Brass waste couplings are widely popular as the important couplings for both homes and businesses. These top-quality, rustproof and durable fittings have been made to attach the waste pipe from basin, sink and other fittings to the drainage system. These make a crucial role in the appropriate functioning of the wide-ranging plumbing system. If properly installed they never make the returning of wastes and contaminants into fixtures. These have been made to prevent leakage and blockages in waste pipe.
