In this video I had a problem with my water pump in my rv. I filled up the water tank to go dry camping. I had to first sanitize my water holding tank I used bleach to do it. After I had filled up the tank I I turned on the water pump. I could hear the water pump pumping or at least it sounded like it was. I waited for a few minutes to fill up the lines. I then turned on a spigot and absolutely no water or air was coming out. I then had to find my water pump and diagnosis how and why it wasn't pumping. After I took off the lines and found the problem the plunger was stuck it all was better we had water. No telling how much the jayco dealer would have charged me to fix it.
