Arlington has a fnew fitting, its a nm2520 http://www.aifittings.com/whnew108.htm All it is is a pvc male adapter, but it says you make your own pvc expansion couplings using a piece of 2 1/2" over a piece of 2" pvc. Is this a legal way to make a expansion joint? I always buy the made expansion coupling, but I could easily make my own.
