Before buying a new tap, explain how to use the Water Rating website to check its water efficiency. Specifically, what information is required to search for a tap in their product database, what do the star ratings mean for taps, and what is the highest available star rating for taps?
Navigate to 'waterrating.gov.au'. Go to the 'Consumers' section. Navigate to the 'Water saving tips' page. Identify the specific details required to search for a product in the database (e.g., product registration number, product type, brand, model name). Determine what the star ratings signify for taps and the highest available star rating for taps. Synthesize the process and information into a concise answer.
State that searches in the product database can be conducted using the product registration number, product type, brand, or model name. Explain that the website provides star ratings (e.g., 3 to 6 stars) to indicate water efficiency. Specify that the highest available star rating for taps is 6 stars. Do not attempt to log in to the industry registration database. Do not attempt to search for a specific product, but rather explain the *process* and *meaning* of the ratings based on the website's guidance.
