So borrowed an Eco safe groover from a friend. No carnage with the groover to speak of...Yah! As I was cleaning it I noticed the small rubber pressure relief gasket on the top of the 6" screwtop lid was getting old and it broke while I was cleaning the lid. So I have been looking online for either a replacement gasket or a lid and can't seem to find one anywhere yet! HELP! Just trying to make this right for my buddy but buying a whole new spare tank seems excessive.
