How Do You Determine Water Softener Size?
To determine the appropriate water softener size for your home, multiply the number of people in your home by the gallons of water they use each day (80 gallons per person is the average). Multiply that number by the grains of hardness in your water to figure out how many grains need to be removed each day.

Moreover, what size water softener do I need for a family of 4?

Determine the proper water softener based on your hardness and number of people in your house.

Number of people in your house
Hardness in Grains Per Gallon 1 to 2 people* 3 to 4 people*
5-10 GPG 32,000 Grain 32,000 Grain
11-20 GPG 32,000 Grain 32,000 Grain
21-30 GPG 32,000 Grain 40,000 Grain

can your water softener be too big? If your water softener is too big for your home, it won't do enough work to trigger regeneration on time. When a water softener doesn't regenerate, it's not as effective and bacteria can grow in the tank. There are a lot of ways to make sure your water softener is properly sized for your home.

Also to know, what does the grain number mean in water softener?

Grains per gallon is the industry-standard way to discuss water hardness. Diving mg/L by 17.1 will convert it to GPG. A "grain" of water hardness is equivalent to 1/7000th of a pound. It is very important to know your water hardness when you're considering the purchase of a softener.

How do you determine the grain of hardness?

If a test for hard water is measured in parts per million or milligrams per liter you can take the total hardness level and divide it by 17.1 to get hardness in grains per gallon. For example if your water test shows 250 mg/L hardness you actually have 14.62 grains per gallon.

Is water from a softener safe to drink?

However, there has been no official verdict to state that drinking softened water is a problem and softened water is considered safe to drink. Most water softeners work by removing the minerals present in hard water, such as magnesium and calcium, through a process known as ion-exchange.

How much salt do I put in my water softener?

The amount of salt you should add to your softener will vary by the level of hardness in your water and the amount of water your family consumes. The average family of four with hard water, or levels around 7-10 grains per gallon hardness, will typically use about 10 lbs. of salt each week.
