What is Ratwall?

Ingenious Rat Barrier Drain Protection

Ratwall is a simple but highly effective rat drain barrier protection system for homes and businesses. Ratwall is a precision engineered, stainless steel ‘rat flap’ device for installation within a drainage or pipe system.

How does Ratwall work?

The Rat Flap for Drains

Ratwall provides a low cost, effective solution for 100 & 150mm drainage systems in clay, PVC and cast iron materials.

Most homes have one main drainage outlet point before connecting to the main sewer, the Ratwall rat drain blocker is installed at this point effectively rat proofing and protecting the whole upstream drainage system from Rat invasion.

Ratwall is capable of a hinge-less opening to the full diameter of the pipe, allowing maximum flow rates at all times. The engineered shape of the rat flap device ensures it cannot become dislodged and lost in drainage line. Rats cannot pass the device against the flow.
