FAQ
Aquasana FAQs
1. Does conditioned water feel slimy?
Because Aquasana’s Salt-Free Water Conditioner for Tankless Water Heaters does not replace hard minerals with salt, your water will not feel slimy or slippery as it would with salt-based softeners.
Since most licensed plumbers carry insurance to cover any damages caused by an installation error, having a licensed plumber install the system will give you the security that the work was done properly and peace of mind in knowing that the installation is backed up by the plumbing company's insurance plan.
The conditioner is designed to handle hardness levels below 25 GPG and works best with hardness levels at 15 GPG or below.
The Salt-Free Water Conditioner for Tankless Water Heaters is designed to last up to 2 years. The filter should be changed every 2 years for optimal performance.
The Salt-Free Water Conditioner for Tankless Water Heaters is designed to prevent the harmful effects of scale buildup in internal pipes and plumbing. Our system uses Scale Control Media (SCM) to alter the charge of hard mineral ions, so they do not bind together to create scale buildup. Unlike salt-based softeners, our Salt-Free Water Conditioner for Tankless Water Heaters does not need to remove the hard minerals from your water in order to reduce buildup.
No. Our system uses Scale Control Media (SCM) to alter the charge of hard mineral ions, so they do not bind together to create scale buildup. Unlike salt-based softeners, our Salt-Free Water Conditioner for Tankless Water Heaters does not need to remove the hard minerals from your water in order to reduce scale. Because hard minerals are not replaced by salt or other chemicals, TDS levels will remain the same even though scale formation is inhibited.
Yes. The Salt-Free Water Conditioner for Tankless Water Heaters is designed to protect the internal pipes and plumbing in your home from harmful scale buildup. Unlike salt-based softeners that replace minerals like calcium with salt, the Salt-Free Water Conditioner for Tankless Water Heaters instead uses Scale Control Media (SCM) to alter the charge of hard minerals, so they do not bind to one another to create scale. Because the Salt-Free Water Conditioner for Tankless Water Heaters alters the charge of hard minerals to inhibit scale formation and does not replace them with salt or chemicals, hard minerals remain in your water and will pass safely through your pipes and down the drain. If the calcium levels in your water are high enough, harmless calcium spots can still occur on areas where water is left sitting and can evaporate, leaving hard mineral deposits behind on surfaces like glassware, countertops, pots, pans, chrome faucets or stainless steel.
When dissolved minerals in water clump together, they form hard water. This hard water can eventually damage your pipes, plumbing, and appliances such as your washer and dishwasher. Hard water contains a higher-than-average amount of dissolved minerals (primarily calcium and magnesium), and a higher concentration of multivalent cations (Ca2+ and Mg2+).
No, hard water is not contaminated. If you have hard water, it’s more of a nuisance, but not harmful. Most water sources in the USA are considered hard.
Hard water can be city water or well water meaning it may or may not be pre-treated. The minerals that make water "hard" are not considered contaminants, but hard water can still contain additional contaminants that are not safe for consumption.
Soft water is water that has a lower concentration of dissolved minerals. If you’re unsure if your home has soft water, look for a healthy lather when washing clothes, dishes, and even your hands and body. If your home has hard water, the water will lather less because of the higher levels of minerals.
Soft water does not mean clean water. Your water can be soft and still have harmful contaminants present in the water.
Soft water is considered potable. However, drinking water from a sodium-based softener increases your daily intake of sodium, which can lead to health problems in sodium-sensitive individuals. Please keep in mind that a water softener is not a water filter. A water softener does not remove contaminants present in your water.
