I have a 50YDS049NCD311 that has been installed for about 6-years. Recently I noticed water inside of the unit and I think that it is just condensation. I plan to remove the top and investigate further this weekend. Does anyone know what size insultube that is needed for the internal piping? I will get foam tape too, but want to use the split type insultube where ever possible.
Insulation could be many different sizes between refrigerant and water piping. Before you insulate see if you can dry it out first. Then make sure you haven't developed a leak. The insulation can mask the source of the moisture.
