^^^^ this all you need is a lil soapy water in the area and it will tell you if you have a leak or not. If it bubbles up, you have a leak! If it doesnt - well you dont! pretty simple. Although if you do have a leak, it is in a pretty easily repairable spot. Depending on where you bought them, you can take it to be repaired. OR you can stick a plug into it yourself and call it a day...
