Ford Transit 16-Gallon Undercarriage Water Tank w/ Stainless Brackets (TR-UC-16) Installation Instructions:
This is a quick installation of the tank with it mounted in the most forward position. You may choose to mount it in a slightly different position and adjustments to bolt locations will need to be made. Here is a picture for reference of the undercarriage looking rearward from the front of the van.
- Cut 4 bolts flush to body hanging into the cavity where the tank will sit. These are underneath the pinch weld of the body as shown in the picture.
- Bend muffler shroud towards muffler rounded down towards ground. This will allow better access to bolt locations and protect the water tank from the exhaust system.
- Remove front exhaust bolt for muffler hanger. There should be a side bolt as shown in the picture that will not be removed. This bolt will be used to support the front tank bracket
- (2) Hexagonal holes are to be enlarged with step bit to fit the Rivnut.
- Holding the tank in place with a helper place the bracket onto the tank at these (3) mounting positions (For our tank location the straps were roughly 13.5”, 26” and 35.5” from front of tank) on the frame and mark each hole to be drilled out and Rivnut installed.
- Once all the Rivnuts are installed the tank can be mounted with the brackets and hardware supplied. Tighten all bolts once in place.
- Your tank is now ready for plumbing.
How to Clean Our Camper Van Water Tanks:
Make sure you rinse the water tank before first use, as there can be plastic bits left in the tank from the manufacturing process.
Nomadic Supply Company recommends using our Lippert Floë Compressed Air Camper Van Fresh Water Flushing System throughout the year to keep your water system completely pristine. In addition to flushing your water system you can also use bleach or vinegar to clean our fresh water tanks, or you can one of our camper van fresh water tank cleaning solutions. To clean your tank with bleach or vinegar follow the instructions below.
Step 1: Drain the water tank completely
Step 2: Mix 4 oz bleach or vinegar with 1 1⁄2 gallons of hot water
Step 3: Pour bleach/vinegar solution into tank
Step 4: Fill tank with fresh water until its full
Step 5: Let sit for 12 hours
Step 6: Drain the water tank completely, refill with fresh water and drain completely again (you may need to repeat this rinse step a few times)
Camper Van Water Tank Venting:
Polyethylene camper van water tanks must be vented. These fresh water tanks are not designed to handle pressure or a vacuum. A vent is necessary because as the tank is filled or emptied of its liquid an equal proportion of air must be displaced simultaneously. Discharge of a water tank without a vent would cause a vacuum to occur. A generally accepted rule concerning vent size is that it should be the same size as the tank’s largest outlet.
