any product needs to have passed astralian standards to be used on plumbing systems and needs to have the water mark. check with you own states authority of water supply/plumbing if they cant help should be able to put you in touch with some one who can help.
A product has to be properly tested and passed as the results of the device failing could bedamaging and without approval could end up getting you sued.
It might be a lenghty process but if the products as good as you think it might be worth it.
