I just purchased a new WildWood LE 29BHSS travel trailer and am having trouble finding out what exactly this water heater by-pass looks like and where it is located. It was something recommended when purchased and my wife and I ordered it but now I'm having trouble locating it to make sure what we paid for is there. Both my wife and I are new to RVing and this is our first trailer so we are a bit un-educated with this. Any help or suggestions would be greatly appreciated! Thank you!
