How Our Water Testing Process Works

Water testing helps identify what is actually affecting your home’s water before choosing a treatment solution. Nelson Water provides water testing for Ottawa homeowners looking to better understand issues related to hardness, iron, sulfur, bacteria concerns, sediment, odours, staining, and overall water quality.

Step 1

Assess Your Water Concerns

We start by reviewing your water source, visible symptoms, and household concerns, such as hardness, staining, odours, sediment, cloudy water, or well water issues.

Step 2

Test and Interpret Results

Your water is tested for common quality issues such as hardness, iron, sulfur, pH, sediment, bacteria concerns, and overall water conditions. We explain the results clearly so you understand what is causing the problem.
Step 3

Recommend Solutions
for Better Water

Based on your results, we recommend the most appropriate solution, whether that means a water softener, filtration system, UV treatment, reverse osmosis, chemical injection, or a complete water treatment setup.

Why It’s Worth Having Your Water Tested

Water testing helps you understand what is actually in your water before choosing a treatment system. Instead of guessing based on taste, smell, or appearance, a water analysis gives you clear information about the issues affecting your home.


Many water problems are not visible. Hardness, iron, sulfur, bacteria, pH imbalance, sediment, tannins, nitrates, and other concerns can affect water quality, plumbing, appliances, and drinking water confidence.


Many homeowners in Ottawa and surrounding communities schedule water testing because it helps them:

01

Identify Hidden Water Issues

A water test can reveal concerns that may not be obvious from taste, smell, or appearance alone.

What Do Our
Customers Say?

We had a great experience with Nelson Water. Will Deeks came to install our water softener system, and he was very professional, friendly, and knowledgeable. He explained everything clearly and answered all of our questions with patience. He made sure the system was set up properly and that we understood how to use it. We are very happy with the service and would highly recommend Nelson Water to anyone looking for a water softener system.
Shadab M.Google Reviews
We only moved into our new home a couple of months ago and based on the previous owners notes they had been using Nelson Water and having them service both the water filter and pump for years. So, today I had a service technician come out for the annual preventative maintenance, and Frank could not have been more professional, knowledgeable, and friendly. He was more than happy to answer any of my questions since we've never had a well or a water softener in the past. Now, I have no problems recommending Frank and his company to all of my friends and family!
Mike R.Google Reviews
Josh came to repair our water softener and he was fantastic. He told us what needed to be replaced and showed us the broken part when he took it out. He was very professional, friendly and polite and he cleaned up the area where he worked. This was the first time we dealt with Nelson Water as the softener was in the house when we purchased it.


We highly recommend this company; our first experience will keep us coming back for sure. Well done Josh and thank you!

Kim WoodsGoogle Reviews
Joshua performed a service on our older (2001) GE water softener. It was a really positive experience. Joshua is very knowledgeable, explained all of the symptoms and indications we saw and gave us advice on salt that will help deal with our iron. The resin bed should be replaced, and he explained the pros and cons of repair versus replacement and provided written estimates of replacement systems.


Fantastic water system technician and really knows this technology. Nelson is an excellent dependable firm, have been with them 20 years, recommend them strongly.

What is a water analysis, and why do I need it?

A water analysis involves testing your home’s water to assess its quality and identify any contaminants or impurities present. It’s essential for understanding the condition of your water and ensuring the health and safety of your family. We also check for hardness, iron, sulfur, PH, TDS (total dissolved solids). We also do bacteria testing through our certified lab.
Free water analysis. However any testing done from our lab is provided at our cost.
Typically about 20-30 mins.

Yes, you can drop off a water sample at our office. When you arrive, our team at the front will take your information and pass on the sample to our water specialist if he is not present in the office. The specialist will call you back with detailed results and recommendations. Please ensure the sample is collected in a clean container and properly sealed to avoid contamination. 

Yes, you need to be present during the water analysis. This allows you to speak with our specialists directly, ask any questions you may have, and gain a better understanding of your water quality. Your involvement ensures that we can provide the most accurate and tailored recommendations for your specific water needs.
Essentially anyone can do a water test with the right testing material, however if you go with us it is free and you are provided with recommendations from our experts.

Not on its own. Public Health Ontario’s free test checks only for E. coli and total coliform bacteria; it does not test chemicals such as hardness, iron, sulphur or pH. Those are behind most staining, odour and appliance problems in rural wells. Our free in-home analysis covers hardness, iron, sulphur, pH and total dissolved solids, so the two tests complement each other. (Ontario.ca)

Test for bacteria at least three times a year, in spring, summer and fall, and test the chemistry every one to two years as a baseline. Test sooner after flooding, heavy rain or the spring melt, or whenever the taste, smell or colour changes. Our Ontario well water testing guide explains what each test covers.

An in-home analysis checks hardness, iron, sulphur, pH and total dissolved solids (TDS) on the spot, in about 20 to 30 minutes. Bacteria testing goes to a certified lab. The on-site results come with a plain-language recommendation, such as a water softener, iron filter or reverse osmosis system.

It isn’t needed for safety: city water is treated and monitored, and the central supply is very soft (about 30 mg/L hardness). Testing helps if you dislike the taste of chloramine, the disinfectant the City uses, or if your home was built before 1958. About 15% of Ottawa homes were originally built with lead service pipes. Homes on the City’s communal well systems get much harder water, 200 to 350 mg/L. (City of Ottawa)
