How do you inspect a removable waterproof backpack liner?
Identify the liner specified for your exact backpack, inspect it separately if the maker allows removal, and check that it is reinstalled correctly. A clean outer shell alone does not establish the condition of the waterproof compartment.

Some motorcycle backpacks use a separate internal liner as part of their protected storage system. Others use a different construction. Find the product documentation before assuming that any loose inner fabric is a removable waterproof part. Note the exact model and version, particularly for a second-hand bag.
Kriega’s R22 description identifies a removable taped-seam white liner attached with hook-and-loop strips. Kriega also describes the roll-top Drypack closure as part of its waterproof approach. Those details make the attachment, liner and closure relevant inspection points for that system. Kriega R22 construction, Kriega Drypack explanation

Our visual checklist is to empty the compartment, photograph the attachment arrangement, and remove the liner only as documented. In good light, look for debris, obvious punctures, separated seam tape or damage around attachment areas. Note exactly where a problem appears rather than treating all discoloration as a leak.
Check the top opening and the parts involved in closing it. Look for an object, folded accessory or displaced attachment that could prevent the prescribed closure. Do not fill the backpack with water to prove that it is waterproof unless the manufacturer specifically directs such a test; that is a different use from storing belongings in the intended conditions.
Choose cleaning, refitting or replacement deliberately
If the liner only needs cleaning, use its maker’s care directions and complete the required drying before refitting. If the issue is damaged material or seam tape, ask about a compatible replacement or approved repair rather than assuming a wash will restore the barrier. Keep photographs of the damage and the bag label for support.
Match a replacement to the exact backpack model and generation, then follow its installation instructions. Check the attachment all the way around and ensure that the liner lies as intended before adding belongings. Repack without trapping its edge in a closure or removable accessory. If unexplained moisture returns, record the conditions, where it first appeared and whether the reservoir or another carried liquid could be the source. A visual inspection can find obvious defects and installation mistakes; it cannot certify waterproof performance or identify every possible route for water entry.
