Minol advertises the submetering services as helping to detect leaks but they won't issue any sort of alert and, despite any admin fees charged, usually treat the end customer as a third wheel check-writer. For a company that takes bi-monthly utility bills and converts them to monthly bills with additional 10% in various admin fees you'd think they'd be more responsive to customers who pay those fees.
I've had issues with a recent bill arriving 4-5x higher than normal with no contact from the apartment building management or flags from minol as to what's going on, just a demand to pay. The company has daily reports from the type of submeter installed in my unit.
After having my property manager obtain those records I could see there are days with 600 gallons of water being reported instead of the normal
