Im about to have my pump overhauled. I have had 2 guys look at it and say the impeller is in super bad shape and looks like it has sucked up and punched out some big rocks. 1 guy quoted me complete overhaul and blueprinting of the pump/impeller. Another guy qutoed me at just replacing the impeller and all that goes along with replacing it.
my question is, what happens when my pump is blueprinted? is that somthing that i should do?? is a normal rebuild of a pump/impeller also called "blueprinted"?? please help!! i dont want to pay for somthing i dont need and on the other hand if its a good thing to have its only costing me 300 more than the guy that didnt mention "blueprinting".
