What Does a Water Test Actually Test For?

A water test isn't a single number. Here's what we actually measure at your tap and why each one matters.

Why a Test Isn't One Number

Water quality isn't a single score. It's a profile. A good test measures several things, because the right solution depends on which of them are present and at what level. Here's what we measure at your tap:

The Common Parameters

Hardness

How much calcium and magnesium are in your water. The single most common issue in Central Valley homes — it drives scale, spots, and dry skin.

Chlorine & Chloramine

Disinfectants added by the city. They keep water safe in the pipes but can leave a taste and odor you may want to reduce at home.

pH

Whether your water is acidic or alkaline. Out-of-range pH can affect taste and, in extreme cases, plumbing.

Total Dissolved Solids (TDS)

A broad measure of everything dissolved in your water. High TDS doesn't mean unsafe, but it tells us how much total dissolved content is there — useful for deciding if RO makes sense.

Iron & Metals

Iron causes orange stains. Other metals can come from older plumbing. We test for these when your water shows signs.

What the Results Tell Us

Each parameter points to a different solution. High hardness means a softener. Chlorine taste means a whole house filter. High TDS or drinking concerns may point to RO. The test connects the problem to the right system — that's the whole point.

Frequently Asked Questions

A professional on-site test typically measures hardness, chlorine, chloramine, pH, total dissolved solids (TDS), iron, and sediment/turbidity. It gives you a clear picture of what's actually in your water at the tap right now.
