not long after buying ours new, all the while fighting symptoms of air in the pump/lines, I had a small flood in the kitchen area near my pump location. Turns out that the strainer cap on mine was cracked Looked to have been put on just a bit too tight.
The MH was new (although it had been on the dealer lot for a long time) and I'd never touched that thing so it was either the factory, the dealer, or I suppose a freeze might have done it but unless it was during manufacture and delivery I'd say that's doubtful. It does freeze where the dealer is pretty far down in Florida, but not long and not often....so my bet is someone over tightened the cap.
I had the same experience....once I was able to get in touch with thor, they sent me a new cap out lickety split
