Permanently stopping rats in downpipes
Rats often enter buildings unnoticed via the sewage system. Especially older downpipes and drainage systems provide ideal routes into basements, utility rooms, storage rooms, or other building areas.
The stainless steel rat stop from ERO Edelstahl reliably prevents rats from climbing up vertical downpipes – permanently, maintenance-free, and completely without poison or chemicals.
The solution is suitable for residential buildings, commercial properties, industrial facilities, and public institutions.
Why rats enter buildings via the sewage system
Many buildings have older pipe systems with deposits or rough internal surfaces. These allow rats to move upwards piece by piece even in vertical pipes.
Typical entry points:
- Wastewater pipes
- Rainwater downpipes
- Older house connections
- Unsecured downpipes
- Pipe systems in need of renovation
Particularly problematic:
An infestation is often only detected when damage, odor problems, or hygiene risks have already occurred.
The permanent solution without poison or chemicals
Unlike traditional pest control measures, the rat stop works purely mechanically.
It uses:
- No poisons
- No bait systems
- No chemicals
- No movable flaps
required.
This makes the system ideal for:
- Residential buildings
- Property management
- Gastronomy
- Food areas
- Commercial properties
- Public facilities
How the stainless steel rat stop works
The so-called rat funnel utilizes a simple but highly effective principle:
By purposefully increasing the diameter within the downpipe, the animals lose the necessary grip on the pipe wall. This prevents them from climbing up.
Since the system works without mechanical flaps, there is no risk of:
- Blockages
- Jammed components
- Obstructions
- Increased maintenance effort
The system remains permanently functional and self-cleaning.
Maintenance-free and self-cleaning
The stainless steel rat stop was developed for long-term and trouble-free operation.
Advantages:
- 100% maintenance-free
- Self-cleaning
- No moving parts
- High operational reliability
- No ongoing maintenance costs
Especially for larger buildings or commercial properties, this permanently reduces follow-up costs and maintenance effort.
High-quality stainless steel – Made in Germany
The rat stop is made of V2A stainless steel and convinces with a particularly durable construction.
Advantages of stainless steel:
- Corrosion-resistant
- Dimensionally stable
- Durable
- Resistant to moisture and wastewater
- Significantly more robust than simple plastic solutions
Production takes place in Germany.
Suitable for numerous applications
The stainless steel rat stop is suitable for, among others:
- Residential houses
- Multi-family houses
- Property management
- Commercial properties
- Industrial facilities
- Gastronomy
- Public buildings
- New constructions
- Renovations of existing buildings
Easy retrofitting of existing downpipes
Installation takes place directly in the vertical downpipe – often in the basement area.
A section of the pipe is removed, and the rat stop is inserted. Installation is possible in both existing buildings and new constructions.
Depending on the installation situation, symmetrical and asymmetrical variants are available.
Which pipe sizes is the rat stop suitable for?
Suitable for:
- DN 100–200
- Asymmetrical variants: DN 75–200
Can be used for:
- Faecal wastewater
- Rainwater pipes
Protect buildings permanently now
Early protection of downpipes prevents later damage, hygiene problems, and costly pest control measures.
