Today I started taking apart the forward head to get to
the vacuum switch on the expansion tank that is part of the Vacuflush head
system. The vacuum switch was not working properly so it would never switch
off after developing vacuum.
Of course this required dismanteling the drawer system and part of the
shelves in the forward head. That took a while with pieces laid out over
the v-berth and the dinette.
I started by trying to adjust the spring screw so that it would work the
switch but I ran out of adjustment. I had a new switch but the darn tank
was put in backwards so it was completely inaccessable. (just had a
dejavu..) Anyway, After full adjustment it still wouldn't shut off so I
decided to file down the pin on the switch. Almost got it but still
unreliable, so I decided to go ahead and replace it. It was not as stinky as
I thought it was going to be and it was difficult to unscrew. I don't know
why it was necessary to tighten it sooo tight. Well, I got it off and
replaced it. Now I know why it was so tight. It takes that to tighten it
up and not leak. But in tighetning it up it cracked and so now It works but it
has to re-pressurize/vacuum every hour or so. I've tried sealing the crack
but it's still leaking. I'm not sure it's the crack in the switch or a bad
duck valve. Why can't anything be easy? I'll post a few pics later. And of
course a new valve is $200....
tank mounted backwards so you can't get to it
$200 for this baby... and of course it's up against a bulkhead...
