What is a back inlet gully used for?

A back inlet gully is used where the drainage pipe enters from the back or side rather than above, allowing for compact or restricted routing of underground pipework.

Is the UGG7BM gully compatible with standard 110 mm systems?

Yes. UGG7BM uses a 110 mm spigot outlet and conforms to BS EN 1401-1, making it compatible with typical underground drainage systems from FloPlast and other UK manufacturers.

How is the gully maintained?

The round top cover can be removed to allow access to the internal bottle trap for inspection and cleaning. Occasionally debris or silt may need flushing out to maintain performance.

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.
