What is the purpose of a bottle gully like the FloPlast UGG4?

The FloPlast UGG4 acts as a trap and access point in underground drainage systems — it prevents foul odours escaping whilst allowing inspection and maintenance via its rectangular top.

Is the rectangular top bottle gully compatible with 110 mm systems?

Yes. The UGG4 connects via a 110 mm spigot and complies with BS EN 1401-1, making it compatible with most UK 110 mm drainage systems including FloPlast, Marley, Brett Martin, and others.

Where is the UGG4 installed?

The UGG4 is typically used at points where waste or rainwater outlets join underground drainage, especially where maintenance access is required and space is constrained.
