Water Softeners

Whole-home limescale protection

Find the Right Water Softener for Your Home

A water softener removes the calcium and magnesium that cause hard-water scale, helping protect your boiler, appliances, taps and shower screens. Compare electric, non-electric and twin-cylinder systems for different household demands.

Start with Your Household Requirements

These routes are useful starting points, but final sizing must also account for water hardness, peak flow, bathroom use and installation space.

Household size is only the starting point

Check your hardness, bathroom demand, flow rate and available space before choosing. The buying guide explains each step clearly.

Twin-Cylinder Softeners

Alternating cylinders can maintain softened-water availability while one cylinder regenerates.

What to Check Before Buying a Water Softener

The best system is not automatically the largest or most expensive. It should match the hardness load and peak water demand of your home while fitting the intended installation position.

Water hardness

Harder water exhausts the resin capacity more quickly, affecting regeneration frequency and salt efficiency.

Peak flow demand

Consider bathrooms, showers and appliances likely to run at the same time—not only average daily usage.

Installation space

Allow for the cabinet, pipework, drain and overflow connections, plus access for salt refilling and servicing.

Running requirements

Check the required salt format, electrical supply, regeneration water use and ongoing maintenance.

Water Softener FAQs

What size water softener do I need?

Sizing depends on household water use, local hardness, number of bathrooms, peak flow demand and the capacity of the softener at that hardness. Occupant numbers provide a useful starting point but should not be used alone.

Will a water softener remove limescale?

An ion-exchange water softener removes the calcium and magnesium that create hardness, preventing new hard-water scale from forming in the softened supply. It is not an instant chemical descaler for existing heavy deposits.

What is the difference between electric and non-electric softeners?

Electric softeners use an electronic controller and require a power supply. Non-electric systems typically use a mechanical meter driven by water flow. Both can be demand-metered; suitability depends on the model, household and installation position.

Why choose a twin-cylinder water softener?

A twin-cylinder system alternates between resin tanks. This can provide softened-water availability while one cylinder regenerates, making the format useful for homes with continuous or higher demand.

Where can a water softener be installed?

Common locations include beneath a kitchen sink, in a utility room, garage or another position close to the incoming mains. The installation needs suitable inlet and outlet pipework, a drain connection, an overflow route and frost protection. Electric models also require power.

Can I drink softened water?

Many households use softened water throughout the home, but the appropriate drinking-water arrangement depends on installation design, household circumstances and applicable guidance. Some customers retain an unsoftened kitchen drinking tap or use a separate drinking-water filter. Ask your installer if you are unsure.

Does Regal Flow install water softeners?

Regal Flow does not provide an in-house installation service. We can advise on product requirements and may be able to introduce you to an independent installer, depending on your location.
