So I made the horrible mistake of letting my early 90's 1200psi Alkota PW freeze this winter and now the vertical heating coil has more then one leak.. Could I get some pointers for the pros on where to start this project? Where to seperate the coils (I assume hacksaw for cleanest cut)?.. I have a plain jane mig welder running gasless fluxcore, will this work for the sch.80 piping I presume I have? It seems that you guys test the welds with air and I know it doesnt take much psi to test, would holding 10 psi work? Thanks for any help.. Rich
