Second slide valve

We made a bracket out of 1/8 aluminum to hold the second slide valve in place.  We used SS screws and Tef-Gel anti-seize when tightening the screws.  We haven't decided yet how to operate this valve yet except to crawl under the coach to open it.  Hopefully the macerator will work and we'll never have to open this valve when traveling.  However, when we winterize the system we open it to get out as much liquid out of the black tank system as possible, close the valve and then run some antifreeze into the black tank and run the macerator for a few seconds.
