Water meter pits are compact, monobloc products (without joints or welds), made of polyethylene (PE), manufactured using the technology known as rotomoulding. They are intended to protect the water meter and the service connection installation. The manufacturing conditions and general quality requirements for water meter pits are included in Valrom Industrie’s Company Technical Standard STF 9/2005. Construction version with solid wall: single-layer wall made of solid material (polyethylene coloured in the mass). Component elements: – water meter pit body – lid insulation gasket – thermally insulated lid – thermal insulation film made of expanded polyethylene (EPE) with a thickness of 15 mm – 3/4″ installation consisting of: polyethylene pipes, compression fittings and shut-off valves. Installations with customised components can be made depending on requirements – DN20 water meter. Benefits: The monobloc construction, the thermally insulated lid and the design solutions for closure and sealing of penetrations (rubber gasket at the lid and for wall penetrations) make water infiltration impossible and protect the internal installation from freezing. The reinforced geometry, with horizontal and vertical ribs, gives the pit mechanical rigidity without increasing its weight and, implicitly, handling and transport time or costs. Approval and technical certification for use in construction.
