WaStop Access Chamber prevents backflow. WaStop Access Chamber is delivered with WaStop check valves already installed, and 2,15 m spindle extension. The chamber is constructed to fit shaft dimension 460mm.
Install the WaStop Access simply by placing it inline and attaching with flexible couplings or muffs. A 2% fall in the pipeline is recommended. WaStop Access Chamber is delivered ready for use.
Maintenance
The only maintenance required is that the WaStop module should be removed for inspection, and rinsed if needed, once a year. After a suspected backflow event it is recommended that the chamber is inspected and rinsed if required. The O-ring in the PVC plate should be greased with silicone or similar every time the WaStop module is removed.

Models 100-200mm are tested and approved for up to 5m backpressure. Other dimensions are tested up to 3m meters backpressure. WaStop is patented in the EU, USA and other countries.
We at Wapro know that any solution for flood prevention, or odour control needs to function. Simply, effectively. That’s why, when we invented the WaStop inline check valve in 2000 we had one thought in mind. Instant automatic protection. Working on differential pressure the WaStop functions autonomously, without human interaction, without electricity, without constant maintenance. It just works. To invent the best inline check valve on the market our engineers went one step further.
WaStop’s ingenious function combines common sense and simplicity, to provide our customers with the best possible protection against flooding, odor control and backflow. In order to protect against flooding, we at Wapro have engineered the WaStop to ensure the lowest possible opening pressure whilst maintaining the best possible seal against backflow. This, combined with the lowest headloss available, gives the most efficient flow conditions, ensuring the fastest evacuation of water. An essential quality of check valves used to protect people and property.
