This dawing is for a library of 2D plumbing blocks showing various drainage fittings with couplings. It covers side elevations of Y-branches, elbows, tees, and reducers in standard metric sizes ranging from 50 to 150. I’ve also included symbols for cleanouts and floor drains. These could be useful in residential or industrial waste water system layouts.
