Water Filtration & Treatment Done Right

Cleaner, scale-free water throughout your home that protects boilers and appliances, reduces cleaning time and delivers better-tasting drinking water — that’s the outcome of correctly specified water filtration and treatment. Pro Plumbers Ltd installs whole-house softeners, under-sink filters and reverse-osmosis systems across Sevenoaks and nearby Kent towns. We size and position systems to match property type — from period cottages and oil-heated rural homes to modern flats — and carry Gas Safe, OFTEC and Worcester/Vaillant approvals to ensure safe, warranty-friendly installations.

How It Works

01

Site survey & water test

Engineer inspects pipework, boiler type and water usage, then runs a hardness and contaminant test to determine the right system.

02

Specification & quote

We recommend whole-house or point-of-use solutions, show placement options, explain maintenance needs and provide a written quote.

03

Install, commission & advise

Installed to manufacturer and Gas Safe/OFTEC standards, systems are commissioned on-site, user-trained and registered for warranty.

Why Choose us for Water Filtration & Treatment?

Protects boilers & appliances

Reducing limescale improves heat transfer and lowers failure risk — extending the life of boilers, washing machines and dishwashers.

Tailored system for your property

We match softeners, filters or reverse osmosis to water test results and property type, from gravity-fed systems to mains-fed modern builds.

Trusted, compliant installations

Gas Safe and OFTEC-registered engineers with Worcester and Vaillant accreditations deliver safe, warranty-friendly installs and a 1-year workmanship guarantee.

Whole-house softeners are fitted where limescale affects radiators, valves and cylinder surfaces. These units treat all incoming water and regenerate automatically with salt; sensible siting and correct pipework isolation protect boiler controls and immersion elements. For oil-heated rural properties we co-ordinate with OFTEC-registered engineers to ensure compatibility with gravity-fed tanks and non-standard cold-water supplies.

Point-of-use and drinking-water options include under-sink carbon filters and reverse-osmosis units that remove chlorine, sediment and taste-impairing impurities. We position point-of-use units so installation is serviceable and food-safe, and give clear maintenance guidance — salt top-ups for softeners and cartridge or membrane change schedules for filters and RO systems.

Frequently Asked Questions

If you see scale build-up on taps and showerheads, notice white residue on kettles or get frequent limescale-related boiler faults, a softener will help. We perform a hardness test during the site survey and advise whether whole-house treatment or localised filtration is the better solution.

Had the pleasure of having my heating system replaced by Mikey. He was really helpful and informative with any questions I asked. He was also very clean and professional, would highly recommend these guys, especially Mikey.

I called up Dave to fix a leaking pipe under my sink. He was so professional, worked efficiently, and cleaned up afterward. The price was exactly as quoted. I’m very satisfied with the service and could not be happier with the service.
