Water meter pits are compact, monoblock products (without joints or welds), made of polyethylene (PE), manufactured using rotomolding technology. They are designed to protect the water meter and the connection installation. Manufacturing conditions and general quality requirements for water meter pits are included in Valrom Industrie’s Company Technical Standard STF 9/2005. Compact wall construction variant: single-layer wall made of compact material (mass-colored polyethylene). Component elements: water meter pit body, insulation gasket for the lid, thermally insulated lid, 15 mm thick expanded polyethylene (PEE) thermal insulation foil, and an installation of up to 2 (depending on the pit diameter) generally consisting of polyethylene pipes, compression fittings, and isolation valves. Customized installations can be created according to specific needs. Benefits: The monoblock construction, the thermally insulated lid, and the design solutions for the closure and sealing of the rubber gasket at the lid and for wall penetrations prevent water infiltration and protect the internal installation from freezing. The reinforced geometry, with horizontal and vertical ribs, provides mechanical rigidity to the pit without increasing its weight and, implicitly, the handling and transport time or costs. Approved and technically certified for use in construction.
