Your service technician will walk through your home, inspecting the plumbing system; tighten any loose handle or packing nut during the inspection process. All the emergency shut-off valves under the sinks, toilets, water heater and your main water shut-off, will be tested to insure they operate in case of an emergency. Gas connectors will be inspected visually as well as any exposed piping. You will be shown where the main shut-off valve for your water and gas piping are located.
