Not that long ago, I settled a dispute with a tenant about high water usage and leaking toilet flush. They never informed the agent as they haven't "noticed" it. Long story short, ended up with a water usage bill of over $500. Watercorp said it's not a hidden leak so won't accept the leak allowance application. In the end, I agreed to cover 20% + plumber costs and the tenant pay for the rest. I was thinking if I should just install smart meters in all the IPs so I get near real-time usage and be on the look out for leaks. It wasn't a huge amount this time around but I was reading about stories of bills for several thousand dollars and water company did nothing. The official smart meters are still on trial in some remote locations so it has to be something after the main water meter. Any thoughts?
