Product Overview
110mm Underground Drainage Universal P Trap Gully manufactured from durable uPVC to BS EN 1401-1, designed to prevent foul odours from escaping the drainage system while providing a secure connection for surface water.
The gully incorporates an integral P trap water seal, which maintains a standing water barrier inside the fitting. This prevents gases from the underground drainage system from venting back into the property or outdoor spaces.
Supplied with a 45° outlet, it allows the discharge pipe to leave the gully at an angled direction, making it particularly suitable for installations where the pipe run needs to divert away from the gully position while maintaining smooth flow.
