Why Rodent and Insect Overflow Screens Are Essential — And Why MP Products Is Leading the Way
When it comes to protecting buildings from pests, most people think about doors, windows, and visible entry points. But in reality, some of the biggest risks are hidden underground, in drainage systems, overflow pipes, and water storage outlets.
These overlooked areas can act as open gateways for rodents and insects, allowing them to enter properties unnoticed. That’s why overflow screens are no longer just an optional upgrade, they’re a critical part of modern plumbing protection.
And when it comes to reliable, purpose-built solutions in the UK, MP Products Overflow Screens Range stands out as a specialist provider delivering high-quality, engineered protection for real-world applications.
The Problem Most Properties Don’t See Coming
Overflow pipes are designed to safely discharge excess water from tanks, drainage systems, and rainwater setups. But while they serve an essential purpose, they also create a direct opening into your system.
Without protection, these openings allow:
Rats and mice to travel through pipework
Insects to nest in damp environments
Debris to enter and cause blockages
Rodents, in particular, can squeeze through surprisingly small gaps, while insects are naturally drawn to moisture and stagnant water. Left unprotected, overflow systems can quickly become a hidden entry route into homes, commercial buildings, and even critical environments like hospitals or food facilities.
The Role of Overflow Screens (And Why They Work)
Overflow screens act as a simple but highly effective barrier. Installed directly onto overflow outlets, they allow water to flow freely while preventing pests and debris from entering.
What makes modern systems, like those from MP Products, especially effective is the combination of:
Fine stainless-steel mesh
Durable, weather-resistant construction
Smart fittings for secure installation
For example, many of their systems incorporate 57-micron stainless steel mesh, which is fine enough to block insects and rodents while maintaining unrestricted water flow.
This balance between protection and performance is what makes overflow screens such a powerful long-term solution.
Why MP Products Overflow Screens Stand Out
Not all overflow screens are created equal. What separates MP Products is their focus on engineered solutions rather than generic fittings.
1. Designed for Real-World Conditions
MP Products screens are built using robust materials like ABS and PVC bodies combined with corrosion-resistant stainless steel mesh.
This means they can withstand:
Constant moisture exposure
Outdoor weather conditions
Chemical and environmental stress
Whether installed on a domestic water tank or a large industrial drainage system, they’re designed to last.
2. Wide Range of Connection Types
One of the biggest challenges in drainage systems is compatibility. MP Products solves this by offering multiple fitting options, including:
Universal connector screens – adaptable to various pipe sizes without extra fittings
BSP threaded screens – ideal for standard plumbing systems
Flanged screens – heavy-duty solutions for larger or high-pressure applications
Compression fittings – perfect for retrofit projects
This flexibility means their products can be used across residential, commercial, industrial, and agricultural systems without complicated modifications.
3. True Preventative Pest Control
Unlike reactive pest control methods, overflow screens stop problems before they begin.
MP Products systems are specifically designed to:
Block rodents, insects, and debris at the entry point
Reduce contamination risks in water systems
Prevent infestations in sensitive environments
Their screens are widely used in settings where hygiene is critical, such as commercial kitchens, healthcare facilities, and food storage areas.
This makes them not just a convenience, but a necessity.
4. Easy Installation and Low Maintenance
Another key advantage is simplicity.
Many MP Products screens are designed with:
Universal Flexseal connectors for quick installation
Optional unions for easy removal and cleaning
Secure fittings that don’t require specialist tools
Once installed, they require minimal maintenance while continuing to protect systems long-term.
Applications: Where These Screens Make the Biggest Difference
One of the strengths of MP Products is how versatile their solutions are. Their overflow screens are used across a wide range of environments:
Residential Properties
Loft water tanks
Rainwater harvesting systems
External overflow pipes
Even small domestic systems can benefit, preventing pests from entering and maintaining a clean, safe environment.
Commercial Buildings
Offices and retail spaces
Restaurants and food preparation areas
Warehouses and storage facilities
In these settings, pest control is directly tied to reputation, compliance, and operational continuity.
Industrial and Agricultural Systems
Large-scale drainage networks
Irrigation and storage tanks
Outdoor and exposed pipework
Heavy-duty options like flanged screens provide the durability needed for demanding environments.
Hygiene, Compliance, and Peace of Mind
In many industries, pest prevention isn’t just best practice, it’s a requirement.
Overflow screens help:
Maintain hygiene standards
Reduce contamination risks
Support compliance with health and safety regulations
MP Products specifically highlights their use in environments where cleanliness is critical, reinforcing their role in protecting both infrastructure and public health.
A Small Upgrade with Long-Term Impact
What makes overflow screens particularly compelling is how small the investment is compared to the risks they prevent.
Without protection, you could be dealing with:
Pest infestations
Blocked or damaged pipework
Expensive repairs and downtime
Health and safety issues
With a properly installed screen, those risks are dramatically reduced.
As MP Products themselves emphasise, overflow screens are a simple but highly effective way to prevent problems before they start.
