Yes, I would fix it myself.
Home plumbing and electrical are pretty simple disciplines, as far as repair goes.
Initial installation and meeting all of the constantly changing codes is a different matter.
But as long as the installation was proper to begin with, troubleshooting and repair is pretty simple for anyone with an IQ above ambient temperature. Just remember, water and electricity follow the path of least resistance. And remember to turn off either at the source before getting into the conduit, because you do not want either of them leaking out where they do not belong.
