How to keep your house safe from rats
The Association of Danish Sewer Contractors have created this video to demonstrate how to stop rats from gaining access to your house. Rats are one of the biggest challenges for the sewer system. Rats gnaw their way into the sewers, build nests and have pups. They are well and safe in the sewers, and they wreak destruction by gnawing. If they gain access to our houses, they will spread bacteria and diseases.
A sure way to keep the rats out is to use rat-safe pipes in stainless steel. With plastic or concrete pipes, there is a risk that the rats gnaw their way through - and it is a costly affair to dig up and re-establish the pipe system from scratch.
Keep the rat out
Avoid inviting rats in to your home by following the three simple guidelines:
- Use stainless steel pipes or other rat-safe pipes in newbuilding or renovation
- Make sure that drain and water trap are made from stainless steel
- Chose a grating in stainless steel that can be screwed to the drain
There will always be rats in the sewer system
As long as there are openings inot the sewers, there will be rats in there. But the choice of material in construction can determine how easy or difficult it should be for rats to gain access to the sewers and possibly access to the building.
How much will it cost to replace the pipes after the house has been built?
This is an important question to consider during the plannning phase of the construction. The costs of the pipe system only make up a very small part of the entire construction. But if you need to replace the pipes at a later stage, the costs will be much greater.
A grating is no obstacle
A rat can easily lift 1 kg and a little more. That is why it is important to select a grating which the rat cannot gnaw its way through and which is screwed to the drain so the rat cannot push it aside.
Use of rat blockers
A rat blocker is a device that is either installed in the pipeline or as part of it. The idea of a rat blocker is that water can pass through, but the rat cannot. This is a job that most rat blockers solve without any problems. But rat blockers may cause other problems, such as reduction of the water supply which affects the sewers' self-cleaning abilities or they may cause congestion.
BLÜCHER's rat stop is a wide expansion of the pipeline and can be used for vertical drainage pipes. The rat stop prevents the rat from moving upwards in the pipe by leaning against the pipe wall.
