NO NSF Logo
Class A Customs Fresh and Gray Water Tanks do not have the NSF logo molded into them due to changes NSF made regarding the use of the NSF logo. Class A Customs for several years was allowed to use the NSF Logo in our Fresh/Gray water tanks because the materials all the tanks are made from including the fittings are NSF Certified Materials.

The NSF Company does not allow for end users to use the NSF logo unless each item has been inspected and a certification paid for, the material that all of our tanks are made from are still the same NSF Certified Material that was used when we were using the NSF Logo in our water tanks, adding this extra step of certification is an unnecessary step but generates revenues.

The NSF Company does not allow vendors/manufacturers to link to the NSF paperwork unless verified NSF products are being used, Class A Customs has been verified and is allowed to link to the NSF Certified Materials page located on the NSF website. If needed your inspector can check on this regarding our company and website as we have already provided this information to the NSF company and have been advised on how to correctly use/link to the certification information on our website. Health inspectors would need to contact NSF directly to verify this.


Before you build or modify unit verify rules and regulations.
Codes vary by local health departments, not state.
We are not aware of the codes or rules. We are not aware of what tanks or items you need.

Forward the documents and tank information provided to your local health department before purchasing to be sure these tanks will pass your local inspection, this is your responsibility.




My health department doesn't care, they won't look... my builders said it is ok... I am just updating tanks.
We hear this and then get the call needing a different tank sent overnight to meet a deadline. It takes very little time to check before and saves you time and money. Forward the documents and tank information provided to your local health department before purchasing to be sure these tanks will pass your local inspection, this is your responsibility.


What does my inspector need when I go to inspections on the tanks?
Print the Water Tank List (Ctrl +P or Command- P will bring up the print window)
NSF Paperwork (Ctrl +P or Command- P will bring up the print window)
Receipt of Purchase
All tanks have the part number molded into the tank, inspector can verify tank.

Will the tank material handle ___________ chemical?
Fresh/Gray Water Tanks & fittings made from DOW NSF International NSF/ANSI Std 61 approved Medium Density Polyethylene (MDPE) Resin and are to be used for Fresh or Gray Water only. We are not aware if the tanks can withstand placing other chemicals onto the tank such as spray foams, paints, adhesives. You would need to verify this information.
