What types of inspections are required for plumbing installations?

When it comes to plumbing installations, several types of inspections are typically required to ensure compliance with safety standards and building codes. These inspections help to verify that the plumbing work meets local requirements set forth by authorities, such as the Washington Suburban Sanitary Commission. Initial inspections usually occur before the plumbing system is concealed. This means that there will be a rough-in inspection, which assesses the layout, materials, and placement of pipes, fixtures, and drainage systems before they are covered by walls or floors. This inspection checks for proper sizing, compatibility of materials, and overall adherence to plumbing codes. After the rough-in stage, a pressure test is often conducted. During this inspection, the plumbing system is filled with water or air to confirm that there are no leaks. This step is crucial for ensuring the integrity and safety of the plumbing system. A final inspection is also required once all the installations are complete. This entails a thorough examination of the entire plumbing system, including fixtures, valves, and connections. The inspector will ensure that everything is functioning properly and that the system is both safe and efficient. Homeowners and contractors are encouraged to be aware of these inspections and to schedule them accordingly.
