Quite honestly Tim at this moment my brain hurts and I am not 100% sure but I dont think it does. I am not at home at the moment and out most of the day tomorrow so I cant re check right now.

I have double checked the lines and the connections and there is no leak that I can see. I guess I will check that again tomorrow afternoon when it will have been standing for a while and if there is a slight leak it should show up then??
