Single lockable check valve for waste water. The valve prevents backflow from the sewer and the lock function is ideal to “seal off” the sewer for maintenance. The flap is made of stainless steel ensuring rodents cant chew through to get access to the premises. the removable flap assembly allows for maintenance and rodding if needed. The sturdy design will ensure hassle free use for years. This product should form part of any installation. Great value and functionality.
