Hi, I have had my S-17 for about 6 months and I must say I am delighted with it. That's is until it started leaking about a month ago. Liquid is leaking from the top of the battery where it screws into the bottom of the tank. There is an air adjustment .screw in between the two. I have stripped it down and cleaned but it has made no difference. Jacvapour have kindly agreed to have a look at it for me but health issues make it very difficult for me to walk very far so posting it proves awkward. Are there any particular things I can do to the S-17 that may stop the leak. Thanks jack
