When and why should I test my water?
If your business location or your water source has moved
Water quality can vary depending on your water source and other environmental factors. Even if your company’s new location has a water treatment system already, you should still test your water to ensure it's effective against any current issues.
If the water has smell, taste or odor issues
Water with a foul odor or taste could make eating and drinking anything but enjoyable. For example, iron is known to leave a metallic aftertaste, while chlorine can create an unpleasant bleach smell.
If there is buildup or residue
Common indicators of water problems include buildup on fixtures, increased maintenance costs and residue on appliances. If left unresolved, water issues can cause long-term damage to water-using equipment, which can be costly.
If production costs and/or utility bills have increased
Problem water can cause wear or scale on appliances and utility equipment, which leads to them running less efficiently and using more energy.
