7/11 Importance of an Air Gap

In the realm of water softener systems, an air gap is an absolute necessity for safeguarding the purity and safety of your water. Its absence leaves room for the intrusion of backflow contamination , putting the cleanliness of your water at risk. An air gap acts as a shield, separating the water in your softener system from the wastewater in the sewer line.

This division ensures that there is no cross-contamination, guaranteeing the cleanliness and purity of the water you use for various purposes such as cooking, cleaning, and drinking. Lacking an air gap opens the door for contaminants to seep back into your water supply, potentially jeopardizing your health and causing damage to your plumbing system. To keep your water softener system efficient and long-lasting, it is crucial to ensure that it is equipped with an air gap.

Never underestimate the significance of this seemingly small component. Its role in preventing backflow contamination and preserving the quality of your water is indispensable. Safeguard the cleanliness, safety, and purity of your water by making sure your water softener system includes this essential feature.
