Reliable Water Filtration & Treatment Systems
At 100% Plumbing, we offer a full range of water treatment solutions to ensure clean, safe and efficient water throughout your home. Whether it’s a simple filter or a full purification system for a borehole, we tailor installations to your needs.
Pure Drinking Water with Reverse Osmosis
We install reverse osmosis systems that deliver purified water straight to your kitchen tap or fridge. These units eliminate nitrates, bacteria, and impurities—giving you fresh, safe drinking water without needing to buy bottled water again.
Water Softeners & Scale Protection
Living with hard water? We fit softening systems that protect your pipes, boilers and appliances from limescale damage. Our domestic and industrial softeners run on coarse salt, which we can deliver directly to your home.
Looking for a low-maintenance solution? As official distributors of Hydro Water products on the Costa Blanca North, we also offer simple, cost-effective anti-scale devices for your home or swimming pool.
UV treatment systems are also available for an added layer of water purification.
