To comply with water regulations for multi dwelling occupancies, use Plasson multi port manifolds with meter mount kits A or B. Kits contain stop tap, meter housing, double check valve (WRAS approved), drain valve (WRAS approved) and connection to either 25mm PE or 22mm copper/PB/PEX. Blanking off an end feed manifold requires a dead leg kit to remove the possibility of stagnant water.
