NSF Approved Water Storage Tanks: What does this mean?
The letters NSF stands for the National Sanitation Foundation. Among other things, this organization sets the standards for potable water storage and handling systems. To achieve NSF certification, a company must pass the following steps:
- Annual verification of the chemical formulation of each water contact material in the product.
- Annual on-site inspections of the manufacturer's production facility to verify the materials and production process for each Certified product.
- Annual testing of samples of the complete finished product, to ensure products meet the stringent requirements of NSF Standard 61 and do not leach dangerous levels of contaminants into drinking water.
*NSF certification can also be granted by UL, or Underwriters Laboratories.
How do I figure out if my water tanks are NSF approved water storage tanks?
Now you may be wondering, how do I figure out if my water storage tank is approved by UL and NSF. Generally, the tanks will have the UL or NSF sticker on them. If not, you can find certification details on the UL database or the NSF database. Every company and product that is certified will be on one of these sites. It is important to make sure that any water storage tank you buy is UL or NSF approved.
This way, you can be sure you are buying a quality product that has been tested and proven to be safe for use with potable water.
