WATER SOFTENER

A water softener will improve the condition of your hair and skin, but there’s a practical argument for the investment, too: Reducing the amount of calcium, iron or magnesium in your water can extend the lives of your water-using appliances.

Water is considered hard if it contains more than 1 grain per gallon (GPG) of calcium, iron or magnesium. Indianapolis water typically ranges from 12 to 20 GPG, according to Citizens Water.
Hard water leaves mineral deposits behind when it flows, leaving stains near drains, spots on dishes, film on shower glass, scale on tubs and your clothes looking dingy. It will clog and shorten the lives of dishwashers, washers, water heaters, faucets and toilets, according to a 2010 Battelle Memorial Institute study that was commissioned by the Water Quality Research Foundation.

The study found gas water heaters using hard water lost half their efficiency over a 15-year lifetime, whereas those using softened water retained their original efficiency rating.

Showerheads using hard water lost 75 percent of their flow rate in less than 18 months, while those on softened water maintained a full flow.

Water conditioning companies will usually offer free analysis of your water.

About 70 percent of U.S. homes have hard water, according to the U.S. Geological Survey Office.

 

To explain why water softeners are beneficial and how they work, one needs to understand the differences between hard and soft water. It is presumed in this document that the water you are using meets all health regulations and is known to be safe.
What is Hard Water?
Hard water contains large amounts of calcium and magnesium — two minerals that cause the soapy scum on glasses and lime residue on bathroom fixtures. While suitable for drinking and gardening, hard water can cause mineral build-up in water heaters, pipes, dishwashers and showerheads, reducing its flow. Soap and shampoo’s ability to lather is reduced, and laundry becomes stiffer and duller in appearance.
As Table 1 shows, water hardness is measured with five different classifications and can be expressed in mg/litre or parts per million (ppm) or grains per gallon (gpg).
Table 1 Water hardness classifications
SOFT below 17 mg/litre or ppm (0 1 gpg)
SLIGHTLY HARD 17.1 – 60 mg/litre or ppm (1.1 – 3.5 gpg)
MODERATELY HARD 61 – 120 mg/litre or ppm (3.6 – 7 gpg)
HARD 121 – 180 mg/litre or ppm (7.1 – 10.5 gpg)
VERY HARD over 180 mg/litre or ppm (ovetr 10.5 gpg)

How to Decide if You Should Buy a Water Softener
Above 121 mg/litre, you may want to consider a water softener. Generally speaking, groundwater (well water taken from aquifers in the ground) is hard. Some municipalities in Canada use groundwater to supply water to residents. Residents, in small or rural communities, may not have municipal water service and get water from private or communal wells.
The most crucial step in deciding whether your home should have a water softener is to find out if your water is hard. If you have municipal water, call your water department or utility. If you have a well, contact a water-softening company that can conduct a test and classify its hardness.
How Does a Water Softener Work?
A water softener uses a medium that serves to exchange “ions” of calcium and magnesium with sodium and potassium.
This occurs in four steps:
1. To do the ion replacement, the water in the house runs through a resin bed of small plastic beads or zeolite. The beads are covered with sodium or potassium ions. As the water flows past the ions, they swap places with the calcium and magnesium ions. Eventually, the beads contain nothing but calcium and magnesium, and softening stops. It is then time to regenerate the beads or zeolite.
2. To regenerate, the beads need to regain their sodium or potassium ions by being flooded with a salty, brine solution that is rich in sodium or potassium.
3. Once completed, the calcium and magnesium, dirt and sediments are flushed from the beads and into the drain in a process called backwash.
4. The final phase rinses the mineral tank with fresh water and loads the brine tank so it’s ready for the next cycle.
Automatic water softeners are usually programmed to recharge at specific times that will not disrupt the occupants. It is more water-efficient to have a metered model that will regenerate only when required.
What are The Benefits of a Water Softener?
A water softener reduces water hardness, making it easier to shower and clean fabrics and dishes. With softened water, less soap is needed for bathing and laundry. Skin feels cleaner and clothing softer. Pipes, fixtures and appliances have less scale build-up. With less build-up, appliances can operate efficiently. Mineral-derived odours may be reduced; and, there are fewer deposit stains on bathroom fixtures.
What are The Different Kinds of Water Softeners?
Water softeners come in four different types — offsite, manual, semi-automatic and automatic.
Offsite — the portable exchange unit does not regenerate at your home, a company replaces the cylinder.
Manual — requires manual operation to perform backwashing, brining and rinsing.
Semi-automatic — all functions are controlled automatically, with the exception of regeneration.
Automatic — all functions are performed automatically, including regeneration.
This last type of softener can be controlled by the following systems:
Time-clock — regenerates on a pre-set schedule.
Water meter — regenerates based on volume of water; has two units so one can recharge while other is operating.
Hardness sensor — monitors the hardness of the water and activates regeneration when necessary via a sensor. This system is most costly to buy but will use less water and salt.
Where to Buy a Water Softener
Water softeners are sold by water equipment dealers, department and hardware stores. Units should be certified to the appropriate standards as outlined in the Certification section.

Where do I Install a Water Softener?
Water softeners are installed where the water line enters the home. A professional installer should carry out the installation. A separate cold line will be required for drinking and cooking purposes if you prefer to not consume softened water.
What Does a Softener Look Like?
There are two basic types of water softeners. There is a single upright cabinet style and an upright twin-tank style. Both are approximately 1.5 m in height and about .5 m in width.
How do I Maintain My Water Softener?
While most softeners need little care and will last for many years — problems may occasionally occur.
To ensure smooth functioning, the water softener should regenerate at least once a week to assure its longevity. If your softener is not working properly, there are several things to watch for.
• Check for salt build-up in the brine tank. If a crust has formed, remove it using a vacuum, clean with soap and water, and rinse well.
• If your water contains iron, check for iron deposits in the resin bed. If it is present, use an iron-removing product to clean the softener.
• Check the resin tank injector. If it is plugged with “dirty” salt, shut off the softener’s bypass plug, run a manual regeneration and then clean the injector and injector screen.
Consider machines that have controls that minimize water use during regeneration. Often, one cycling a week will be sufficient for a family of four.
Concerns About Water Softeners
Is softened water safe to drink?
A water softener cannot remove microbiological contaminants that cause illness and should only be used to treat drinking water that is considered to be microbiologically safe.
Water softeners replace “hard” minerals with “soft” minerals such as sodium. The fact that sodium chloride (a salt) is used to soften water raises a concern about the potential health risks for those persons suffering from hypertension, kidney disease or congestive heart failure.
As the incidence of hypertension increases and the number of individuals on sodium-restricted diets rises, water softener manufacturing companies have begun to promote the use of potassium chloride as a safe alternative to sodium chloride. However, potential health risks are also a concern where potassium chloride (also a salt) is used to soften water. Water containing high levels of sodium or potassium should not be used for drinking, making coffee, juice, infant formula or for cooking.
If you do not want this additional sodium or potassium in your diet, or if you are on a medically prescribed diet use a Reverse Osmosis system for consumption.

RainSoft is the only water company with a lifetime warranty on all parts. This is a 59 year old international company who will do the job right.
