I'd like to replace me oil burner lines, the ones that run from the tanks to the burners. Anyone know if I can use regular 1/2" copper? It looks like the original lines are copper with copper or brass fittings. They leak like crazy at all the fittings, so I'd like to just put in a nice new run of 1/2" copper (about 30'), then have it break out to the boiler burner and the water heater burner in the normal 1/4" flexible tubing. I figure the filters would be better off in rigid pipe than the flexi tubing anyway. Anyone know if this is ok? Will oil eat through the solder or the solder pollute the oil or anything batty like that? There's seems to be no info about this on the web that I can find.
