Commercial water filtration systems
Higher-capacity filtration and softening for cafés, restaurants, offices, salons, gyms and other premises, where flow rates, compliance and documented maintenance all matter.
Commercial water treatment differs from domestic in three ways that all matter more than the hardware does. Flow rates are higher, so equipment sized for a house will not cope. Downtime is expensive, so bypasses and duty-standby arrangements become worth their cost. And there is usually somebody who will want to see records.
The commonest commercial driver in the UK is not drinking water at all — it is protecting equipment. An espresso machine, combi oven, dishwasher or steamer in a hard water area will fail early and expensively without treatment, and most manufacturers make some form of water treatment a warranty condition.
Food businesses have the additional consideration that water is an ingredient, and food safety management systems generally expect filtration and its maintenance to be documented. Keeping the service records is part of the installation, not an afterthought.

Skill level: Professional
Commercial installation involves sizing against measured demand, backflow protection appropriate to the fluid category on the premises, and in food businesses an installation that will satisfy an environmental health inspection. It is specialist work and is priced accordingly.

Maintenance
Typically a service contract with six-monthly or quarterly cartridge changes, driven by measured volume rather than time.
Replacement interval: roughly every 6 months, though volume matters more than time. More on cartridge intervals.
