We took the new trailer for a quick trip to a State Park an hour away after a cleaning & check-out thrash. The temps got into the mid 20s so I had to put some water onboard and unhook the hose so it wouldn't freeze the pipe. I noticed the pump took a long time to build pressure and stop and wondered what was up. Back home and winterizing for the first time I found this. The tubing from the fresh water tank to the pump has a 90 degree kinked bend where it comes through the floor. You'd think the guy who sprayed the foam in the hole would have seen this. A 90 elbow will fix this before we go out again. Also discovered the black water gate valve doesn't work correctly, I suspect it isn't opening fully. I was reminded that camping/RVing is 2 hobbies.... camping and maintaining the RV.
