers are built to absorb and expand — exactly the opposite of what plumbing systems need! Even a single diaper can create a stubborn blockage.

Better option: Take it from your trusted Seattle plumber — dispose of diapers in the trash.

5. Paint and Construction Debris

Paint, drywall dust, grout, and construction materials can coat pipes, harden, and restrict drainage. These materials are especially problematic once they begin collecting other debris.

Better option: Refer to local disposal guidelines for renovation materials.

6. Medications and Drug Paraphernalia

Prescription medications should not be flushed unless disposal instructions specifically direct otherwise. Many communities offer disposal programs designed to keep medications out of wastewater systems.

Items like syringes, gloves, and packaging should also never enter household plumbing.

Better option: Use approved medication and medical paraphernalia disposal programs.

A job well done! One of our techs giving the thumbs up after finishing a bathroom repair.

Wrapping Up

A good rule of thumb:

If it isn’t toilet paper or human waste, it probably doesn’t belong in the toilet.

Also:

Preventing clogs is usually easier than clearing them later.

And if something from this list does get flushed accidentally, avoid repeated flushing — especially if water starts rising, draining slowly, or behaving unexpectedly.
