TDS, pH, and Hardness: Understanding Your Water Hardness Test Report

RiverSoft | 23 August 2025

Does clear water always mean safe water? Not necessarily. Tap water may look crystal clear and smell fine. But once the water test report arrives, you’re suddenly staring at a page full of numbers and unfamiliar abbreviations. It’s no surprise that most people feel confused when trying to make sense of it.

But here’s the good news:

You don’t need a science degree to understand it. In this blog, we’ll break down a few of the numbers that truly matter for your skin, hair, and appliances.

How to Read a Water Test Report ?

Typical water test reports usually contain 20 different technical terms. They talk about a important parameters to define water quality. Here we will clarify one of the most important ones which affects water taste and affects your hair and skin

They are:

TDS (Total Dissolved Solids)
Total Hardness
and pH

If you understand these three values, everything about the water report will start to make sense.

Now, let’s begin with the first number: TDS

What is TDS in Water?

TDS (Total Dissolved Solids) is a measure of all the dissolved substances in your water. This includes minerals like calcium and magnesium, salts, metals and sometimes even pollutants. It's measured in ppm (parts per million).

So, why does TDS matter?

Mainly because it affects how your water tastes and how it interacts with your appliances and skin. For example:

Under 50 ppm: Water can taste flat or dull.
50 - 300 ppm: Water generally tastes fresh or balanced.
Above 500 ppm: Water may taste salty or metallic.

However, not all TDS is bad. If your TDS is high due to natural minerals… it might just affect taste or cause mineral buildup on taps and showerheads. However, high TDS from pollutants or nitrates can be a health concern.

How to mitigate the effect of high High TDS at Home?

A water softener can help prevent scale buildup on taps, tiles, and appliances, and make water gentler on your skin and hair by inerting hard salts and making the water suitable for non drinking purposes like showering etc. These products do no reduce the TDS, which can be reduced only by a reverse osmosis process like RO purifiers. RO purifiers are essential to reduce TDS above 500 to make water fit for drinking purpose.

What is Water Hardness?

Water hardness is the amount of calcium and magnesium dissolved in your water. These minerals are common in borewell and even municipal water.

Water hardness is classified as:

Soft: 0–60 ppm
Moderately Hard: 61–120 ppm
Hard: 121–180 ppm
Very Hard: 180+ ppm

While hardness doesn’t significantly affect the taste of water, it interferes with how soaps and shampoos work, leading to:

Dry skin
Hair breakage

Over time, it also causes limescale buildup on taps and appliances and reduces the lifespan of washing machines and geysers.

How to Reduce Water Hardness at Home

You can use a bathroom water softener or washing machine filter. The bathroom softener reduces hair fall, prevents skin damage, and reduces flaky scalp… while the washing machine filter protects fabric quality, and extends machine life - all with simple, no-plumber installation.

What is pH in Water?

The pH is a measure of how acidic or alkaline your water is, on a scale from 0 to 14. The ideal pH for drinking water is between 6.5 and 8.5. This makes sure water is safe to consume and non-damaging to your pipes or appliances.

Here’s why it matters:

Low pH (<6.5): Acidic water can cause corrosion and leaching of metals like lead or copper.
High pH (>8.5): Alkaline water may lead to a bitter taste and buildup in appliances.

Best Solutions for Unbalanced Water pH at Home

A pH balancer or hard water purifier can fix off-range pH, improve water quality and reduce plumbing damage.

What Your Water Hardness Test Results Are Telling You (and How to Fix It)

Once you understand how TDS, hardness, and pH work together, the real value lies in knowing what to do next. Here’s how to respond to common water test findings:

High TDS? Use a water softener for bathroom to reduce hardness-related issues like hairfall and dry skin.
To lower TDS, you’ll need an RO purifier so that water becomes fit for drinking purpose
Low pH ? Install a pH balancer or purifier to prevent rust and pipe corrosion.

Once you understand what's in your water, the solution becomes simple. All you need to do is choose the right product to protect your skin, your hair, and your home.
