Why Are Rodents in My Drains?
Finding rats in your drains is stressful. They’re drawn by food smells, waste lines, and any structural weakness in your drainage network. Even small cracks in your drain, displaced joints or gaps can allow rodents to enter the system. Their climbing ability enables them to navigate through sewer tunnels and up into domestic drains.
If you want lasting peace of mind that rats cannot enter your property, BN Drainage will install rat gates inside the drains to seal off rodent access.
Gates for sewer rats
During a CCTV drain survey, we can detect rodent activity and identify access routes within your drains. Once we confirm where rats are travelling, our team fits rat gates appropriately in the drain runs or junctions, thereby preventing any new rodents from entering the system.
Rat Gates for Drain Protection
If rodents have already been cleared from your drains you will still need protection. Our rat gates (designed for drains, not drainpipes) allow wastewater to flow out while blocking rats from coming back in. They’re a simple, passive barrier that works quietly and effectively — safeguarding your property from future infestations.

FAQs About Rodent Prevention & Rat Gate Installation
How can I tell if my drains are at risk of a rodent problem?
If your property is near open land, food establishments, or older drainage systems, there’s a higher chance that rats may use the sewers to reach your home. Regular drain maintenance and a professional inspection can reveal early signs of damage or entry routes before rodents get in.
Do I need both pest control and drainage specialists to deal with rats?
Not necessarily. BN Drainage offers both rodent control and drain expertise, meaning you won’t need two separate companies. We can remove existing rodents and address the root cause in the drains, ensuring the issue doesn’t come back.
Will installing a rat gate affect my drainage performance?
No, rat gates are designed to allow full wastewater flow while blocking rodents. They don’t restrict or slow down drainage when correctly fitted by professionals. You’ll notice no change in your plumbing performance after installation.
How long do rat gates last once installed?
When properly maintained, rat gates can last for many years. They’re made from durable stainless steel that resists rust, corrosion, and damage from rodents or debris. We recommend having your drains checked every couple of years to make sure the gate remains clear and secure.
Can rats chew through a rat gate?
No. Rat gates are made of stainless steel — far tougher than plastic or rubber fittings. Rats cannot gnaw through them, making them one of the most reliable long-term rodent prevention measures available.
Can I maintain or clean a rat gate myself?
It’s best left to professionals. While rat gates require very little maintenance, an annual drain inspection ensures they remain free of blockages and securely fitted. Attempting to access drains without proper tools can be unsafe and may damage the gate.
Will installing rat gates help prevent other problems, too?
Yes. By sealing vulnerable points in your drainage system, rat gates can also reduce the risk of foul odours, water backflow, and other pests using the same routes. They contribute to better overall drainage hygiene and property protection.
How quickly can BN Drainage respond to a rodent prevention enquiry?
We offer a prompt response across London and the surrounding areas. In most cases, we can arrange a site visit or CCTV survey within 24–48 hours to assess the issue and recommend the right solution.
