Disclaimer
The short version: Tenselo helps you do the work. It does not do the work for you, and it does not carry the responsibility for it.
Design aid, not a design authority
Results from Tenselo are engineering calculations produced from the inputs you supply and the assumptions shown on each result. They are a starting point for a competent person, not an approved design.
A qualified engineer, or the appropriately licensed trade, must review and sign off any design before it is built or installed.
Product data
Product and performance data is taken from manufacturers’ published material and is reproduced in good faith. Manufacturers change their ranges, their data and their part numbers.
Confirm the exact model, trim, materials and NPSH with the manufacturer or their selection software before you order.
Standards
References to AS/NZS and other standards indicate the method a calculator follows. They are not a statement of compliance, and they do not replace reading the standard.
Local conditions
Climate, soil, water quality and regulatory requirements vary by location. Where Tenselo uses a regional default it says so on the result. Check it against your own site data.
