P Trap Gully – PVC – Underground Drainage

Product Overview

The 110mm Underground Drainage Universal P Trap Gully is crafted from durable uPVC, adhering to BS EN 1401-1 standards. It is designed to effectively prevent foul odors from escaping the drainage system while ensuring a secure connection for surface water.

The gully features an integral P trap water seal, maintaining a standing water barrier inside the fitting. This prevents gases from the underground drainage system from venting back into your property or outdoor spaces.

With a 45° outlet, the gully allows the discharge pipe to leave at an angled direction, making it especially suitable for installations requiring pipe runs to divert away from the gully position while maintaining smooth flow.
