I got it figured how to vent the fresh water tank.
Not sure how to vent the gray water on the truck. In a house there is a cesspool vent when the line reaches the house. Then the drain pipe has a vent to the roof.
Will there just being a vent on the gray tank be enough? The tanks are only going to be 5' from the sinks.
Told my son that there has to be traps from the sinks to keep air/smell rising up the drain from the holding tank.
Is there anything I am leaving out?
Thank you to all that have helped.
Well you're lucky to have this Forum with folks that freely give explanation and help.
Your waste tank will need a vent to the outside of any structure you put on the truck's frame. Typically, they consist of a 1 1/2" ABS or PVC pipe attached to a tank fitting or through a tank grommet and led though the roof. This allows for venting of any gas to the outside at the top of the structure where winds bear it away.
Installing air admittance valves on any sink drains would be a good idea. When in transport, the traps can be emptied by the sloshing of water in the traps, leading to bad odors inside.
