Rats gaining access to a property through the drainage system is far more common than most people realise. These pests can squeeze through incredibly small spaces, navigate sewer networks with ease, and enter homes or commercial buildings through damaged, open or unprotected pipework.
But the good news? There is a simple, highly effective solution that stops rats in their tracks: a drainage rat gate.
At Kingfisher Drainage & Jetting, we install high-quality, stainless-steel rat gates designed to protect your property and keep rodents exactly where they belong – out.
How Do Rats Enter Your Property Through Drains?
Rats frequently travel through the main sewer system in search of shelter, warmth and food sources. If your drainage system is unprotected, they can climb upwards through pipework and enter your home via toilets, manholes, kitchen waste pipes or damaged drains.
Once inside, they can cause significant issues, including:
- Chewed pipework and insulation
- Persistent bad smells
- Contamination problems
- Structural damage
- Repeat infestations
Without proper protection, the problem can quickly escalate, leading to expensive repairs and considerable stress.
What Is a Drainage Rat Gate?
A drainage rat gate (also known as a non-return valve) is a robust stainless-steel device fitted inside your drainage line. Its design allows water and waste to flow out of the property, but prevents anything from travelling back in, including rats and other rodents.
The gate seals automatically and requires no maintenance, making it one of the most cost-effective forms of protection you can install.
Benefits of Installing a Rat Gate
✔ Protects Your Home or Business
A rat gate is a simple solution that immediately stops rodents from entering the property through the sewer system.
✔ Prevents Foul Odours
Rodent activity often leads to unpleasant smells in bathrooms, kitchens and outdoor drainage areas. A rat gate eliminates this risk.
✔ Reduces the Risk of Infestation
Rather than tackling rats once they’re inside, a rat gate prevents them from ever gaining access—saving you time, money and frustration.
✔ Long-Lasting Peace of Mind
Made from durable stainless steel, our rat gates are built to last, offering year-round protection.
