Why Trenton homes get repiped
50% of homes in Trenton's covered ZIP codes were built before 1960 (50%, above the New Jersey figure of 38%). That ranks 17th highest of the 47 New Jersey cities we profile. Homes of that age were plumbed with galvanized steel, which rusts from the inside until pressure drops and the water runs brown.
23% of the housing predates 1940. Many of those homes have had partial repairs over the decades, so it's common to find copper or PEX spliced into old galvanized runs, and those joints are where leaks start.
In New Jersey: Older housing has cast iron drains, galvanized lines and lead service lines, which state law requires utilities to replace.
Permits
A repipe normally needs a permit and inspection from your city or county, and the written quote should say whether wall patching is included.
