Frequently Asked Question

Reverse osmosis (RO) is a filtration process that reduces impurities from household water. The process forces water through a specialized semi-permeable membrane that catches mineral, chemical and bacterial impurities making the water cleaner for drinking, cooking and general use.

Water filtration systems remove contaminants from the water. The contaminants removed depend on the type of filtration system installed. Some contaminants that could be removed from your water include arsenic, iron or copper along with industrial and pharmaceutical byproducts like hormones and pesticides. The removal of contaminants can also help alleviate foul odours in the water.

Water filtration systems cover a wide range of products such as reverse osmosis filtration, whole home chlorine filtration and iron filters which all work to help remove various contaminants and aesthetic concerns about your home’s water supply.

Hard water occurs naturally when water flowing in rivers, streams and even through underground channels comes in contact with the rock in the Earth’s crust. Hard water is not harmful to your health but can create mineral deposits in your plumbing, water heater and other water-using appliances, possibly shortening their lifespans.

Some of the benefits of an RO filter system could include:

    Longer-lasting appliances due to less scale build-up

    Fewer spots on dishes and glasses

    Longer life expectancy of fabrics and clothes

    Better feeling water when washing, and better lathering from soaps and detergents

Tap water can appear cloudy as a result of tiny bubbles from dissolved air being released once water flows from your tap. You’ll notice this more in the winter time as the water coming from the reservoir to your home is colder and holds air longer than warmer water. Cloudy water does not typically post a health concern but may look unappealing to some people.

Chlorine is added to tap water to kill germs and make the water safe for consumption. Although the amount of chlorine added is regulated it can impair odour and taste.

There are many factors to consider when choosing the correct filtration for your home. You have to determine what exactly your water problem is. It’s best to consult with a Water Purification Advisor to help find the right solution for you and your home.

Working water is used for bathing, laundry, toilets and cleaning. Ideally it should be free from chlorine, iron and hardness, which will have a big impact on water-using appliances, plumbing and cleaning.


Drinking water is safe for drinking and cooking. It needs the most amount of treatment to ensure it is safe for consumption.

Chlorine filter is often referred to as a carbon filter. Carbon is the filtration media used to remove chlorine from the water using a process called chemical adsorption.

Whether or not you need a water softener depends a lot on where you live. Certain regions have particularly high levels of hard water. Water hardness is measured by grains (of mineral) per gallon (GPG), or by parts per million of mineral (PPM). One GPG equals 17.1 PPM. Water with up to 3.5 GPG can still be considered soft for many homeowners. Water with more than 10.5 GPG is considered very hard.

If you notice any of the following, you may have a hard water problem:

    Soap scum on your hands and hair, sinks, bathtubs and shower doors

    Scale build-up on plumbing fixtures and pipes, water heater, dishwasher, humidifier, coffeemaker and other water-consuming appliances

    Spots on silverware, glassware and mirrors

    Soaps, shampoos and detergents that don’t lather the way they should

    Bright colour fabrics get dulled quickly

     There are also other effects of hard water that you may not notice immediately, such as shortened lifespans of water-consuming appliances like dishwashers.

There are at least 4 reasons to get a water softener:

    You live in what is considered a hard water area

    You could reduce the amount of soap needed to create a lather

    You could maintain plumbing fixture appearance and function

    You could enjoy the feel of softened water when washing and taking a shower

The water softener passes the hard water through resin beads which have soft sodium or potassium ions attached. When the water comes in contact with these beads, an ion exchange takes place with mineral ions in hard water – essentially the two sets of ions trade places!

Water softeners are not water purifiers, so they do not affect the quality of your water. Only certain minerals that cause water to be hard are removed during the water softening process.

Newer models like our advanced water softener systems, use far less salt than most people think. The estimate is about one large bag of water softener salt per adult, per year.

Although salt is used to soften water, you won’t necessarily have salty-tasting water. Many people with water softeners drink and cook with softened water without noticing any difference in taste to distilled water. However, if you prefer the taste and texture of distilled water, you could consider adding a drinking water treatment unit to your water softener. A Home Comfort Advisor can help you choose the right one for your needs.

By renting with us, you never have to worry about your water softener’s lifespan or potential breakdowns. That’s because we will service and replace the unit (if necessary) for no extra charge.

Surprisingly, no! Simply keep one or two bags of salt in the salt tank and always keep it plugged in. Newer models have self-charging capacitors, so in the case of a power failure the memory and program will remain intact. You should never clean out your salt tank, as this may introduce air into your system which, although easy to fix, is just a make work project. Let the salt level go down, and all the water and salt will exchange, keeping your tank clean in the process.

Our number one service call is related to salt, not to the softener itself. Keep your salt level below the halfway mark to avoid what’s called ‘bridging’. Check your salt level every three months or so. If the salt in the tank becomes a solid block, it will not dissolve and so it cannot recharge your water softener resin.

Do you have a private well with iron issues? Your water softener may take out trace iron, but an iron filter will do a much better job. It will also protect your water softener from damage caused by iron in the resin bed. It’s easy to test the level of iron in your water with a small water sample.

Typically, your water softener will use three to four square feet, but we offer two different models: compact cabinet and dual cabinet. The dual cabinet allows for more versatility in setup as it requires a smaller footprint.
