What Size Of Water Softener Do I Need and How to Size It?

Soap scum, dry skin, brittle hair, and stubborn bathtub rings are annoying and common signs of hard water in your pipes. If you’re dealing with these issues daily, it may be time to consider a properly sized water softener to solve them for good.

In Toronto and its surrounding regions, the average water hardness is around 117 mg/L. At this level, you may start noticing scale buildup on fixtures and appliances, which can gradually affect their efficiency. These issues also compromise your comfort and quality of life, which is why a water softener can be the best solution.

Installing the right water softener system begins with understanding water softener sizing and choosing the right water softener for your needs. At Water Mart, we have customized water treatment solutions designed to enhance your water quality and prevent skin, scalp, and hair issues. We also offer advanced systems that are energy-efficient and self-cleaning, designed to control the calcium and magnesium levels in your water.

Let’s have a look at the following guide for more clarity about the size of water softener:

Household Size and Water Usage

The first step in measuring the size of a water softener is to determine the overall household size and water usage.

In general, an average person consumes around 60 to 70 gallons of water a day. If you multiply this figure by your household size, you get an estimate of your daily water usage. Furthermore, checking your water bill provides a more accurate estimate of overall water usage.

Determining the Hardness of Your Water

The only factor that decides how big a system you need is the water hardness level. The higher the hardness, the more advanced the system to effectively remove the minerals from your water supply.

Water hardness is measured in Grains Per Gallon (GPG). The higher GPG indicates more dissolved minerals, such as Calcium, Magnesium, lead, etc. You can find your water hardness level by accessing the annual water quality report. However, there are more reliable options to determine the water hardness.

How to Measure Your Water Hardness Level?

Besides checking out your annual water quality report, there are two other ways to measure your water hardness level.

Professional water testing for accurate measurement, which is 100% FREE, is one of the most reliable ways to measure water hardness. The results we provide are not mere figures, but also a comprehensive guide to water softening systems as per the GPG, ppm, or mg/L level for your hard water.

The other common option includes getting a home test kit from online stores or local hardware stores to check the water hardness level.

What Does Grain Capacity Mean?

Grain capacity is the unit to measure the total amount of minerals in the water. For instance, one grain is equal to 1/7000th of a pound.

Thus, a water softener should have a 32,000-grain capacity to remove 32,000 grains of hardness from the water, and so on.

Ion exchange softeners must be recharged through a regeneration cycle, especially when the resin beads in the appliance become fully saturated with hardness grains.

The regeneration process allows the resin beads to be rinsed with a salt solution to clean the softener’s bed for efficient working.

Note: You need a higher grain capacity if you have high water hardness levels.

Do All Water Softeners Use Salt?

No. Salt softeners come in two major categories. However, if you have moderately hard/hard/extremely hard water, only salt softeners would help you get rid of the mineral content.

Salt-Based Water Softeners

This is the most common and effective method to remove high mineral content from your water. Salt-based water softeners use an ion exchange method with a resin bed filled with sodium ions.

The hard water is allowed to flow through the resin bed where sodium ions take the place of the mineral content, such as Calcium and Magnesium, and sweep them out during a regeneration cycle.

Salt-Free Water Softeners (Water Conditioners)

The salt-free water softeners do not actually remove the hardness. Instead, they change the physical properties of minerals.

Salt-free water softeners are not effective for very hard water like that of Toronto. Moreover, they are low maintenance with low initial cost as compared to salt-based water conditioners.

Pro Tip: If you’re based in Toronto, Canada, or in places with very hard water, a salt-based softener is the way to go.

What are the Benefits of Using Efficient Water Softeners?

Investing in a water softener is the best investment you could ever make, especially in areas where water hardness is high.

However, some water softeners in the market do a below-average job and add to your expenses. At WaterMart Toronto brings we provide the best, most cost-effective, and energy-efficient water softening systems your home would love!

Here are a few benefits of using efficient water softeners in your home.

Efficient salt-based water softeners use less salt during the regeneration cycle, saving you money.
They contribute to lower water bills and reduce environmental damage by using less water during the regeneration cycles.
Cost-effective, energy-efficient water softeners are self-cleaning and ensure hassle-free maintenance and increased peace of mind.
Efficient water softeners use less intense regeneration processes, improving the lifespan of your appliance.

How Much Water Does Your Softener Need To Handle?

Once the water hardness levels in your area are confirmed, it’s time to make an informed decision about how much water your softener needs to handle.

Mainly, it comes down to two main points:

Water Hardness: The higher the water hardness, the more water your softener needs to handle.

Daily Water Consumption: The higher the daily consumption of water, the more water your softeners need overall.

To measure the amount of water your softener needs to handle a week, we use a simple formula:
Daily Water Usage (gallons) x Water Hardness (GPG) x 7 (days in a week) = Total Grains Required
Here’s how you calculate the perfect amount of water your softener needs to handle.

Pro Tip: Always add 25% more to the result for unexpected water usage spikes.

The Impact of Flow Rate

Accessing the flow rates in your household is also crucial before choosing the ideal water softener for your home. Usually, the number of people in a household equals the amount of water consumption.

For example, if you have two people in your home, the flow rate would be less as compared to when there are around 6 or 7 people living in a household.

Therefore, if your water softener cannot handle the flow, it would cause errors and would be inefficient in treating hardness for the entire household.

Thus, the flow also affects the amount of water your softener needs to handle.

Consequences of Improperly Sizing Your Water Softener

Imagine installing a highly efficient, cost-effective, and self-cleaning water system only to find it doesn’t work as it should. How heartbreaking!

However, the issue doesn’t even lie with your water softener but with your sizing estimates. If you’re improperly sizing your water softener, it won’t have the capacity to remove hardness from your water, resulting in scale buildup, soap, scum, and other problems.

Above all, an undersized softener requires increased maintenance services to compensate for its limited capacity. Therefore, it is important to properly size your water softener before making a final decision.

Is an Oversized Water Softener Bad?

An oversized water softener is not as problematic as an undersized one; even so, it’s not recommended.

To cater to your water hardness problems, an oversized water softener does the job well. However, it doesn’t help much as far as efficiency is concerned.

Here are a few problems associated with an oversized water softener:

Large water softening systems use more salt per regeneration cycle, resulting in an increased cost over time.
An oversized softener uses more water per cycle to flush out the hard minerals, contributing to a higher water bill.
Large-capacity softener units have higher initial costs.
Therefore, using a water softener of an ideal size is essential to keeping your environment and costs at bay.
