Water Softener Size

The most important part of choosing a water softener for your home or building is to match the proper size to the property’s hard water removal needs. In order to do this accurately, it helps to discuss hard water management with a licensed, Indianapolis master plumber who specializes in soft water services. Otherwise, you will need to teach yourself how to calculate the proper size water softener.

Water softener capacity is measured in “grain removal” and in the United States, the average gallon of water has 10 grains of hardness in it. To calculate how much “grains” your establishment uses, you need to know that the average person uses around 80 gallons of water each day. You can get a more detailed explanation of estimating water softener capacity by reading, “How to Calculate Water Softener Size.”

The basic formula is as follows:

(Gallons Per Day x Number of Occupants) x Grains Per Gallon = Total Grains Used Each Day

Single-Tank Water Softening System

A single tank water softener system consists of a single cabinet that holds both the brine tank and the resin tank. This compact design allows it to fit into small spaces, making them perfect for apartments and single-family homes. These water softeners are also referred to as, “on-demand” systems, which monitors your water consumption by the gallon. Once capacity is achieved, the system will regenerate during off-times, such as the middle of the night or early morning. This process provides soft water at all times. For properties with fewer than five occupants, single-tank systems are an efficient choice.

Twin-Tank Water Softening System

A twin-tank water softener system is better suited for properties with more occupants. It consists of two resin tanks, rather than just one found in single-tank systems, as well as a brine tank. One resin tank provides soft water all day long, while the other tank regenerates. Although the duel-tank design takes up more floor space, it is an efficient choice for large families. They are generally more expensive than single-tank systems since they are larger and come with a backup tank.
