Check valve is not a good idea because the overflow line works in both ways.
1-air out: while filling-and water out if it is full and you still try to fill it up > you need it only if you fill up with your city water hook up
Also the water will expand if you fill it in cold and then stay in the sun for a while > tank will blow up
2-air in: if you suck water out with your pump, and if the water cools down if the tempereatur drops down
Of course you can ignore point 1 but then you have to open the inside filler cap while hook up the city water. If you forget this only one time you damage the tank and have a lot of water in your van
