I bought this air pump about a year ago, it has worked great! But a while ago it would only work for the first few minutes of turning it on then the bubble pressure would go way down (hardly any bubbles at all). I took it apart and I noticed a slot in the black rubber (I don't know what to call it). I will post a picture and maybe someone can tell me if those slots are suppose to be there. Thanks!
