I have 2 bathrooms in my house in which I installed identical elger brand toilets. In one I have a 4" cast iron drain line in the other I have a retrofitted 3" ABS flange that goes about 2-3' to the main 4" cast iron line. The 4" line seems to flush WAY better than does the 3" ABS line. Is this common? Should I pull the whole bugger out and reinstall a 4" line? Seems kinda silly to get a low flush toilet that I need to flush 2-3 times to get all the doo doo to go away. What say you all?
