Frequently Asked Questions

The unvented essentials: Kit A’s expansion vessel and non return valve absorb heated expansion, Kit B’s 3.5 bar valve tames inlet pressure and Kit C’s tundish makes the discharge visible, fitted per the heater’s instructions.

On schedule, not on failure: submicron filters swap per the maintenance interval, keeping taste and protecting the heater, stated per model.

The sink-free install: the font mounts the tap with integrated drainage where no sink exists, in bright chrome, brushed chrome and matt black.

By litres and generation: 1.5-3 litre, 5-7 litre G2 and 10-40 litre G3 and G4 kits carry the seals and parts their class needs.

The sparkling option: twin 1.25kg replacement cylinders keep sparkling HydroTap models carbonating.

No: fonts, filters and kits pair with their systems, which every listing states.
