I filled the fresh water tank on my TT to flush all the lines. I am having trouble getting the pump to prime up. I made sure the bypass and valves are lined up on the water heater. Opened up all faucets and still nothing. I then tried to air out the system by using the city water hook up still could not get it to prime up. I think i found where the pump is but can't figure out how to open the door maybe y'all might have some ideas. I thought about just unscrewing the hinges to get the door off.
Also I found that they did not hook up the LPG hose to the outside kitchen tried to reach behind it to find hose but could not find it. Any ideas where it might be?
