ABSTRACT:
A surface box for a stop cock (25-29) and water meter (40) has a housing (1) of moulded plastics with ports (10, 11) in the base for the external connection of pipes. Another moulded plastics body (20) is screwed down to the base, inside the housing, and forms part of a passage from port to port. A stop cock (25-29) is carried by this body and can be operated through the top of the housing to close over the mouth of a duct formed within the base from the inlet port. Downstream of the stop cock, a screw cap (39) forming a wall of the passage can be removed and replaced by a water meter (40) which co-operates with the body in such a way that water has to flow through it. Further downstream, a non-return valve (37) or a further stop cock is carried by the body. There are no pipe connections made inside the housing, and the stop cock(s) and screw elements are operable within narrow confines, allowing a very compact box.
