Water Treatment

Whole-House Water Filter Installation

Whole-house water filter installation fits a filtration unit to your incoming mains supply, so water is treated before it reaches taps, showers and appliances. It is a practical way to improve everyday water quality, reduce sediment and chlorine, and help limit limescale build-up that can shorten the life of pipework, boilers and white goods.

More information

What whole-house water filter installation includes

A whole-house system is designed around your water supply, property layout and usage. Installation typically covers:

  • A check of your incoming supply, existing stop tap, pressure and available space
  • Advice on the right filtration approach for your goals, such as sediment removal, carbon filtration for taste and odour, and limescale reduction options
  • Selecting a suitable location for access and future cartridge changes
  • Installing isolation valves and secure mounting where required
  • Connecting the filter into the incoming mains, with careful pipework alterations
  • Leak checks, pressure checks and commissioning
  • A clear handover on operation, maintenance intervals and what to monitor

When this service is most useful

This service is a good fit if:

  • Your water has a noticeable chlorine taste or odour
  • You see grit, sediment or discolouration from taps
  • You are in a hard water area and want to reduce limescale build-up
  • You want to protect showers, taps, boilers and appliances from scaling and debris
  • You manage a rental or small commercial property and want a consistent, low-hassle setup

How installation is carried out

After confirming the best system for your needs, the incoming main is isolated and the filter is fitted inline at an agreed point. Pipework is adjusted neatly to allow safe access for maintenance, and key valves are added where needed to make future servicing straightforward. The system is then tested, flushed as required, and left running with guidance on how to use it.

After installation: maintenance and ongoing value

Most whole-house filters need periodic cartridge or media changes to keep performance consistent. You will be advised on realistic change intervals based on your water conditions and usage, plus any signs that a service is due, such as reduced flow or returning taste and odour. If you want ongoing support, servicing can be scheduled to keep the system working as intended.

Frequently Asked Questions

Will a whole-house filter affect my water pressure?
A correctly sized system should maintain good flow for normal household use. If pressure is already low, the filter choice and pipework layout need to be planned carefully to avoid unnecessary restriction.
Do I need a filter, a water softener, or both?
Filters target sediment and chlorine, while softeners treat hardness minerals that cause limescale. Many homes use one or the other, and some benefit from a combined approach depending on water quality and what you are trying to improve.
Where is the filter installed?
It is usually fitted on the incoming mains after the stop tap, where it can treat all cold water feeds. The final position depends on access, pipework layout and space for future cartridge changes.
How often do the cartridges need changing?
Change intervals vary by filter type, water quality and usage. Many homes replace cartridges every few months to a year, and you will be guided on a sensible schedule for your system.
Is whole-house filtration the same as a drinking water filter?
Whole-house filtration treats water to the whole property, mainly for general use, showering, and appliance protection. If you want the highest level of drinking water treatment, a separate under-sink filter can be added at the kitchen tap.
