How Water Affects Your Dish Machine Results

Hello Water Lovers,

Every state, county, and city have different water conditions. Where they get their water from and how often the water source is replenished plays a big factor into water quality.

When it comes to a restaurant, a dish machine will quickly tell you how good your water quality is. Glasses and utensils will show spotting if water contains hard water.

What's hard water?

Hard water is water that has high mineral content. Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates.

How is hard water measured?

Hard water is water that contains dissolved hardness minerals above 1 GPG. Water hardness usually is measured or reported in grains per gallon, but some laboratories use milligrams per liter, or parts per million. ... For example if your water test shows 250mg/l hardness you actually have 14.62 grains per gallon.

Hard water Scale?

Degree of Hardness Grains per Gallon (gpg) ppm (or mg/L)
 Soft <1.0 <17.0
Slightly Hard  1.0-3.5 17.1-60
Moderately Hard 3.5-7.0 60-120
Hard 7.0-10.5 120-180
Very Hard >10.5 >180


How do you handle hard water?

The easiest and most cost effective way is to use a high quality rinse like the Power Dri, offered through the Chemical Xchange. Depending on your water conditions, you'll use 1 ml per rack for soft water conditions or 3 mls per rack for hard water conditions. You'll most likely need to use a delimer to maintain the interior of your dish machine, which we also offer! Only the best! 

Second options is to install a water softener.

The heart of a water softener is a mineral tank. ... Water softeners have a separate brine tank that uses common salt to create this brine solution. In normal operation, hard water moves into the mineral tank and the calcium and magnesium ions move to the beads, replacing sodium ions. The sodium ions go into the water.

Water Softener due consume a lot of water. During the recharging cycle it dumps a lot of water down a drain.

Of course using a water softener and a high quality rinse, you'll receive the best results.


Customers will perceive spotted glasses as dirty glasses. So make sure you pick up the best rinse in the industry.

Until next time.
