You need to examine all the hold areas really well and be sure it isn't coming from a drain line or other water line area there. Then you can take the belly pan loose and look under there if you are sure that is where it is coming from. You don't have to destroy anything. It comes off. You can usually just take a portion loose and look in there with a flashlight and see where it is coming from. Lines are pretty durable. More likely a tank leaking. Hope that helps some. Please get back to me if we need to dig deeper into this as all follow ups are included in our fee.
Just checking back in to see if you got this resolved or do you still need more assistance from me here?
