The FloPlast 110mm Round Top Back Inlet Gully (UGG7BM) combines a compact access cover with a rear (back) inlet, making it ideal where the lateral pipe approaches from the side. The internal bottle trap retains a water seal to stop odours, and the 110mm spigot outlet pushes straight into underground pipework. Manufactured from durable PVC-U to BS EN 1401-1 for reliable performance in domestic and light-commercial drainage.
