I have a Mag 12, but I bet the Mag 5 is similar. All you have to do is
remove the impeller housing and impeller and clean them. Inspect the
impeller carefully for broken fins etc. Vinegar and water works well at
removing any calcium deposits. Just make sure that you rinse it very well
before hooking it back up.
