We have just purchased a 2008 Swift Charisma 555 to go on our seasonal pitch. Does anyone know the diameter of the drainage outlet. If our existing 10 meter drainage pipe doesnt fit we will need to purchase more. I think our existing pipe is 28 mm
You could measure the outside diameter of the pipe with a ruler or,take off the part where the pipe plugs into as it should be simple to do as, usually there is only 2 screws holding it on.
