Anything can be repaired if you know how and have the money. To fix a leak you first have to find out exactly where the water leaks from by looking and following the water trail. Once you know what is leaking then you can either replace the part, tighten the clamp or do whatever is needed. Without knowing exactly where the leak is coming from then nobody here can tell you exactly how to fix it.
