What Size Water Softener for Family of 3
So yous recollect you need a water softener for your abode, but are non sure where to starting time.
The start affair you should determine is the actual size of softener you need. A water softener that is too small volition frequently run out of soft water, reduce water pressure, crave more service, and take a reduced service life. Oddly enough, a water softener that is also large can endure from a unlike fix of problems.
5 Factors Yous Need to Know
- Flow Rates
- H2o Volume
- Water Quality
- System Chapters
- Regeneration Frequency
Flow Rate Requirements
Flow Rate Guide
How many places could your family unit use h2o simultaneously? Could you lot have ii sinks running, a toilet flush, and bathtub fill at the same time?
Flow rates are measured in gallons per minute (gpm). Information technology'southward crucial non to undersize your water softener when it comes to flow rates.
Tip: Add the maximum number of fixtures you could use at once (ii sinks + i toilet + i bathtub).
If your softener is too small-scale and you endeavour and apply too many fixtures simultaneously, y'all will feel a large drop in water force per unit area followed by difficult water and iron bleed through.
A well engineered organisation integrates the internal diameter of the bypass valve, control valve, mineral tank, distribution system, as well equally the volume and blazon of ion exchange softening resin. The combination of these components volition make up one's mind the flow charge per unit a water softener tin back up.
H2o Volume
How much full water does your family utilise throughout each twenty-four hours – a little, or a lot?
Average domestic water use is 75 gallons per mean solar day per person (75gpd/person). This means an average family of four would use 300 gallons per day. Heavy water utilize (lots of laundry, long showers, etc.) tin can hands add together upwardly to 100gpd/person or more.
Tip: Multiply the maximum number of people x your estimated use/person (4×100 = 400gpd)
H2o Quality
Water softeners can be used to remove dissolved calcium, magnesium, atomic number 26, and manganese.
Calcium and magnesium are measured in grains per gallon (gpg) while atomic number 26 and magnesium are measured in parts per 1000000 (ppm). When sizing a water softener, you must convert the measurement of all minerals into grains per gallon (gpg).
Tip: Multiply parts per million (ppm) of iron and manganese x4 to convert them into grains per gallon
Calculating Total water hardness
20gpg hardness
4gpg fe (1ppm x 4)
1gpg manganese (0.25ppm x 4)
= 25gpg total hardness
Tip: Information technology is far more than efficient and effective to use an iron filter to remove iron and manganese instead of a water softener.
Organisation Capacity
Water softeners are full of small-scale plastic beads called ion exchange resin. These resin chaplet remove hard water minerals past pulling them out of the h2o – much like a magnet.
A water softener'due south capacity is based on the corporeality of resin inside the unit. ane cubic foot of resin can remove 32,310 grains of hard water minerals (calcium, magnesium, fe, and manganese).
Tip: Mutual residential sizes include 0.75, i.0, 1.v, and 2.0 cubic foot systems
One time a system has reached chapters, the resin chaplet will be covered with minerals, and be incapable of softening the h2o. At this point the system will have to clean itself out with salt (too known as regeneration) to resume softening.
Tip 2: To make certain y'all don't run out of soft water betwixt regenerations, add 30% extra chapters for a reserve or safety factor.
Regeneration Frequency
Would your car require more than service if you lot collection 40,000 or ten,000 miles per year?
Softeners are no unlike. Mechanical components in a water softener only accept to work during the regeneration process. During service, h2o but flows through the system.
Metered water softeners measure the amount of water you utilize, and will effort and regenerate often enough to keep up with usage. An undersized softener will have to regenerate also often, and its mechanical components will work overtime. This excess load reduces the life of all mechanical components.
Tip: The ideal water softener size has enough capacity to las 4 days between regenerations.
Putting it all Together
Here is a common household in the Twin Cities with extremely hard water, lots of h2o apply, and a demanding flow charge per unit requirement:
Period Requirement
x gallons per minute (dishwasher + washing machine + 2 sinks)
Volume Requirement
400 gallons per day (4 people 10 100gpd/person)
Water Quality
25 grains per gallon (gpg) Total Hardness
The scary part (Math):
400 gallons 10 25 grains = 10,000 grains per 24-hour interval
10,000 grains x iv days = xl,000 grains required
Even scarier (Division!):
40,000 grains/0.7 = 57,412grains capacity required (we just added a 30% reserve)
This family would do best with either a 48,000 grain unit (ane.5 cubic anxiety), or ideally a 64,000 grain unit of measurement (2 cubic feet). Annihilation smaller would run out of chapters and work too hard to keep upwardly. Anything bigger would regenerate likewise infrequently and may crusade resin damage (peculiarly with iron – merely that'southward another commodity altogether).
Our Sample Recommendation
Our 64,000 grain ProMate 6 water softener would exist a great friction match for this family. The 13" diameter tank can deliver upwards to 18gpm and would not restrict h2o pressure. It also has enough capacity to operate comfortably and efficiently for a very long time.
With a little thoughtful planning, soft water can be very easy!
