Define the measurement
Hardness concerns calcium and magnesium behavior and is often used to size and check softening. A TDS meter estimates dissolved material through conductivity. It does not identify individual substances or replace laboratory testing for a particular concern.
Use readings for the right decision
A softener can reduce hardness without sharply lowering TDS. A drinking-water membrane can change dissolved-solids readings, but that alone does not certify every contaminant claim. Ask for measurements connected to the specific equipment and desired outcome.
Keep sales demonstrations in perspective
A color change or number on a meter needs an explanation of method, units and limits. Do not accept a citywide average as the value at your home. Record untreated and treated sample points so future service can be checked with a meaningful comparison.
The raw well and backwash supply
On a Loxahatchee private-well property, keep the well, pump and existing treatment sequence in the same assessment. Photograph each stage in the direction of flow and label any sample point before the equipment. Describe whether the well also supplies irrigation and whether the household notices changes while other water is running. Raw-well testing and available maintenance flow can alter the proposed sequence. A municipal city report or a neighbor’s installation does not specify your well system.
