Water Softener Replacement

Water softener replacement is the straightforward way to restore reliable soft water when your existing unit is worn out, leaking, undersized, or no longer performing. A like-for-like swap or a planned upgrade helps reduce limescale build-up, protects pipework and appliances, and keeps water quality consistent across the property.

More information

What water softener replacement covers

A replacement is planned around your current setup and how your property uses water, so the new unit performs properly from day one. The service typically includes:

  • A check of your existing softener, incoming supply and available space
  • Advice on a suitable replacement unit and capacity for your household or site
  • Isolation of the water supply and safe removal of the old system
  • Connection to existing pipework, with checks to bypass and isolation valves
  • Installation of the new softener, set-up and commissioning
  • Testing for leaks and confirming softened water at key outlets
  • Practical handover on salt use, settings and basic upkeep

When this service is the right fit

Water softener replacement is most useful when you notice any of the following:

  • Limescale is returning on taps, shower screens or kettles
  • The unit is frequently regenerating, noisy, or showing fault codes
  • You have a leak, corrosion, or salt bridging issues that keep coming back
  • Your household size has changed and the system is no longer correctly sized
  • You are renovating a kitchen, utility room or plant area and want a neater install

What to expect during the replacement

Most replacements are completed in one visit, depending on access, pipe condition and whether any pipework changes are required. The old unit is isolated and disconnected, then the new softener is installed, aligned, and connected with leak checks throughout. Once fitted, the system is programmed and tested so you know it is softening properly before it is signed off.

After installation: keeping performance consistent

You will be shown how to top up salt correctly and what to watch for if performance drops. If your property has mixed outlets, you will also get clear guidance on which taps are softened and which should remain on the hard water supply. If you want ongoing peace of mind, routine checks can help catch leaks, settings issues, or consumption changes early.

Frequently Asked Questions

How do I know if my water softener needs replacing?
Common signs include limescale returning, frequent faults, leaks, or the unit struggling to keep up with demand. If the system is old or repairs are becoming regular, replacement is often more cost-effective.
Can you replace my softener with a different make or size?
Yes, as long as the new unit is correctly sized for your water hardness and usage, and fits the available space. Pipework may need minor alterations, which will be explained before work starts.
Will I be without water during the work?
There is usually a short period when the supply is isolated while the old unit is removed and the new one is connected. Where possible, downtime is kept minimal and you will be told what to expect before work begins.
Do I need a water hardness test before replacement?
A hardness check is helpful for selecting the right capacity and settings, especially if you are upgrading rather than swapping like-for-like. If you are unsure, the supply can be assessed as part of the visit.
What maintenance is needed after a new softener is fitted?
Most systems mainly need salt topped up and occasional checks to ensure the settings match your usage. You will be shown the basics and advised what changes might indicate a problem.
