Scale Reduction System Service

A scale reduction system service keeps your existing limescale protection working as it should. The visit checks condition, performance and settings, then restores the system so it can help protect pipework, taps, showers and hot water equipment from scale-related wear.

More information

What the service covers

A practical service for installed scale reduction systems, tailored to your water conditions and how the property is used. Typical work includes:

  • Visual inspection for leaks, corrosion, damage and correct pipework configuration
  • Checking isolation valves, bypass arrangements and flow direction
  • Cleaning or replacing cartridges, media or dosing components where applicable
  • Testing operation and verifying performance indicators
  • Checking for restrictions to flow and signs of scale build-up at key outlets
  • Basic water checks and advice on realistic outcomes for your water type
  • Clear notes on what was done and any recommended follow-up work

When this service is right for you

  • You have a scale reduction system installed and want it maintained properly.
  • You are noticing reduced shower performance, kettle scaling, or frequent tap and valve issues.
  • You have a boiler, unvented cylinder or other hot water equipment you want to protect.
  • You are a landlord or facilities contact who needs a reliable maintenance routine and straightforward reporting.

What happens during the visit

The engineer will identify the type of scale reduction system you have, check the installation, then assess how it is performing against your current household demand. Where the system uses serviceable parts, these are cleaned, refreshed or replaced as needed, then the unit is checked for correct operation. You will be told what has been found, what has been completed, and what to expect next.

Aftercare and ongoing value

You will get practical guidance on service intervals, warning signs to watch for, and any improvements that would make the system more effective. If the system is undersized, poorly positioned, or not suited to your water conditions, you will receive clear options for putting that right. Ongoing servicing helps maintain flow, reduce scale-related callouts, and support the efficiency of hot water and heating equipment.

Frequently Asked Questions

What types of scale reduction systems can be serviced?
Most domestic scale reduction devices can be assessed and serviced, including units with replaceable cartridges or media and non-salt scale inhibitors. If you are unsure what you have, a quick check of the unit and pipework usually confirms it. You will be advised if parts are required before work proceeds.
Will a scale reduction system stop limescale completely?
It depends on your water hardness and the type of system installed. Many systems reduce scale build-up and make it easier to manage, rather than removing hardness minerals entirely. You will be given realistic expectations based on what is fitted and how the property is used.
How often should a scale reduction system be serviced?
Service frequency varies by device type, water conditions and usage, but an annual check is a common starting point. Systems with cartridges or dosing components may need attention more often. The engineer will recommend an interval that matches your setup.
Can you service the system if water pressure or flow is low?
Yes, the visit includes checks for restrictions, partially closed valves, blocked strainers, or issues around the unit that can affect flow. If low pressure is caused by something else in the plumbing, you will be told what the likely cause is and what the next step should be. Any follow-on work can be quoted separately.
Do I need to turn off the water for this service?
Some checks and component changes require the water to be isolated briefly, but disruption is usually kept to a minimum. You will be talked through what needs to happen before anything is shut off. If the system has no isolation points, options will be explained.
