I had that issue after only two uses. Luckily my trailer was just barely still in warranty. I looked at a way to repair at home, as I do everything else around the house and am a professional HVAC mechanic, and didn't find a way to repair. I took it to the dealership and they ordered the part from Gulfstream. If it were to happen again, I would look into getting a tank from some place like State trailer, Amazon, or some other supplier. I want to add an additional tank and increase my freshwater capacity as my tank is under the bed and I have room. Just a tight space for my big belly. Hahaha. Good luck.
