Water Treatment

115 products

If you’re choosing water treatment, start with the problem you need to deal with - scale, taste, or debris in the supply. A water softener suits hard water and limescale control. A water filter is the better call for sediment or a single outlet, while whole-house kit covers every draw-off point. Under sink water filter options are usually the neater choice when you only need drinking water sorted.

For the Trade

Start with the space you’ve actually got and how the kit will be used, because that usually sets the spec before you get into finishes or extras. A compact under sink water filter works when you only need treated water at one outlet and cupboard room is tight. A whole house water filter or water softener comes into play when the job needs treatment across the full supply. The awkward jobs are the ones where the unit is too bulky for the cupboard or the pipe run leaves no sensible service access. That’s where the choice gets narrowed down.

Water Treatment Types and Layouts

The first split is usually between a water softener and a water filter. Softeners suit jobs where scale is the problem and the system needs protecting. Filters make more sense when you’re dealing with debris, taste, or general mains quality.

A water treatment system can cover more than one job. The trade-off is more to service later and less simplicity on the install. Most mistakes come from fixing the symptom and leaving the real complaint in place. If you’re working back through Plumbing, that’s usually where the spec starts to narrow.

What to Check Before You Buy

What you buy comes down to the fault you’re dealing with and how much of the supply needs treating. A water softener is the usual call where limescale is the problem. It won’t suit a job focused on taste, sediment, or broader water treatment.

A whole house water filter covers every outlet, so it fits when the full supply needs attention. An under sink water filter is the neater pick when only one draw-off matters and space is tight.

If access is awkward, think ahead to Access Panels. If you’re tying into the waste side, Waste Pipe & Fittings usually need sorting at the same time.

Useful Alongside Water Treatment

Once the main kit is chosen, the next call is usually what needs opening up, boxed in, or finished around it. Access panels matter here. If you can’t get back to the valve or cartridge without damage later, the install isn’t right.

Waste pipe and fittings are the other bit that gets missed until the end. That can slow the job down if the outlet position hasn’t been thought through early. Keep the surrounding finish in mind as well. The cleanest water treatment install leaves proper access and a clear route for the pipework, not a setup that needs revisiting because the last fixings went in too soon.
