Down the Drain(s)
Stefan's crew has been working all week on putting the master bathroom drain plumbing in. City code says you have to use cast iron below grade. Luckily the main drain pipe to the street is about 3 feet down below the gravel, so it was not difficult to create a system that flows down using good 'ol gravity. There are a couple tricks to putting in the custom shower drain (without curb) and the tub drain/p-trap learned from Stefan on Saturday morning. Those will be covered in detail after I get a photo. I must impart this infomation on others before they try to put drain plumbing under concrete!
