Installation & Valve Compatibility Check

Answer a few quick questions and we will tell you whether you can continue with the standard form or need to complete the 2 Minute Compatibility Check first.

Step 1 of 10
What would you like to check?
Choose the option that best matches what you need.
Are you replacing an existing hot water system?
This helps us work out whether this looks like a standard replacement or may need extra parts.
Are you replacing the same hot water system, identical make and model?
If yes, the valve kit will be recommended. If not, it will be required at the end.
Is it going in an existing location?
Existing location means the new system is going back into the same general installed position.
Where is the system located?
If it is outside, continue. If it is inside or under a house, the 2 Minute Compatibility Check must be completed first.
Are you changing system type, electrical connection type or needing to extend your electrical connection?
If yes, we will advise at the end that an electrical extension or new circuit may be needed, or you can organise your own electrician.
Do any site access issues apply?
If any access issue applies, direct them to the 2 Minute Compatibility Check first. If none apply, continue with the form.
Does your current installation meet current compliance requirements?
If no or unsure, we will recommend a valve kit or additional works as the safer starting point.
