Toilet Repair in Thornton, CO
In Thornton the housing is mostly newer — just 27% predates 1990 — and 78% of households are owner-occupiers.
Short version
78% of occupied homes in Thornton are owner-occupied and 22% are rented, which is close enough to even that the first question is which you are. A landlord is generally responsible for a fixture in a tenancy; an owner is not. With most homes built since 1990, the fixture is probably already a 1.6 gallon one and its age is unlikely to be the fault.

What the age of Thornton’s housing suggests
Only 27% of housing units in Thornton were built before 1990. In a town like this the interesting question is not how much water the fixture uses but why a relatively new one is misbehaving.
Usually the answer is the flapper or the fill valve, both of which wear on a schedule of their own regardless of how new the house is.

What is actually wrong with it
Most calls are one of five things, and the useful first step is deciding which. Three of them — running, a weak flush and no flush at all — live inside the tank. The other two, a leak at the base and a rocking fixture, are underneath it and are related to each other.
Ask them to name the fault before they name the price. “The toilet needs replacing” is not a diagnosis; “the flapper seat is pitted and will not hold a new flapper” is, and it happens to be a common one.
