We have been leaving in our trailer since Nov. 29th.
I had four leaks. The first one at the inlet for the city water was found before I picked up my TT. The dealer repaired it.
The second was at the outlet of my water pump. I could not get it tight enough and another RVer suggested that I use teflon tape and that fixed it.
The third one was at the input for the Black water tank flush. It was barely put together. I took it completely apart. I had to remove the plate on the side of the trailer. After tightening it up and putting it back together it is now OK.
The third leak was at the T that splits the water from the pump to the hot water heater and the cold water feed to the rest of the trailer. It is one of those small Ts that are crimped in. Fortunately when it is cut out of the system a pressure fit T is the right size to replace the crimped T. I purchased the pressure T from Camping World and now I have no leaks for the last month.
