Pure Drinking Water with Reverse Osmosis

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.

UV treatment systems are also available for an added layer of water purification.

Frequently Asked Questions – Water Treatment

What water treatment systems do you offer?

We install and maintain water softeners, filtration units, UV sterilizers, and conditioning systems tailored for homes and pools. Discover how we integrate these with heating solutions on our Hot Water Systems page.

How often should water filters or softeners be serviced?

Filter cartridges typically require replacement every 6–12 months, while softener resin and salt replenishment depend on usage. We recommend annual servicing—check our Central Heating page for combined maintenance options.

Can water treatment improve pool and plumbing performance?

Absolutely. Treated water prevents scale buildup, prolongs equipment life, and enhances pool clarity. For pool-specific solutions, see our Pool Heat Pump installation service.

Is treated water safe to drink and swim in?

Yes—when systems are correctly maintained. According to the U.S. Environmental Protection Agency’s WaterSense program, certified filters effectively remove contaminants and pathogen risks.

How long does installation take?

Domestic installations typically take 1 day, while complex systems—like combined softener, UV, and filtration—may take 2–3 days depending on layout and plumbing access.

Do you offer ongoing maintenance plans?

Yes. We provide tailored service contracts including periodic inspections, filter changes, resin cleaning, and UV lamp replacements to ensure optimal performance year-round.
