Staufix Basic backwater valve

The solid solution for wastewater.

Staufix Basic backwater valve

Reliable, durable and affordable in price: These properties do not have to be mutually exclusive. This is proven by our Staufix Basic backwater valve. It is the ideal solution to provide protection for individual draining elements such as a shower, washbasin and washing machine which are located below the backwater level.

The Staufix Basic is available as a type 0, 1 and 2. Type 2 has two free-hanging backwater flaps that protect against the ingress of water from the sewer in the event of backwater. In addition, one of these flaps can be manually locked via an emergency closure. The Staufix Basic can be retrofitted.

Installation above ground

The Staufix Basic can be installed in an exposed drainage pipe and is therefore particularly suitable for subsequent installation in basement rooms. The "Clean out drain body" version can be used as a cleaning piece . 

Quick-release closure made from polymer

Smooth in operation – tool-free maintenance

The Staufix Basic is made entirely from polymer – this protects it from corrosion. But this is not the only thing that makes it easy to use: The practical quick-release closure allows the backwater valve to be opened for tool-free maintenance. 

Ideal for renovation work

If a backwater valve no longer fits into the existing pipe, the work and expense can increase. The drop of the Staufix Basic is just 7 mm from the inlet to the drain – so it can be integrated without any problems.
