Do you ever think about how much water consumption you have in your operation? Dishmachines, ice machines, coffee brewers, kettles, steamers…they all require water for operation. And the quality of your water not only affects the product but it affects the efficiency of the equipment.
All water contains minerals that can make it hard. Calcium and magnesium are the main culprits. Lime scale deposits, formed by these two minerals can clog pipes, reducing flow and coat heating elements, requiring more energy to heat water. When our customers let us know that they have water issues, we will steer them toward a water filtration system. There’s several brands; Everpure, Watts, Ice-O-Matic, Hoshizaki just to name a few. Not only will a water filtration system reduce lime scale deposits, it will also filter out chemicals, like chlorine, minerals and small particles found in many water supplies with the potential to cause valve failure and plugged nozzles. By using a water filter system, particles, as well as chlorine, will be reduced and likely extend the life of your equipment.
But, just because you’ve got a system in place, doesn’t mean you’re finished. The system can only help you if you stay up with filter maintenance. The filter cartridges are designed to remove contaminants and particles from the water. The cartridges will eventually plug as this material is removed. When filters get plugged up, it means that they are working. In order for your filtration system to continue to working, the filters need to be replace periodically.
The frequency of changes depends upon your water quality and usage. For example, if you have a high level of particles in your water they you will have to change your filters more than a location with little or no particles. Here are a few guide lines for filter changes:
Prefilter – the prefilter (coarse) cartridge should be changed when it becomes dirty to within 1/8″ of the core.
Submicron Cartridges – cartridges should be changed at the first occurrence of any of the following:
- the gallon rating stated on the label
- every 12 months
- the pressure gauge needle of the filter system falls in the red zone while your equipment is calling for water.
A simple rule of thumb is to replace your filters whenever you notice a decline in the performance, whether it is a drop in flow rate and/or pressure or an unusual taste in the water.
