Billi B-4000 - FAQS

Absolutely. In fact your dispenser can be installed up to 2.0m from its undersink water filter. Remember, there will be a boiling water delay with a long extension.

We recommend a new filter at least every 6-12 months, depending on usage and water quality.

Yes. You should always use the correct filter for your water system.

Yes. As filters catch contaminants, they become soiled. Billi under sink water systems use mains pressure, so reduced chilled water flow indicates you should change filters.

The indicator lights tell you what’s going on. Flashing red means boiling water hasn’t reached 99C yet. Flashing blue means water hasn’t chilled to set temperature. Both lights will glow solid when this happens.

The heating element may have blown or overloaded.  Call an authorised Billi agent to repair your undersink water system.

Contaminants collected in your undersink filter become concentrated when filters reach the end of their life and can affect water taste. Ensure that the filter is replaced at least every 12 months or 6,000 litres.

Yes.  Billi Font is available for this purpose in a finish to match your filtered water dispenser.

If the Billi dispenser lights are illuminated, your B-4000 water system is on.
