Leaking valve
Also: valve leak
If a boat loses air at the valve, it's usually due to sand, a missing or cracked O-ring or worn threads.
Clean the valve, check the O-ring and replace it. Alpacka also describes leaks at the weld around the valve, which are sealed with Aquaseal. Spare valves for Anfibio and MRS are available in the Packrafting Store. Sand never belongs in the valve; according to the Packrafting Store it's a common cause of permanent leaks.
