Operating principle

The rat stopper works with a targeted diameter expansion inside the soil pipe.

This prevents rats from using the pipe walls to support themselves and climb upwards.

The system works purely mechanically and requires:

• no flaps
• no electronics
• no chemicals

This ensures continuous safe and trouble-free operation.

Suitable for the following applications

• Residential houses
• Multi-family houses
• Property management companies
• Commercial properties
• Industrial facilities
• Public buildings
• Renovation projects
• New constructions

Suitable for the following pipe sizes

Standard versions:

• DN 100–200

Asymmetric versions:

• DN 75–200

Suitable for:

• wastewater containing feces

Asymmetric rat stopper

Optimal for pipes running directly along the wall.

Advantages:

• less chiseling work
• easy retrofitting
• ideal for renovations in existing buildings

High-quality stainless steel

The rat stopper is made of stainless V2A steel.

As a result, the system is:

• corrosion-resistant
• dimensionally stable
• durable
• resistant to moisture and wastewater

Compared to simple plastic solutions, stainless steel offers significantly higher operational safety and durability.

Installation and assembly

Installation takes place in a vertical soil pipe.

In the process:

1. a pipe section is removed,
