With the expansion tool almost 1/5 the price of the crimper is there a downfall to using expansion fittings as opposed to the copper crimp rings? The whole theory behind expansion joints seem like such a good idea as the pex is going to be working to keep the fitting compressed, not working against it. Is there a downfall to using the expansion tool and using expansion fittings as opposed to other methods??
