Inside diameter of water lines.

[Reboot123]

Would anyone know the inside diameter of the water lines in my Travel Trailer. I have a JayFlight 2015 33' RLDS. Some say the inside diameter is 1/2" and some people say the inside diameter is 3/8". Tsk in Advance for the replies.

PS = If the inside diameter is 1/2" then the outside diameter would be 5/8".
If the inside diameter is 3/8" then the outside diameter would be 1/2".

Here in Canada we have inside diameter 1/2" and outside Diameter 5/8". This is what is mostly used.

My 2016 has all 1/2" Pex water lines which are actually OD 0.625, the ID is 0.485

Id = 1/2", od = 5/8"

X-2 PEX is standard on all JAYCO units.
