When people think of blocked drains, they usually imagine grease, fat, and waste causing the problem. However, rodents are one of the most overlooked causes of drainage issues. At Portsmouth Drains24, we’ve seen firsthand how rats nesting in drains can lead to serious blockages — and how simple preventative measures, like installing a rat stopper for drains, can solve the problem before it starts.
How Do Rats Cause Blocked Drains?
Rats are drawn to drains because they offer warmth, moisture, and access to food waste. Once inside, they gnaw through pipework, build nests from debris, and cause structural damage that leads to:
✅ Collapsed pipework
✅ Blockages from nesting materials
✅ Wastewater backups
✅ Long-term damage requiring expensive repairs
If you’re experiencing blocked drains in Portsmouth, rodents could be part of the problem — even if you haven’t seen them yet.
The Solution: Install a Rat Stopper for Drains
Prevention is far cheaper than cure. Rat stoppers for drains work by blocking rodents from gaining access in the first place. This small investment can protect you from large repair bills and ongoing drain blockages.
