Riserva Filter Head — Duplex
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Water — the ingredient nobody tastes and everyone drinks
The Riserva is the sensible guardian: a brass head with metered bypass, cartridges matched to espresso duty, and changes that are a hand-turn instead of a plumber. Scale never gets a vote.
Scale is the silent tax on every espresso bar. We remove it before it exists: rated membranes, bypass blending you can actually set, TDS readouts you can actually trust, and remineralisation that puts back exactly the ions extraction wants. Fittings are John Guest-compatible push-fit; leak trays and shutoffs come standard.

Questions, Answered
Which system for my machine?
Send your water report and machine model to the concierge; sizing the treatment to the actual mains water is the whole trade, and it is free.
Does RO waste much water?
Modern membranes with pressure assistance run far tighter than the old horror stories; drain ratios are in the specification, and drain-water heat is negligible at espresso volumes.
