1.375" hose can not be used with spouts on tanks
Q: I purchased a 40- and 46-gallon set from you. Is this kit everything I need to set up a fresh and gray water tank as far as getting water into the tank and vented safely (beside the fill dish)? Can I get the line that goes from the fill dish to to the fresh tank in 10 foot? Same with the vent hose? And all of these are food grade, correct?
Due to the variety of set-ups we do not have an all-in-one system.
We carry a number of items in our Plumbing Category but you will need to verify they are the items you will be needing, have a certified technician install all parts to prevent product damage and personal injury.
Q: Is this tank baffled?
Class A Customs only installs the following fittings into our Fresh / Gray tanks at this time
1.5" NPT Female - fitting is closed
.5" NPT Female - fitting is open
1.25" Outer Diameter x 2" Long Smooth Pipe / Boss Fitting - Spout
use a razor knife to cut membrane out, easiest when cut in halves
1.375" hose can be used with the fill dishes and the Loose Fitting / Fixture - 1.5" Thread x 1.25" Hose Barb Fitting - Gray
1.375" hose can not be used with spouts on tanks.
glues does not stick to pipe, it can not be sealed or capped
you will need to use the 1.25" Hose with Clamp
1.25 hose hose can be used with the gravity dishes and spouts/boss fittings on tanks.
1.25 hose does not fit the Loose Fitting / Fixture - 1.5" Thread x 1.25" Hose Barb Fitting - Gray
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.

A garden hose (a connection from your faucet indoors, etc. anything that pushes the water) is a pressurized water line, do not make a secured connection to the water tank with a pressurized line. Tanks need to be gravity feed, this allows for air to escape while the water is going into the tank. You ca use a Gravity Fill Dish located on the outside of your vehicle to fill the tank, please view the Basic Plumbing Diagram below.
"Venting" the tank lets air move in and out of the tank when in use. Tank must have a large enough opening for air to freely move in and out of tank, if tank is not properly vented tank will explode when filled or implode when emptied. Trying to use a pressurized line "half-way" to prevent damage to the tank will does not work because you can control the amount of water flowing but not the pressure in the line, leaving the tank to fill risks exploding the tank or damaging fittings.
Sanitize each tank prior to use to remove any debris from the manufacturing process. Tanks are made in a warehouse, wipe with a damp cloth to remove surface dust or scuffs
For my application I am not using a fill dish.
can place a larger fitting such as a PVC elbow into the per-installed
tank fitting and just rest the garden hose / pressurized line in this
fitting, Do not make a
secured/sealed connection as this would then be pressurized and would
damage the tank. This would then be a gravity fed fill, you can make the
same type of fitting set-up for your vent.
- Be sure to
have an additional fitting open at the top of the tank to let air in/out
when using the tank, this would be your vent.
- You can cap the fitting (a) and vent (b) when transporting to prevent water from spilling.
- Be sure to uncap the vent when removing or adding water to the tank.
- It is best to have a screen over the vent fitting to prevent anything from entering the tank.
UNISEAL FITTINGS INFORMATION
Uniseal® Pipe-to-Tank Seals
Uniseal® is the world's best seal, and installing it is a simple process. After cutting a hole in the wall of a tank or other surfaces, the seal is inserted. Then the pipe is coated with a slippery detergent and pushed into the seal. The Du Pont Alcryn® is the key to the liquid-tight seal. When the pipe is pushed through the rubber-like Uniseal® from the outside, the inside Alcryn® wall becomes thin enough to allow the pipe to squeeze through and then forms a liquid-tight seal. The coefficient of friction with the plastic pipe is roughly three times higher than any other material, which allows it to create a better seal than with any other material.
- Alcryn® melt-processable rubber
- Resistant to acids, oils, greases, gasoline & sewage
- Withstands pressure & suction
- Withstands heat & cold
- Easy installation
- Reduced labor & material costs
- In static conditions, the seal is good up to 65 psi
Instructions1. Be sure to have recommended hole saw for selected fitting, check chart before cutting.
2. Using hole saw cut hole in wall, ensure that the hole is cut clean. Irregular holes could cause poor seating and possible leaks. File or sand the edges so there are no rough or sharp edges be sure to remove any remaining debris.
3. Insert the Uniseal with the wide surface facing out.
4. Make certain the pipe to be inserted is cut clean and square, file or sand the edges so there are no rough or sharp edges to cut the Uniseal surface.
5. Use liquid soap or Teflon lube on the pipe to be inserted. Insert the pipe into the Uniseal as far as needed to clear the inside of the seal by about 2".
Sch 40 Pipe I.D.
Pipe O.D. Size *2
Holesaw Size Required
*1 - Uniseals U025 and U0312, Uniseals U050 and U075, Uniseals U275 and U300, Uniseals U400 and U400-SDR35 require the same sizes of holes.
The difference is made up in the thickness of the Sarlink 4165 rubber.
*2 - Always measure the Outside Diameter (O.D.) of your pipe. This is the most important size to match into the Pipe O.D. hole size of the Uniseal to create your seal.
