To identify if a water outlet has a mains water or rainwater connection, there are specific labelling and colour codes to look for. Rainwater outlets should be labeled and marked with black and green colours. For underground pipes, it will typically be a black pipe with a green stripe. Outside taps should have a plaque indicating that it is a non-drinking water source, usually green with black text.
It’s important to note that most mains water taps won’t have any labelling. If there’s no label, it’s likely a mains water connection. However, it’s always a good idea to confirm with the owner or building authority to be sure. When ordering a rainwater harvesting system, there should be sticker kits or labelling packs available to mark the outlets correctly. If these are not provided, you can contact the manufacturer to obtain them. It’s essential to label outlets, especially if there are children living in the property, to prevent accidental consumption of rainwater.
