Don’t know your rate? Use $6 per 1,000 gallons (rough placeholder) and adjust later.
If checked, head to the leak check.
How to find your rate: Look for “unit cost”, “rate”, “$/CCF”, or “$/1,000 gallons” on your bill.
How to estimate flow: Check inside the tank lid for gpf or look up your model.
WaterSense toilets are 1.28 gpf or less [1]. A drip per second wastes 3,000+ gallons/year [2].
