Perhaps this should have been a poll
Anyway, I'm in the middle of a re-fit and one of the jobs is replacement and repositioning of the holding tank
The new tank is roughly rectangular in shape and mounts on edge under the side deck
directly under the deck
As such it's a straight shot down the dip tube with no bends to contend with.
I have a choice to make regarding the manual pump-out scheme.
I can either use a "sanitary tee", with the run of the tee to the deck and the branch of the tee to the Henderson or use the dip tube for deck suck-out only and use a bottom outlet to the manual pump
With a sanitary tee it's an easy job to disconnect the hoses, cap the fittings and the tank can be removed without any chance of "unfortunate happenings".
With a bottom outlet the plumbing
is much simpler, and the runs are shorter.
However, should service/removal be required things get more complex.
The Henderson has easy access, and a bucket can easily be placed so that upon removal
of the cover/cap the contents of the hose can be contained.
I'd be interested in hearing what you guys think of top outlet vs bottom outlet.
I'm sure that horror stories abound no matter the choice.
