Is there a hole or a crack? A hole will be easier to fix than a crack. If there’s a crack you might need to order a new valve from the air mattress manufacturer.This is a long-shot method and may not always work. Often, a severely damaged valve means that you’ll need to buy a new mattress.
, If the valve is leaking air because the valve plug isn’t properly sealing against the valve stem, you can line the stem with a thin piece of plastic to help it seal properly., If the valve is damaged beyond repair, order a new one from the manufacturer and replace it according to the instructions.
Assess the damage.
Plug the hole by filling it with rubber cement or seam sealer.
Seal the valve.
Replace the valve.
