How do I find and repair air leak in an inflatable boat, kayak or raft?
If you are losing air pressure, (aside from pressure loss commonly caused by colder temperatures), check the boat over for air leaks. Air must to escape somewhere for air chamber to become soft. No magic here. The best tool to find air leaks is soap, shampoo or dish detergent mixed with water in a spray bottle. Start by checking the valves first. Spray around the valve on a suspected air chamber. If you see bubbles forming, check your valve fitting and base and be sure the valve insert is screwed on tight and pushpin is in correct position. See FAQ below for more help with leaky air valves. To find tiny leaks on a boat surface, fully inflate the boat until it’s hard to the touch. Put some liquid detergent in a bucket of water and scrub it all over the boat with rag or big wash brush. Watch for elusive or tiny bubbles. When you find the first leak, keep looking. You might as well fix them all at the same time! Remember, the number one cause of slow leaks is due to poorly fitted valves.
