Why Get a Filtration System for Ottawa Water?

The Standing Committee on Environmental Protection, Water and Waste Management is an Ottawa committee that deals with water and waste management. According to them, Ottawa meets the standards that they’ve set for high-quality tap water.

Their standards are based on whether or not the amount of contaminants in the water is acceptable.

If you’re not comfortable relying on someone else’s opinion regarding how much contamination is acceptable or you’re concerned about the possibility of contamination after water treatment, you’ve come to the right place because John The Plumber is your local water filtration expert.

We offer a variety of equipment and installation services to increase the quality of your tap water and reduce you and your family’s exposure to contaminants like lead, chlorine, bacteria, fluoride, sulfur, pharmaceuticals, pesticides, herbicides, and more!

Water Filter Systems

Depending on your wants and needs, there are several water filtration options to choose from. Read below for a brief description of some popular water treatment systems in Ottawa.

Whole House Water Filters

A whole house water filter is a water filter that connects to your water main. This means that the water from any faucet in your entire home, whether it’s hot or cold, is filtered and clean.  We can install a whole-home water filtration system, or you can rent your filtration system from us.

Under Sink Water Filters

Under sink water filters are, you guessed it, water filters that are installed under the sink! These water filters generally filter out the cold water supply provided to the faucet above.

Reverse Osmosis Systems

Reverse Osmosis Systems are multi-stage water filters designed to extract and remove an extraordinary percentage of impurities from your local water system.

When you have an RO system installed, you can expect better tasting water, less impurities and toxins, and money savings if you would otherwise purchase bottled water.

If you want better water for you, your family, and your guests, this is a great addition to your home that requires little maintenance!

Water Softeners

Water softeners are plumbing devices designed to soften hard water by removing the calcium, magnesium, and other minerals from drinking water.

If your faucets have watermarks, you have lime and chalk buildup in your sinks and showers, your white clothes don’t look great, your coloured clothes fade fast, your water smells or tastes a little funky, your skin doesn’t feel good after a shower then you may need a water softener.

Water softeners can save you money in the long run, they can make your skin and hair feel and look and feel better, and save you a lot of time from cleaning.

We can install your water softening system, or you can rent your softener from us.

Home Water Filtration UV Water Purification

UV Water Purification

99.99% of bacteria and viruses don’t stand a chance against UV lights in a UV water purification unit.

Anyone concerned about biological contamination in their water system can benefit from the peace of mind provided when a UV water purifier is installed.

Water Testing

If you’re concerned about your water quality, hardness, or contamination, a water test may either confirm your worries or offer you the peace of mind you’ve been needing.

Our experts will arrive onsite, collect all the samples required, and have them processed and tested to see what’s in your water supply.

It’s important to note that this test takes some time, and the results may not be available for a few weeks.

Water Filtration FAQ’s

Are there real benefits to drinking filtered water?

To be fair, we are extremely lucky to have the stellar quality of public water that we have.

However, no system is completely perfect, and while some of the treatments used in the water are considered acceptable, your idea of acceptable water quality may differ from that of the governing bodies.

Whether or not you will benefit from a filter filtration system is for you to decide. However, we imagine that less chlorine, sediment, fluoride, toxins, pharmaceuticals, pesticides, and other questionable possibilities can’t hurt!

Besides, whether or not your water is perfect right now, which isn’t possible, that doesn’t mean that you’ll forever be safe from public water contamination emergencies.

Tap Water From The Ottawa River

Ottawa’s water is considered soft, which means there are few parts per million of dissolved solids in the water. That’s good!

However, the Ottawa webpage that discusses Ottawa water admits that some strange odours in the water are due to trace levels of organic substances in the water source that aren’t completely filtered out.

The reality is that not everything can be completely filtered out. Additionally, chemicals are added to the water to prevent the growth of organic matter that would be unhealthy for us to drink. But, what is unhealthy for one lifeform is often not very healthy for us. And, while it is in a low enough dosage that the city’s Medical Officer of Health is satisfied, too much of anything must add up eventually.

All this to say, while we’re extremely lucky to have an abundance of acceptably healthy water, why not improve it if we can?

What Water Treatment Chemicals Are Used In Ottawa?

Some of the chemicals used for water treatment in Ottawa include Aluminum sulphate, Sulphuric acid, Sodium silicate, Sodium hypochlorite, Hydrofluorsicic acid, Sodium bisulphite, Sodium hydroxide, Aqueous ammonia, etc.

What substances can be found in Ottawa public tap water?

Some substances that could be found in Ottawa tap water include chlorine, fluoride, turbidity, barium, boron, chromium, sodium, nitrate, haloacetic acids, trihalomethanes, chloramine, etc.

To be fair, the results of many water tests are deemed acceptable by The Medical Officer of Health and Ottawa Public Health.

Do I Need A Home Water Filter?

If you’re asking whether or not you can live off the Ottawa water supply without a water filter, then yes. You can drink Ottawa water and you won’t die tomorrow of poison.

However, we are what we put into our bodies. New molecules are often being found in the human body that science didn’t previously know about. For example, microplastics were found in human blood for the first time in March 2022.

We’re constantly learning about the consequences of what we consume. Today, the health committee says that our drinking water is acceptable. But, tomorrow it might have a different opinion.

At the end of the day, with modern water filtration available at the prices they’re available for, I would recommend the upgrade if this is something that you’re concerned about.

Most of the plumbers at John The Plumber use home water filtration so they can enjoy great tasting water, clean water, less contaminants, and less worries about the future consequences of chemical consumption today.

How Often Should I Change My Water Filter?

How often you need to change your water filter depends on the water filter model, how much water you drink, and how clean the water is to begin with.

RO filters should ideally be replaced every year or more to ensure that it remains successful at cleaning your water.

However, if you notice that your water is beginning to seem a little off, listen to your gut! But, also make sure that you replace your filter at least as often as your instruction manual advises!
