  • What Is TDS and Why Should You Care?
Total Dissolved Solids (TDS) is the total weight of all solids (minerals, salts, or metals) that are dissolved in a given volume of water, expressed in milligrams per liter (mg/L), or in parts per million (PPM)
The higher TDS level in the water, the more the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level

I bought one of these off-brand meters last week, and was surprised to find out thatour PPM is over 400. I'm gonna grab this one just to confirm the first one is giving legitimate readings. Thanks OP, repd

PS - any fellow SDers have any knowledge or experience in dealing with awful water? assuming these results come back the same, I'm going to have my neighbor test as well and then I guess the next step is to call the township...?

Seems like these (generics) were notoriously inaccurate. Anyone compare against a known standard such as lab results?

Since you were calling the twp, assuming it's the public water supply, not a well. If so, twp will have a water quality analysis. If a well, OTOH, twp official can tell you where to have samples analyzed.

Either way, first step is to know what you're treating. Next consider flow required -- how many in household. Most likely install a water softener sized to fit. Use TDS to calculate setting, per instructions. If no "special" contaminants, such as iron, sulfur, nitrates, bacteria and radon, (hope that's the case) you're done.

So you are buying another off brand tds meter to verify the validity of your first off brand meter?

[ ] Makes sense

The next step would be to buy a reverse osmosis system

PPM is a scale for everything that is dissolved in the water, good or bad. As Q2N said. Get a report from the water department (often available online) that will tell you what is in the water.

For most people on a city water supply, there are three components to whole house water filtration.
1. A whole house carbon tank. Removes chlorine and a host of other organic chemicals.
2. A whole house water softener
3. A point of use Reverse Osmosis unit. Usually installed under the kitchen sink to feed fridge and a separate filtered water faucet at your kitchen sink.

There is a slew of other information to consider before doing anything based on...

water quality.
where you get your water from.
General hardness test amount.
Pressure of supply water.
Pipe size of main water supply.
How many people live in household.

I use a TDS meter to check the effective of the RO membrane in my Reverse Osmosis water filter system. Does anyone know if I'm still getting 90%+ TDS removal from the RO membrane, do I need to change it out based on age of the RO membrane alone? I change the pre- and post-filters every 6months to 1 year.

Test your raw water ( the water coming out of a faucet anywhere in the house) and then your RO water. Divide the RO water into the raw water and you'll get a percentage.

Raw water =500ppm
RO water =15ppm

15÷500= .03

.03 is a percentage, 3%
100% minus 3% = 97% rejection level.

A proper working quality membrane is around 98-96% effective.

on average membranes last from 2-5 years.
