For easy removal of the OM-4 I still like the idea of a TUBV immediately below it.
Having the experience of removing and maintaining them - from under the tank, in the stand (can you say CHIROPRACTER...?
) a few times - I can tell you it is far easier than any other way I have tried to plumb them.
You will still need a towel to catch maybe a couple of ounces of water - but what other method is completely dry?
Untamed:
I just saw in an earlier post that your OM's have a 1/4'' drain plug? I guess mine are of an earlier "vintage" - no plug, but what a good idea. I may remove mine and install one!
