Guides for each Austra system
Crystal
7-stage on its own. Added to Home Guard, there's no separate sediment pre-filter.
Rain Guard
3 cartridges + 48 W UV lamp. We recommend professional service.
Before any filter change
Turn off the water supply, and the power where instructed, before you start.
Relieve pressure only as shown in the manual for your system.
Don't open or change plumbing, electrical or UV equipment.
When to stop
Stop the job and request service if…
A DIY change should only ever proceed when everything matches the guide. If any of these apply, stop where it is safe to do so and send us a service request — converting to a professional visit is always the right call.
- A valve will not close, or will not close fully
- A filter housing is cracked, worn or damaged
- Plumbing or fittings move when you touch the housing
- Electrical components are wet, or near water
- A leak continues after the change
