That means limescale in the kettle, chalky glass shower screens, poor lather on soap, and, most expensively, scale building silently inside your boiler, cylinder, radiators and pipework. Back to home What it isFull water softener installation, supply and fit, or install of a unit you've already bought. Whole-house softening with a hard-water drinking bypass to the kitchen sink, proper drain arrangement, non-return protection and tidy pipework. Who it's forHomeowners across Broad Town, Royal Wootton Bassett, Marlborough, Calne, Swindon and the surrounding villages fed from the chalk aquifer that supplies most of this part of Wiltshire, genuinely hard water throughout. When you need itAny time. Especially worthwhile before a new boiler or unvented cylinder installation (scale is the biggest killer of both). Also a common upgrade during a kitchen or utility refit while the pipework's exposed. Why professional mattersScale robs efficiency, blocks heat exchangers, clogs shower heads and eats appliances. A softener is the cheapest whole-house upgrade against it, and it's obvious the day it's turned on. Our preferred brand ## Wash Water domestic softeners, supplied & installed Wash Water is the domestic water softener brand we choose to supply and install for our customers across Wiltshire. They're built for hard-water areas like ours, come with a strong manufacturer guarantee, and hold the independent approvals that matter: NSF certification, WRAS approval, UKCA, and Earth Safe Technology. Wash Water don't operate a formal installer accreditation scheme, so we won't claim one. What we will say is this: after years of fitting different makes, Wash Water is the range we trust for reliability, service life and honest performance, and it's the brand Ben personally recommends when a customer asks what he'd put in his own home. - Compact through to full-size cabinet models - Manufacturer's 7 & 2 year guarantee - NSF certified & WRAS approved product - Sized, sited & plumbed in by Ben personally The cost of leaving it ## What happens when it's ignored Ignoring hard water is a slow tax on every piece of plumbing in the house. Risks & escalations - Scale in the boiler heat exchanger raises flow temperatures, cuts efficiency and eventually cracks the exchanger. - Unvented cylinders scale up fast; the immersion element goes first, the cylinder second. - Combi boiler DHW plate heat exchangers scale within a few years and produce weaker, cooler hot water at the tap. - Kettles, dishwashers, washing machines and shower heads all shorten their working life in proportion to how hard the water is. - Poor lather means you use more soap, shampoo and detergent, a small but permanent tax. Common mistakes - Buying a softener online and letting a general handyman fit it. Water Regulations exist for a reason. - Softening the drinking-water tap. Softened water is fine, but a hard-water bypass to the kitchen sink is standard best practice. - Skipping the correct drain arrangement. Softeners need a properly designed drain and non-return protection. - Ignoring the salt level. Modern softeners tell you; check every month. Ten minutes of monthly salt-topping in exchange for cleaner water, lower bills and a longer-living boiler is a very easy trade. Our process ## A clear, five-step system, no surprises - Step 1 Site survey Mains route, current stopcock condition, space for the softener, drain access and where a drinking bypass is best fitted. - Step 2 Softener selection Right unit for the household size, water hardness and flow rate | supply and fit, or install of your chosen unit. - Step 3 Pipework and install New mains isolation, bypass loop, softener plumbed in with correct fittings, drinking-water bypass to the kitchen tap. - Step 4 Programming and salt-fill Softener programmed for local water hardness, salt loaded, first regeneration cycle observed. - Step 5 Test, walk-through and warranty Test the softening at the tap, hardness-test kit left with you, walk-through of maintenance and warranty registered. The benefits ## Concrete outcomes, not vague promises No more limescale Kettles, taps, shower screens, tiles | the constant cleaning battle stops. Boiler and cylinder protected The biggest cause of premature boiler and cylinder failure in Wiltshire, removed at the mains. Lower detergent use You'll notice within a fortnight | soap lathers, less shampoo, less washing powder. Softer skin, cleaner hair The one benefit almost every household mentions unprompted after installation. Longer appliance life Dishwashers, washing machines and heating elements last measurably longer on softened water. Regulations-compliant install Proper isolation, non-return protection, drain arrangement and hard-water bypass | done right. In detail ## The technical stuff, explained straight Where the theory meets the van. Materials, methods, brand differences and the specific situations we deal with week in, week out across Wiltshire. ### Wiltshire water and why it's so hard Most of north and east Wiltshire, including Broad Town, Royal Wootton Bassett, Marlborough, Calne, Swindon and the surrounding villages, sits on the chalk aquifer. That gives excellent-tasting drinking water but very high calcium and magnesium content, technically 'hard' or 'very hard' water. It's healthy to drink; it's punishing on plumbing. A softener uses an ion-exchange resin (regenerated periodically with salt) to swap the calcium and magnesium ions for sodium ions, giving genuinely soft water throughout the house. ### Whole-house softening with a drinking-water bypass Best-practice installation keeps one hard-water tap in the kitchen (typically the cold tap on the kitchen sink) for drinking, cooking and filling the kettle, some people prefer the taste of the natural hard water, and there's a marginal sodium argument for pregnancy, infants and low-sodium diets. Everywhere else, showers, baths, hot taps, appliances, boiler, cylinder, runs on softened water. That's the arrangement we fit as standard unless you tell us otherwise. ### Sizing and unit selection Softeners are sized on household water use and local hardness. Under-sized softeners regenerate too often (using more salt) and can't keep up with peak-demand periods. Over-sized units cost more up front and take longer between regenerations (which risks bacterial growth in the resin bed). We'll size to your household honestly. Metered / demand-based softeners (Harvey, Kinetico, Culligan, Monarch) are the modern standard, timer-only units are largely obsolete. ### Regulations and best-practice fittings Water Regulations require an approved installation with an AA air-gap or equivalent backflow protection to the drain, a proper isolation and bypass arrangement, and non-return protection to prevent softened water back-feeding the incoming main. We fit all of that as standard; it's what protects your household water supply and stops any risk of contamination. ### Maintenance | what you actually need to do Modern softeners are close to fit-and-forget. Top up salt every few weeks (a low-salt warning is standard on most units), keep the salt bin lid closed, and let us test the softener on your annual boiler service. Resin beds last 10–15 years typically; brine valves and controls are user-serviceable and cheap to replace when needed. FAQs ## The questions we're asked most Can't see yours?
