GROUNDWATER CHAMBER 400/315 INCL. NO-RETURN VALVE

Ready-made pit stop package for property surface water. The product is used to collect property subsurface and rainwater before directing it, for example, to a municipal stormwater sewer. The body diameter is 400 mm and the telescope diameter is 315 mm. The telescope is equipped with a floating cast iron solid lid with a load capacity of 40 tons. The sand trap height is 75 cm = 70 liters. The pit body is equipped with welded inlet and outlet connections with a diameter of 110 mm. The inlet connection (for subsurface water) is fitted with a ball check valve that prevents backflow into the subsurface line during potential flooding. The outlet connection is equipped with a water seal and a flushing pipe. The inlet connection is positioned 24 cm higher than the outlet connection. Additional connections to the pit body can be made, for example, using a coring tool, and if necessary, using aftermarket fittings or aftermarket inlet adapters. The 400/315 telescope ring on the top of the body is secured with screws and can be removed if necessary, for example, if the body needs to be shortened.
