So I have been getting some good advice on the "ask the plumber" thread. It was suggested I start a "build" thread, which makes sense.
I started out by replacing my water main with new 1" copper (we dug the trench by hand). See thread below for where it all started, and where it may go wrong.....http://www.tacomaworld.com/forum/off...lumber-11.html
At this point the task is to install a new high efficiency direct vent water heater.
Though I do need to pour a few cubic feet of concrete first for the water heater to sit on. A structural engineer signed off on the design, which will entail epoxying rebar into the existing footing etc.
But before I commit to the water heaters final location location, I want to rough in the water heater so I'll no exactly where to pour the concrete.....
