Stainless steel commercial tanks are considered the best among all because stainless steel is a sturdy raw material. It is corrosion-free and it does not cause pollution or contamination into the water. Just like PVC or plastic PVC which have been discovered to be causing chemical lynching in the water and that’s why PVC and plastic tanks are rejected by health-conscious households, even if they are cheaper than stainless steel water tanks. Business establishments are not ready to use PVC or plastic water tanks, because of the way they contaminate the water.
