Product Overview
110mm Low Back P Trap Gully manufactured from durable uPVC to BS EN 1401-1, designed for underground use to collect surface water and discharge it into underground drainage while preventing foul odours from escaping.
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 90° low back outlet, it is designed for installations where the outlet pipe must run directly out at a right angle, making it particularly effective for positioning against walls or in confined spaces with limited room for pipework adjustment.
