Features

• The Forge Anti-Flood sewer valve has been designed to prevent backflow from surcharging sewers.
• Wherever there is danger from rising water backing up into property through the drainage system the valve will close off the backflow automatically to prevent flood damage. In a combined sewer system we recommend that rainwater run off is treated separately until the flooding subsides.
• Forge valves have now been used to protect many basement flats and low lying properties previously affected by foul and combined sewers unable to cope with abnormal weather conditions.
• The Forge Valve is float operated forcing a closure of the pipe when backflow occurs.
• Increased backflow pressure on the flap forces it tighter closed.
• The valves are light and can easily be carried into awkward places.
• No tools are required to remove the lid and gloved hands can easily remove the wing nuts.
• The seal between lid and valve body is designed for life and will not need to be replaced when the valve is opened.
• Float and flap assembly lift out with gloved hand once lid is removed. No tools required.
• Lid bolts remain attached to valve body when wing nuts are removed. The valve is made from polypropylene which is extremely durable and resistant to chemicals. This smooth material resists the build up of fat and can easily be cleaned with a hose.
• The air release valve ensures a quick reaction to rising water levels.
• Available from stock with prompt delivery to suit pipe diameters of 100 mm, 150 mm, 225 mm and 300 mm, other diameters can be manufactured to special order.
• The Forge Anti-Flooding valve is made for connection into public or domestic gravity sewer situations where flooding occurs. It will safeguard low lying property by preventing backflow from a surcharged sewer.
• The valve, which is manufactured from lightweight polypropylene may easily be handled by one man and should be fitted into a separate inspection chamber using flexible pipe couplings.
• The valve is of patented British design and manufacture, it will operate under flood conditions even where the pipe gradient is flat.
