Q: what fittings do I need to order to use in a conversion van as a water source?
It is recommended to use plastic NPT male fittings with plastic female NPT fittings to avoid damaging the threads, metal thread fittings can crush the plastic threads. Very little, if any, pipe thread tape is needed using too much pipe tape will damage the threads. We do not recommend pipe dope as you can not remove the fitting later, if used be sure to use a food safe brand. Do not over-tighten fittings as damage will occur.

Sanitize each tank prior to use to remove any debris from the manufacturing process
Non-Pressurized Tank all tanks we carry must be vented allowing air in and out when in use, Plumbing Examples
Do Not hook a garden hose directly to tank damage will occur, it is recommended to use a fill dish or other gravity process
Do Not over-tighten fittings as damage will occur.
Very little, if any, pipe thread tape is needed using too much pipe tape will damage the threads. We do not recommend pipe dope as you can not remove the fitting later, if used be sure to use a food safe brand.
Tank can be placed on any side.
Place tank on level surface and brace to prevent tank from moving during transit.
Tank needs to be adequately supported, examples on the Water Tank Helps Page
Do Not hang by ratchet straps, this is too thin and will not adequately support tank.
Do Not place weight on tank, if you need to stack the tanks you will need a weight bearing shelf between them.
Tanks can be installed inside or outside of unit, for food vendors verify requirements before purchasing as some areas do not allow tanks to be outside of the unit and others do not allow the tank to be inside of the unit.
Be sure to Sanitize Tank before installing.
All tanks must be braced and secured to prevent any movement of the tank while in transit and to prevent possibility of tank tipping or falling.
Due to the manufacturing process all the tanks especially the larger in size will have a bowing to the walls, when the tank is filled the tank will expand out removing the inward bow, we recommend laying all tanks on a level surface (this can be angled to help with drainage) and bracing the tanks. For larger tanks it is recommended to brace all side walls with plywood or metal, we do not recommend using ratchet straps on the tanks alone as this is a large amount of weight on a thin strip and may cause cutting into the tank. For tanks placed outside it is also recommend to enclose tanks using sheet metal / plywood or some other type of weather proof material to prevent damage from road debris and speed bumps, be sure to check your clearance before ordering.
Brackets or Strap Systems Due to the variety of installations we do not carry brackets or bracing systems.
Codes vary by local health departments, not state.

Water Tank Percent Calculation Examples
Multiply (fresh tank size) x 1.15 (1 . 15%) = Tank needed
30 x 1.15 (15%) = 34.50
30 x 1.50 (50%) = 4
NO NSF Logo
Tanks no longer have the NSF logo molded into them due to changes NSF made regarding the use of the NSF logo. 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 each item, the material that all of our tanks are made from are still the same NSF Certified Material, 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, our company has been verified and therefore is allowed to link to the NSF Certified Materials 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.
