Water Filtration & Treatment
Water filtration vendors install and service the cartridges, softeners, RO systems, and chemical conditioning that filters NYC tap water before it hits the espresso machine, the soda gun, the ice machine, the combi oven, the dish machine, and the guest sink. You install at buildout and replace cartridges on a service schedule. NYC LL 159 takes effect May 7, 2026, tightening cooling-tower Legionella testing from quarterly to monthly, so hotels with cooling towers need biocide, softening, and filtration integrated into the maintenance program plan.
