Maintenance on electric head and pumpout

[Legend]

I have a 2004 Sailfish and yesterday I was checking all the electrical systems prior to my launch next Saturday and luckily all went well. Does anyone do any maintenance to the head system. I have never done anything but winterize it ?
Thanks

I have yet to have any problems, (knock on wood), but I have been pretty good about using this stuff.

Does it help? I guess we'll see.

Thanks I'll try it - got to be better than pulling that contraption apart!
