Step 1. Test the plumbing system for leaks. Test the drain, waste and vent systems and the water distribution system. The inspector neither performs nor provides the means for conducting the test of the plumbing system.
To test the drain, waste and vent system, make sure that all pipes and fittings are properly glued. Plug all openings tightly and look the system over carefully to make sure all is ready for the test. Fill the system with water to the roof (or at least 10-feet high for a groundwork) and check the entire system for leaks.
To test the water distribution system, make sure the system is completed and ready to hold pressure. Connect the system to the water source of the building so that the system will be tested with the water pressure that will exist in the system under normal operating conditions. Check the entire system for leaks.
The drain, waste and vent system and the water distribution system must be under test and not showing any sign of leakage at the time of inspection.
Step 2. The "groundwork" inspection. Plumbing systems installed below ground, such as under a concrete floor that needs to be poured before continuing construction, must be tested and inspected prior to cover. Call the inspection line to request a groundwork inspection. Do not cover any of the pipes before the inspector approves the work.
Step 3. The "rough-in" inspection. This will be an inspection of the entire plumbing system that will be concealed within the construction of the walls, floors or ceilings. Call the inspection request line to request a rough-in inspection. Again, the inspector needs to see all of the system, so do not cover any part of the system prior to inspection.
Note: This inspection must be completed and approved prior to contacting the building inspector for your framing inspection.
Step 4. The "final" inspection. When the fixtures are installed and operational, you must call the inspection request line and request a final inspection. Although the system will be operational, remember that the system is not approved for normal use until final approval.
Note: This inspection must be completed and approved prior to contacting the building inspector for your final building/occupancy inspection.
