Water Softener Installation in Princeton, TX
Princeton is supplied by City of Princeton, which draws surface water. That one fact does more to predict whether a softener is worth it here than anything a salesperson will ask you on the phone.
The short version
City of Princeton supplies Princeton from a surface source. Surface water has had far less contact with rock, so it is more often soft enough to leave alone. Hardness is published annually by the supplier, and that one figure is what a softener decision should rest on.

Where the water comes fromSurface water in Princeton
This is a surface water supply, which matters for hardness: the water has not spent years in an aquifer dissolving calcium out of stone. Expect a lower figure than a neighboring town on wells.
City of Princeton serves 15,569 service connections. That is the system's own return to the EPA, as of the second quarter of 2026.

What to do with thatGet your hardness figure
The figure you need is already published: City of Princeton issues an annual water quality report, and hardness is one of the lines on it. It will be given in milligrams per liter. Softeners are sized in grains per gallon, and one grain is about 17 mg/L.
Then run the arithmetic: it tells you the capacity you need rather than the capacity you are offered. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
NearbyWhat other towns near Princeton draw
Source type is not uniform across a region. One of the nearby towns we route are on ground water while Princeton is on surface, which is why a hardness figure borrowed from a neighbor is worth very little.
