Just a quickie if someone can answer....
Inside my DI vessel I have the cone shaped fitting at the bottom of the riser tube and the tube just goes to the top of the vessel where the in and out ports are. I have just checked my friend's vessel and he has a cone shaped fitting at the top of the riser tube as well as the base. Am I missing a piece at the top and if so is it needed?
If anyone could give me a quick explanation of how a DI vessel actually works that would be great.
