I'd contact GP and tell them about it, then if they send you a new one COOL. If not I'd consider fixing it my self. By the way if GP says they will send a new one, make sure you don't have to send the old one back and go ahead and fix it.
I fix my own stuff but I'm not going to try to tell ya how to fix yours. I do know that the first thing I would do if fixing it would be to drill a small stop gap hole at the end of the run then work from there. Good Luck ! ENJOY !!! RED
