How to Know The Right Size Of Water Softener For Your Family


Step 1: Figure Out Your Average Daily Water Use Per Person In Gallons.


According to Watersoftenerfacts.ca http://watersoftenerfacts.ca/softener-buyers-guide/ the average person in the Waterloo Region consumes about 195 litres (51.5 US gallons) of water per day. You can use this number in your calculation.




If you would like to be more accurate do the following. Take a look at either your fall or winter water bills. This will give you a better idea of your indoor water usage since during these months you are not using water outside. To calculate your household's average daily water use, divide your fall or winter water consumption (given in cubic metres) by the number of billing days for that billing period. You will find both of these amounts on your bill. Convert cubic metres to gallons by multiplying by 264.

Step 2: Multiply Your Average Daily Water Use By The Number Of People In Your Household


Take the number that you calculated in step 1 and multiply it by the number of people in your household.


Step 3: Determine Your Water Hardness Level


You can determine your actual water hardness level by looking at the maps of the Kitchener-Waterloo, Cambridge, and Guelph Regions provided here.  The following chart will also give you a rough idea of the water hardness level in your area. If you are using a private well you should get your water hardness and iron tested separately in order to get your hardness rating.

According to our sample family of 4 above using 5,200 grains per day, the recommended size of softener they should buy is one with a 40,000 grain capacity.

Why Is It Important To Choose The Right Size of Softener?


Choosing the right size water softener is important.  According to watersoftenerfacts.ca, http://watersoftenerfacts.ca/softener-buyers-guide/ it is estimated that "134,723 household water softeners use at least 2.7 billion litres of water and 44,700 tonnes of salt every year. To put that in perspective, it is equal to more than 10 Olympic-sized swimming pools and about one third of the weight of the CN Tower in salt!" The right sized softener will operate more efficiently, use less salt and less water, which is good for the environment and will help you save money.
