What is the FloPlast 110mm Rectangular Hopper used for?

It funnels surface water into 110mm underground drainage systems via its rectangular inlet.

Is it compatible with other 110mm systems?

Yes. It conforms to BS EN 1401-1, making it compatible with FloPlast, Marley, Brett Martin, and other UK 110mm systems.

What's the maximum flow rate this hopper can handle?

The FloPlast 110mm Underground Rectangular Hopper is designed to handle typical domestic rainwater flows from standard downpipes. For commercial applications or areas with exceptionally heavy rainfall, consider the drainage system capacity as a whole.

How deep should I install this hopper below ground level?

Install the hopper so the rectangular grid sits flush with or slightly below the finished ground surface. Ensure adequate fall towards the 110mm outlet pipe for proper drainage.

Can I connect this directly to existing clay drainage pipes?

Yes, you can connect to clay pipes using appropriate adaptors or couplers designed for 110mm PVC-U to clay connections. Ensure proper sealing to prevent root ingress or leakage.

What's the loading capacity of the rectangular grid?

The grid is designed for light pedestrian traffic typical in domestic settings. For areas with vehicle access or heavy loading, consider installing additional protection or a heavy-duty alternative.

Does this hopper require any special bedding or backfill?

Use appropriate granular bedding around the hopper body and compact backfill material in layers. Avoid using sharp stones or hardcore that could damage the PVC-U body.

Can I retrofit this hopper into an existing underground system?

Yes, provided you can excavate access to the existing 110mm pipework. You'll need to cut into the existing pipe run and install appropriate fittings to accommodate the hopper outlet.

What maintenance does this underground hopper require?

Regularly clear debris from the rectangular grid and check for blockages. The grid can be lifted for cleaning access to the hopper chamber if sediment builds up over time.

Is the hopper suitable for chemical or industrial drainage applications?

This hopper is designed for rainwater and surface water drainage only. It's not suitable for chemical waste, industrial effluent, or foul drainage applications.
