If you've been in Tenerife more than two years, there's a good chance you've already replaced a kettle, called out an engineer for a boiler that "just stopped working," or watched a washing machine slowly give up the ghost. And here's what nobody tells you when you move here: it wasn't a coincidence, and it wasn't bad luck. It was your water.
The Water Problem Nobody Warned You About
Tenerife doesn't have rivers. It doesn't have reservoirs in the traditional sense. Almost all of the island's domestic water comes from desalination plants — industrial facilities that take seawater and strip out the salt. What's left is then treated with chlorine and pumped into your home.
The result? Water that is technically safe to drink, but chemically brutal on everything it touches. It's loaded with dissolved minerals — calcium, magnesium, bicarbonates — that don't evaporate when the water does. They stay behind. They build up. And over months and years, they destroy things from the inside out.
That orange bar isn't a typo. Tenerife South has some of the hardest tap water in all of Europe — two to three times harder than what you were used to in the UK. Your appliances were never designed for it.
"After moving from Manchester, my brand new kettle was ruined in four months. I thought it was faulty — Adam told me within thirty seconds what the actual problem was."
— Janet, British expat, Costa Adeje (2023)What Limescale Is Doing to Your Home Right Now
Limescale isn't just an aesthetic problem. It's an insulating layer of rock that forms on every heated surface it touches — and heating elements have to work harder and harder to push heat through it, until eventually they can't cope at all.
The Maths That Changes Everything
Here's where most people have their lightbulb moment. Not when they hear about limescale — but when they actually add up what it's cost them since they moved to Tenerife.
And that's before you factor in the hassle of sourcing appliances in Tenerife, waiting for engineers, and living without hot water or clean clothes while things get sorted.
The Fix: Three Systems, One Problem Solved
The good news is that once you filter Tenerife's water, the problem stops. Full stop. Limescale can't form from water that doesn't carry the minerals that cause it. Here's what Adam and Max install — and which one is right for your home.
Under-Sink Carbon Filter
Removes chlorine taste and odour. Protects your kettle and coffee machine. Clean, great-tasting water from a dedicated kitchen tap. Perfect for renters or smaller budgets.
Reverse Osmosis System
5-stage filtration removes 99.9% of contaminants — limescale, chlorine, heavy metals, dissolved salts. Includes remineralisation cartridge and dedicated tap. The most popular choice.
Whole House Water Filter
Filters every drop of water entering your property — every tap, shower, appliance. The only system that protects your washing machine, boiler and dishwasher. One installation, total protection.
Adam and Max are based in Tenerife South. Every installation is done by their team, every service call is answered in plain English, and every system comes with lifetime support as standard. No middlemen, no subcontractors, no surprises.
