The water pressure in all of my sinks and showers is close to nothing. It has been great for months. When we left our camp ground yesterday, I thought that if I opened the blue and red line underneath the belly, then I could slowly drain out some fresh water while we were driving. Since I did that, the water pressure has been very bad. It seems like those two lines were holding pressure or something. I also noticed that there was another blue line just by itself a few feet away from the two lines I opened. Maybe it was that line I should have opened? Does anyone know what I should do to get water pressure back? I own a Cyclone 4005 HD edition. Thank you!
