How hard is Mesa's water?

The City of Mesa reports hardness typically between 12 and 22 grains per gallon depending on which source is serving the area. Anything above about 7 grains per gallon is generally considered hard. What Mesa hard water means explains the numbers.

Should a business soften all of its water?

Not always. Softening the hot water supply and the equipment that heats or chills water often gives most of the benefit. Drinking water and some outdoor uses may be better left unsoftened or treated differently.

Does a restaurant ice machine need its own filter?

Most ice machine manufacturers recommend filtration on the supply, and in hard water a scale-control filter or softened supply can extend the time between descaling. Follow the manufacturer's requirements for your model.

What is the difference between a softener and a filter?

A softener removes hardness minerals through ion exchange. A filter removes particles, chlorine or other contaminants depending on its media. Many businesses need both, for different reasons. Water softener vs filter sets out the choice.

In one sentence

Commercial water treatment is softening, filtration or reverse osmosis sized for a business's flow and equipment, installed to reduce scale, sediment or taste problems before the water reaches the appliances that depend on it.

What hard water costs a business

The scale bill arrives as equipment, not as water

Hardness does not shut a building down. It shortens the life of every appliance that heats or chills water, and it does it quietly until a part fails. In a commercial building the fixture count multiplies the effect.

12-22

grains per gallon

Typical hardness of City of Mesa water, depending on which source is serving the area.

Source: City of Mesa, water quality information

Ice machines
Scale coats the evaporator plate, slows harvest and triggers more frequent descaling.
Coffee and espresso
Scale builds in boilers and lines, and it changes how the drink tastes.
Dishwashers
Spotting on glassware, scaled heating elements and wash arms that clog.
Water heaters
Sediment settles on the tank floor and insulates the burner from the water it is heating.
Flush valves and aerators
Restricted flow and valves that stick open or run on, multiplied by every restroom.
Cooling and humidification
Evaporative equipment and misters scale over fastest of all.

Reading the building

Patterns that point somewhere

One fixture misbehaving is a fixture. The same complaint arriving from several places, or on a schedule, is the building telling you where to look, and it is the most useful thing to describe on the call.

Ice machines need descaling more often than the manual says

What it points to: Hard water is coating the evaporator. Softening or scale-control filtration on the ice machine supply addresses the cause.

Glassware comes out of the dishwasher spotted

What it points to: Minerals left behind as the rinse water dries. Softer water rinses clean with less chemical.

Flush valves and sensor faucets fail across the building

What it points to: Scale on diaphragms, seats and solenoids. The fixture count multiplies the repair bill.

Customers or staff comment on taste or odor

What it points to: Chlorine or dissolved solids rather than hardness. Carbon filtration or reverse osmosis at the point of use is the usual answer.

What is in these buildings

The equipment and materials, and what decides between them

Twin-tank alternating softeners

One tank serves while the other regenerates, so a business that runs all day never draws hard water during a regeneration.

Sediment and carbon filtration

Sediment filters protect valves and equipment; carbon reduces chlorine taste and odor for beverage and ice.

Point-of-use reverse osmosis

Purified water for drinking, coffee or equipment that calls for it, sized for that one use rather than the whole building.

When it is stopping the business

Start with what it is doing to the business, then the equipment involved. Open 24 hours a day, 7 days a week; timing gets settled on the call.

The sequence

How a commercial visit runs

Step 1
Measure the water and the use
Hardness, flow rate and daily volume decide the size of a softener, and a softener that is too small runs out mid-shift.
Step 2
Decide what to treat
Whole building, a hot water loop, or specific equipment. Not every line needs softening, and drinking water may need different treatment.
Step 3
Install with a bypass
Every system goes in with a bypass so water keeps flowing during service or regeneration problems.
Step 4
Plan the upkeep
Salt, filter changes and resin life set on a schedule matched to the site's use.

Worth knowing before you call

The details behind the scope

Hard water does not shut a business down. It shortens the life of every appliance that heats or chills water, slowly enough that the cost hides in repair invoices and descaling chemicals. JB Water & Air has treated water in the Valley since 1981, and the licensed entity's legal name, J B Sales & Water Distillers LLC, still reflects where the company started.

Mesa's water, multiplied by the fixture count

The City of Mesa reports hardness typically between 12 and 22 grains per gallon depending on which source is serving the area. A household feels that as spots on glass and scale on a showerhead. A business feels it across every ice machine, coffee brewer, dishwasher, water heater and flush valve in the building, all scaling at once. Hard water stains in Mesa shows what the minerals leave behind.

The useful comparison is not the cost of a softener against nothing. It is the cost of treatment against the descaling, part replacements and early equipment failures it prevents, measured on your own repair log.

Treat what needs it

A commercial system does not have to treat every drop. Softening the hot water loop protects the water heaters and the fixtures that use hot water. A dedicated filter or softened line protects an ice machine or espresso machine. Drinking water may call for carbon filtration or reverse osmosis at the point of use instead. Deciding where the water goes first keeps the system the right size.

Sizing for a business that does not stop

A residential softener regenerates overnight, when nobody is using water. Many businesses do not have an overnight. Twin-tank alternating softeners keep one tank in service while the other regenerates, so the building never draws hard water mid-shift. Sizing comes from hardness, peak flow rate and daily volume, which is why the assessment starts with how the site actually uses water.

Equipment manufacturers set the rules

Ice machines, combi ovens, espresso machines and sterilizers often specify the water quality their warranty expects. Some call for filtration; some specify hardness limits; some call for purified water. Those requirements come first. The restaurants page and the dentist office page cover how this plays out in those two kinds of businesses.
