Well I never had an issue with my cheap ebay/Amazon fill Station its the one that has the orange oring at the end. I recently got 2 more tanks and have ben using it a little more and it failed. Looking into it I have seen others say that its a known thing and I can either replace thay part with the item linked but I am curious if I should just invest in a better fill Station entirely. Thank you in advance.
