Plumbing question

[FstEddie1411]

I have a dish master imperial four M76 in my 1999 Windsport. I want to put cut off valves on the hot and cold water under my sink. I called Thor with my Vin# and they told me they can’t even pull up that vin cause it’s so old . I just need some one to tell me what the water line is it’s not 1/2 dis on the inside it’s smaller I know this is very elementary question but I haven’t owned an RV before. The repair shop where I live is not a place I’d like to do business.
Thx
Eddie

The smaller water lines are 3/8" and 1/4". These are INSIDE dimensions. I.E a 1/2" PEX pipe is 0.625 inches. If it is 3/8" PEX the outside dia will be 1/2" and that is probably what you have if it is PEX. My 1968 coach has 3/8' copper lines for hot and 1/2' garden hose for the cold water, so you never know?
