Water meter boxes 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 boxes are included in Valrom Industrie’s Company Technical Standard STF 9/2005. Double-wall construction version: monolithic structure with an outer layer of compact material (mass-colored polyethylene) and an inner expanded polyethylene layer with blowing agents. Components: – water meter box body – lid insulation gasket – thermally insulated lid – installation for up to 2 (depending on the box diameter), generally consisting of polyethylene pipes, compression fittings, and shut-off valves. Installations with customized components can be made as needed. Benefits: The monobloc construction, double-wall, 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 box mechanical rigidity without increasing its weight and, implicitly, handling and transport time or costs. Technical approval and technical assessment for use in construction.
