Paul – great blog, lotsa detail. You have piqued my curiosity with your
active holding tank vent project. I have a rather ‘piquant’ poly holding tank
in my 33-2. I changed the in and out (but not the vent) hoses and still I get
a stench, particularly when the adjoining lockers are opened. The tank itself
was removed and repaired, and while out it could not be de-stinked by any means
I attempted, bleach, etc. Maybe there’s a way to deal with that, dunno.
Am considering replacing the tank, but would rather resolve the cause. (or do
both, and make provision for better/active ventilation in the new tank)
In your post below, you seem pretty pleased with the result, any other
insights? Anything you would do differently?

Hi John,
I have recently gone through much of this with my LF38, and I have written
much of this up on my blog. The first link below discusses the head plumbing.
I went with a macerator pump rather than a hand pump. Read the section on my
?Sanitation System Plan?.
In my setup, all head waste goes directly to the holding tank. The holding
tank is emptied via a Y-valve either at the deck outlet or via a macerator
discharged overboard below the waterline. The key here is All of the waste is
pumped into a holding tank. When there's no Y?valve between the toilet and
tank there is no legal requirement to lock a valve or seacock. On the other
hand, installing a Y-valve between the head and the holding tank makes one
legally required to lock/restrain the Y-valve closed when inside the three-mile
limit. Not having a Y-valve before the holding tank gives authorities no
reason to get upset. Also, I have added an affordable (~$20) active
ventilation system to the holding tank(see second link).
It's been in use for nearly a year now, and so far with plenty of use there
are absolutely no bad smells in the head.
Lastly, I have added a link to my LF38 projects page.
