Toilet Repair in New Hampshire

Weighted across 436,947 occupied homes. Separately, 71% of the state’s 481,512 housing units — a wider universe, because it includes vacant ones — were built before 1990, which is before the Energy Policy Act of 1992 set a 1.6 gallon flush maximum.

Source: US Census Bureau, American Community Survey 5-year estimates, tables B25003 (tenure) and B25034 (year structure built), 2023 release. Flush volumes: US EPA WaterSense, tank-type toilet supporting statement.

A state average hides the thing that matters. Of the 127 towns we route in here, 32 are mostly pre-1990 housing and 5 are mostly post-1990 housing; on tenure, 86 are strongly owner-occupied and 5 are renter-heavy.

The two are close to independent of each other, so an old town is not reliably an owning town or a renting one. That is why every town page below carries its own pair of figures rather than inheriting these.

The fault list does not vary by state. A running tank is the flapper or the fill valve, and EPA publishes a ten-minute test that tells them apart. Water at the base is four different faults, one of which is condensation and not a leak at all. A fixture that rocks is the one that causes the seal failure you will meet later.

What varies by town is who fixes it. In a rented home the toilet is normally the landlord’s repair, and in the towns above that is a large share of households.

Checking a credential in New Hampshire

The authority is the New Hampshire Office of Professional Licensure and Certification, Mechanical Safety and Licensing Board. New Hampshire licenses plumbers but publishes no online licensee search, so verification means contacting the office directly.
