From the factory, my drinking water system leaked from the fixture under the sink that leads to the fridge in the slide. After stupidly waiting too long after I knew something was wrong because the pump was cycling, I had water everywhere. Sounds like Jayco needs some training for whoever is installing these lines. Not complaining too much, overall that has been the biggest problem I've had so far.
Also, my pump is 120V as well. Which is think is pretty shortsighted, but my guess is that there is no other 12V in the island, so they took the easy way which is to tap into the 120V. I don't camp much without power, but I do some. And it doesn't run off the inverter either.
