Usually, with the Omni wrench, its simply a matter of unscrewing and spinning the filter holder off, replacing the element and rescrewing it back on.
However, for the past few months its a herculean effort to unscrew the filter holder. I must brace the entry and exit pipes and really put some muscle into it. So much in fact that I'm afraid of breaking it.
I've inspected the inside of the device and it all looks normal and there is no goop around the threads or anything.
Does anyone have any ideas or suggestions as to why this might be doing this and, more importantly, what I might be able to do to relieve this situation?
