Installation

Easy installation, immediate protection

The WaStop Inlince Check valve is designed for quick and straightforward installation, providing immediate protection against backflow, flooding and unwanted odours. Thanks to its flexible design, WaStop can be installed in existing pipe systems, chambers or on walls – both horizontally and vertically – without the need for power or control systems.

A standard installation takes approximately 30–60 minutes, depending on size and location. Most municipalities and contractors can carry out the installation themselves without external assistance, saving both time and money.

WaStop comes with clear installation instructions and requires minimal tools. To ensure proper sealing, supplied rubber gaskets or, if needed, swellable sealant are used.

Whether for new installations or retrofitting into existing systems, WaStop offers a reliable, maintenance-free solution for effective flow control.
