YOUR BATHROOM PLUMBING DIAGRAM To Show What You Have in Mind
When you’re planning major bathroom renovations, a bathroom plumbing diagram, showing your existing plumbing lines and your planned changes, may be required by your local building code department, in order to get your plumbing permit. There are many plumbing jobs that can be done by homeowners, and a rough-in plumbing diagram of pipes, drains, vents and waste lines is a very good idea if you’re planning to make any major changes to anything.
Some parts of the country require a licensed plumber to make those major changes to plumbing, so be sure to check your local building department.
The plumbing projects that require permits are also subject to building code inspections, so make sure you know your limits if its a major plumbing job. A rough-in plumbing diagram is done so the plumbing inspector can make sure you are not making illegal connections, or inadequate slopes and angles prior to issuing the permit. Your drawing should show a “blueprint” of your plumbing so the inspector can establish that your system will meet the minimum standards of the building codes.
Remember; if you own your home, you are the general contractor. That means you can work on, hire subcontractors for and oversee most remodeling jobs in your home. Hopefully, plumbing will be among the list of things you are allowed do.
The other use of the bathroom plumbing diagram is to help you gather the building materials. While you're working on your bathroom plumbing diagram, write down the pipe diameters and lengths of all pipes. Count the connections and fittings you'll need to buy (get one or two extras of each).
When drawing your bathroom plumbing diagram, draw the diagram as you are facing the wall and start at the center of the wall, making diagonal pipes run at proper angles. A small triangle can be helpful and, as always, a pad of graph paper is near critical.
Do this for each wall where you plan to change or create your new plumbing. You’ll be expected to show how new plumbing will connect to existing supply lines, drains, vents or waste lines. There are symbols to indicate which fixtures (tub, sink, etc.) are being connected to each pipe. Your plumbing inspector may be able to provide a sheet or drawing of these or click plumbing schematic sheet here. Once you have received your plumbing permit, you’re ready to rock and roll! Take your time ... and happy plumbing!!
