This WaterMark Technical Specification sets out requirements for plastics bodied fittings of nominal sizes up to DN 225 with intermediate flexible joints for sewer or drain applications. These fittings are for use above ground or below ground and intended to be used where the pipeline is operating under gravity flow and the operating pressure is low. The design of the fitting is such that it compensates for misalignment or movement that may be encountered in pipeline installations.
