Landlord cannot identify which tenant's toilet is causing excessive water usage because water bills are commingled and tenants deny responsibility.

Workarounds Described

• asks tenants to confirm it's not their toilet
• suspects a toilet but cannot prove it

Implied Software Gaps

• Fixture-level water monitoring device that records usage locally without Wi-Fi

ToiletFlow Tracker

A non-WiFi battery-powered water meter that attaches inline to a toilet supply line to measure gallons used. It uses a simple digital display or local Bluetooth to show usage, enabling landlords to identify exactly which toilet wastes water without internet or complex installation.
