PEX in Chicago: a gamble worth taking?
I’ve recently begun the renovation of a frame construction two-flat in Chicago. Its two separate apartments with a basement and an unfinished attic. I have researched PEX and would love to use it to replace all the rusting galvanized metal water supply lines. The main advantage for me is that a PEX manifold and homerun-style system would give both apartments equal water pressure during use ( ie. I don’t get a cold shower while my downstairs renter does the dishes) BUT Chicago apparently doesn’t allow PEX as a potable water supply line. It’s not illegal to install but it is not considered code approved. So my long winded question is, is it worth the risk and just installing PEX, with the hope that soon Chicago will allow it? Is there a way to design a copper pipe system that is (relatively) affordable and provides even pressure, efficient hot water wait times, and doesn’t waste material?
As PEX is generally accepted in all 50 states and other major cities., It’s a very frustrating day to be a Chicagoan.
Would love some advice. thanks,
