Water filter replacements
Cartridges wear out. Change them on time and your system works as well as the day it was installed, with the same flow and the same taste.
How often
Every 6 to 12 months for most homes
The right interval depends on your water and your household. A big family on tank water will go through cartridges faster than two people on town water. We log your installation date and send an email reminder before each change, so you don't have to keep track.
Signs your filters are overdue
- Pressure or flow has slowly dropped off
- The chlorine taste or smell is back
- Spots and scale are reappearing on glass and taps
- It's been more than a year since the last change
An old sediment cartridge restricts water to the whole house, and spent carbon stops holding on to what it has already caught. Leaving filters in too long costs you more than performance.

FAQ
Replacement questions
How do I know which cartridges to order?
You don't need to. We keep the configuration of every system we install. If someone else installed yours, send us a photo of the housings and we'll identify them.
Do I need to turn the water off?
Only to the filters. Close the bypass valve fitted at installation and the rest of the house keeps running while you work.
Can I change them myself?
For most systems, yes. The cartridges are tool-free, and we include instructions plus a housing spanner for the larger whole house canisters.
The pressure didn't come back after a change. Now what?
Something else is going on, most often a valve that is not fully open or an issue upstream. Call us and we'll talk it through before anyone comes out.
Not sure when yours was last changed?
Send us your address and we'll check your service record and tell you exactly what's due.
