What Not to Flush: Protecting Your Drains and the Environment
You might think your toilet can handle anything you flush down it, but that’s a common misconception. Every year, improper flushing leads to thousands of drain blockages and contributes to environmental issues like fatbergs and water pollution. At Metro Rod, we’re on a mission to help you understand what not to flush and why it matters.
Common Items You Should Never Flush:
- Wet Wipes Even those labelled “flushable” don’t break down like toilet paper. They clump together and cause stubborn blockages.
- Nappies and Sanitary Products Highly absorbent and bulky, these items can cause instant clogs.
- Cotton Buds and Dental Floss These items tangle together in pipes, trapping other waste and forming larger blockages.
- Fat, Oil & Grease (FOG) When poured down the sink, these cool and solidify, forming the infamous fatbergs that block entire sewer systems.
Why It Matters
Improper disposal leads to:
- Costly plumbing repairs
- Environmental damage
- Sewer overflows and flooding
Sustainable Drainage Habits
- Use a bin for wipes, nappies, and sanitary products.
- Pour cooled fat, oil, and grease into a container and dispose of it in the bin.
- Install strainers in sinks and showers to catch food and hair.
- Educate your household or staff about the 3 Ps rule: Only flush pee, poo, and paper.
