Reverse Osmosis Installation in Valencia

Why Valencia's Water Needs Filtering

The water reaching taps in Valencia city and its metropolitan area passes all health checks and is safe to drink, but it's hard — with a fair amount of calcium carbonate — and chlorinated for transport. You notice it in the taste, in the white marks on taps, and in coffee makers and kettles scaling up sooner than expected.

A reverse-osmosis unit runs the water through several filter stages — sediment, activated carbon and an osmosis membrane — that trap limescale, chlorine and most dissolved solids. The result comes out of a separate tap next to the sink, ready to drink and cook with.

How the Installation Works

• We fit the unit under the sink, with no construction work or changes to existing plumbing
• We install a dedicated tap for the osmosis water
• We check the inlet pressure and the reject-water drain
• We explain when each filter will need changing

Maintenance: What Almost No One Tells You When Selling the Unit

“A reverse-osmosis system isn’t “install and forget.” The sediment and carbon filters get saturated, and the membrane loses efficiency over time — especially with the limescale levels we have here. If they’re not changed on time, water still comes out, but it stops being properly filtered, and there’s no way to tell just by looking.

That's why we track the installation date of every filter and let you know when it's time to change it — that's exactly what the HydroViva Care subscription covers, so you don't have to remember.

Reverse Osmosis or a Water Softener?

These are different services, and sometimes combined: reverse osmosis treats the water from one specific tap for drinking and cooking; the water softener treats all the water entering the home to protect pipes and appliances. Not sure which one you need? Tell us your situation and we'll clarify it, no obligation.

Worth knowing if someone at home has high blood pressure or a low-sodium diet: a resin-based water softener softens water by replacing calcium and magnesium with sodium, while reverse osmosis doesn't add sodium — if anything, it reduces it. In those cases, reverse osmosis in the kitchen is usually the better option for drinking water.
