About waterfilter.casa
Independent water filtration specialists serving the British and Irish community on the Costa Blanca
waterfilter.casa was founded with a straightforward mission: to help English-speaking homeowners on the Costa Blanca get clean, great-tasting water without the confusion, pressure, or inflated prices that often come with the water treatment industry. We are a small, local business that takes pride in doing things properly, and we have now helped over 500 homes across the region enjoy better water.
Our Story
How a passion for clean water became a business serving hundreds of homes across the Costa Blanca.
When we first moved to the Torrevieja area, like many British expats, we were struck by how different the water is compared to back home. The taste was heavily chlorinated, the showers left white scale on every surface, and our kettle seemed to fur up within a matter of days. We bought bottled water for drinking, but that meant lugging heavy crates from the supermarket every week, spending hundreds of euros a year, and contributing to the mountain of plastic waste that is such a problem on the Mediterranean coast.
We started looking into water filtration and quickly realised that the information available was either overly technical, clearly biased towards a particular brand, or simply not relevant to the specific water conditions on the Costa Blanca. The local Spanish companies we contacted struggled to explain their products in English, and the few English-speaking companies we found were pushing overpriced systems with aggressive sales tactics.
There had to be a better way. We spent months researching water treatment technology, studying the specific composition of the water supply in the Torrevieja area, and understanding the local regulations that affect what systems can be installed. We trained with water treatment manufacturers, earned relevant certifications, and tested dozens of systems in real homes across the Costa Blanca.
The result was waterfilter.casa. A business built on the principle that people deserve honest, clear advice about their water, professional installation at a fair price, and reliable after-sales support. We are not tied to any single manufacturer, which means we recommend the system that genuinely suits your situation, not the one that gives us the biggest margin. Five hundred homes and counting have trusted us to sort out their water, and we intend to keep earning that trust one installation at a time.
Our Values
Four principles that guide everything we do. They sound simple because they are.
Independent
We are not tied to any single brand or manufacturer. That means we recommend the system that genuinely suits your water, your home, and your budget. If a cheaper system does the job, we will tell you that. If you need something more powerful, we will say so. Our recommendations are based on your actual needs, not our profit margins.
Expert
Water treatment is all we do. We understand the specific water conditions on the Costa Blanca, the local plumbing standards, the regional regulations, and the concerns that matter most to British and Irish homeowners living in Spain. Every system we install is specified based on actual experience with local water conditions, not guesswork.
Local
We live and work on the Costa Blanca. We are not a call centre in another country or a franchise that disappears after the sale. When you need us, we are here. We know the area, we know the water, and we know the community. Our reputation in the local British and Irish expat community is everything to us.
Trusted
Over 500 homes have trusted us with their water. We back every installation with a full 2-year warranty covering parts and labour. We turn up when we say we will, we do what we say we will do, and we are there if anything needs attention after the installation. Ask around on the local Facebook groups and forums. Our reputation speaks for itself.
Credentials and Experience
We take our expertise seriously. Here is what backs up our advice and our installations.
Water Treatment Training
Our team holds manufacturer-certified training on the full range of systems we install, including reverse osmosis, whole house filtration, under sink filters, and water softeners. We stay current with the latest filtration technology and attend regular industry training to ensure our knowledge is up to date. This is not a sideline or a hobby. Water treatment is our full-time profession.
Local Knowledge
We have installed systems in hundreds of homes across Torrevieja, Orihuela Costa, Guardamar, Quesada, and the surrounding area. This gives us an unparalleled understanding of the local water conditions, including how they vary between urbanisations, how they change seasonally, and what works best in different types of property from apartments to villas. No amount of online research can replace hands-on experience with the actual water in your specific area.
Regulatory Compliance
We understand the local and regional regulations that apply to water treatment systems in the Valencia region. This includes the specific rules around traditional water softener installations and brine discharge, which many homeowners and even some installers are unaware of. Every installation we carry out complies with current regulations, protecting you from potential issues now and in the future.
After-Sales Support
Our relationship with you does not end when we walk out the door. We provide ongoing support for filter changes, maintenance queries, and any issues that arise with your system. We maintain records of every installation, including system specifications, so we can provide informed support whenever you need it. Our 2-year warranty is genuine and we honour it without quibble.
By the Numbers
Since we started, we have filtered over 500 homes across the Costa Blanca. Every single installation comes with a full 2-year warranty covering parts and labour. We cover a 30km radius from our base in Torrevieja, reaching from Guardamar in the north to San Miguel de Salinas in the south, and from the coast inland to Quesada and beyond.
