Today I got to work on my sump. Fun times until I hit a snag... ugh... again. OK I don't have pics to post so I will need you guys to put on your imagination hats on.

That said I will have a busy week getting the wall opening and stand leveling properly prepared.

Since then, I have been executing them on a regular basis - but for every one I kill, I suspect there are 20 I don't see. Not sure if they're OK or not, but I just realized that ...
