The Shocking Toilet Discovery from Holmes On Homes

In the podcast episode, Mike Holmes shared an eye-opening story about a plumbing issue that turned out to be more than just a simple clog. The culprit? A diaper flushed down the toilet, causing significant plumbing challenges.

The Discovery: During a routine plumbing inspection, Mike and his team were called to a home experiencing persistent toilet blockages. Upon investigation, they discovered a diaper lodged in the pipes, a surprising and unusual find.

Can I Flush Flushable Wipes Down The Toilet?

Many products labeled as “flushable,” such as wipes and hygiene products, can cause significant blockages in plumbing systems. These items do not break down like toilet paper and can lead to costly repairs.

Can I Flush Diapers Down The Toilet?

No. Diapers, like many other non-flushable items, can expand and create severe blockages, leading to costly repairs and potential water damage.

Can I Flush Tampons Down The Toilet?

Tampons are not flushable! Protect your plumbing and the environment by disposing of them in the trash. Let’s keep our pipes clear. Feminine hygiene products are not to be flushed down the toilet.

Can I Pour Grease Down The Sink?

While it might seem convenient, pouring grease or oils down the toilet can solidify and cause blockages. Instead, dispose of these substances in a sealed container in the trash. Household Waste: Items like diapers, cotton balls, and dental floss should never be flushed. These materials can expand and create clogs that are difficult to remove.

Flushing inappropriate items not only affects your plumbing but also has broader environmental consequences. Blockages can lead to sewage overflows, impacting local waterways and wildlife.

By being mindful of what goes down the toilet, homeowners can avoid plumbing disasters and contribute to a healthier environment. For more tips and expert advice, listen to the full Holmes on Homes episode on Spotify, Apple Podcasts, YouTube, and Amazon Music.

Why Home Maintenance Matters More Than Homeowners Realize

A home is a system. When one part fails, it affects everything else.

Here’s what I see all the time:

Moisture problems that start with an ignored gutter
Structural issues caused by a tiny roof leak
HVAC systems dying early because filters never got changed
Electrical hazards created by outdated or overloaded panels
Drafts, mold, or heat loss from neglected caulking and insulation

None of these happen suddenly. They’re slow-burn issues that creep up because homeowners don’t notice—or choose not to look.

Maintenance is your first line of defense.
