What is the purpose of the 450 mm chamber base?

The chamber base serves as the foundation of an inspection chamber, facilitating the connection of multiple 110 mm drainage paths (three inlets and one outlet) for access and maintenance.

Which risers and covers are compatible with this base?

It works with the 450 mm riser (UGRL) and can be paired with 450 mm chamber covers (such as MCCRPL and MCCRCI) for a complete chamber system.

Is this base suitable for underground installation?

Yes — built from durable PVC-U, the base is certified to BS EN 13598-1 and intended for use in underground drainage systems.

How many pipe connections does the FloPlast 450mm chamber base accommodate?

The chamber base features four connections total - three main inlets and one outlet, all designed for 110mm drainage pipes with push-fit seals.

What depth can I install this chamber base at?

The base itself doesn't determine installation depth - this depends on the number of 450mm risers (UGRL) you stack on top to reach your required surface level.

Does this chamber base comply with UK drainage standards?

Yes, it complies with BS EN 13598-1, which is the British Standard for plastic piping systems for non-pressure underground drainage and sewerage.

Can I connect different angle pipes to the inlets?

The three inlets accept standard 110mm drainage pipes, and you can use appropriate drainage fittings like bends or junctions before connecting to achieve your required pipe angles.

What covers are compatible with this 450mm chamber base?

It's compatible with FloPlast 450mm covers including the MCCRPL (plastic) and MCCRCI (cast iron) options, depending on your load requirements.

Is the push-fit seal system reliable for underground installation?

Yes, the push-fit seals provide watertight connections and are specifically designed for underground drainage applications where reliable sealing is critical.

Can I cut additional inlet holes in this chamber base?

While the PVC-U material can be cut, it's not recommended as it would compromise the structural integrity and watertight performance of the manufactured unit.

What's the maximum traffic loading this chamber base can handle?

The traffic load capacity depends on the cover you choose and installation depth - check the specifications of your selected cover (MCCRPL for light duty, MCCRCI for heavier loading).
