In cold water factory AC systems that often occur leakage in the pipe connection, this causes the circulated water to be reduced and will have an impact on the AC to be not cold and even excessive. An easy way to find leaks is by connecting the parts of the connection pipe on the air conditioner by pouring soap foam on the part of the connection between the pipes, if the pipe joints come out the bubble is where there is a leak. After finding out the parts of the leaked pipe must be immediately patched with copper weld on the leaked part, it is agreed to be checked again by filling the freon and full of manifold needles whether the needle is moving or fixed, if the needle remains unavailable.
