I'm building a new home and just saw that my taps are connected to each other, saw my neighbors taps they seems to be seperate as normal, should I be concerned
Is this normal or do I need to report this to Yarra Valley water, Please advise, I've attached the image below
Could be for line testing, could be for flushing the recycled lines, could be for a number of things, but as you're building im expecting one of those lines isnt actually connected upstream yet, or has the incoming meter isolated (otherwise that is a no-no).
Ask your builder or builders plumber what they are testing by doing that.
