getting water to the tap.

[nostalgic]

Thanks id never even thought of that one. I did notice though there seems to be a gromit like thing about a foot after the water tank just as the pipe turns to go up through the vans floor, dont know what that is, allso thinking about it i never thought to make sure when filling the tank that the water was staying inside it, what a mistake that would be ( and you can all stop shaking your heads and tutting now.)

The grommet type thing may be a non return valve

That's a great idea about checking to see if the water is actually staying in the tank. . If it is try disconnecting one section of pipe at a time from the tank and blow through it back towards the tank , if you can't you've got a blockage ( then make an appointment at your doctors ). Daz
