Installation

Easy installation, immediate protection

The WaStop Inline check valve is designed for quick and straightforward installation, providing immediate protection against backflow, flooding, and unwanted odors. Thanks to its flexible design, WaStop can be installed in existing pipe systems, manholes, or on walls – either horizontally or vertically – with no need for electricity or control systems.

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

WaStop is delivered with clear installation instructions and requires only minimal tools. For proper sealing, included rubber gaskets or, if necessary, swellable sealants are used.

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