Every year after an extended cruise, I stop at the pump out. Hook up the
suction hose, open the clean out and spray water in the tank while sucking out
the tank. This helps keep the odor down, especially being a live aboard.

Thanks Paul, you've got me thinking....I know the vent works because the guy
who did the last pump out commented that he liked the location because he could
hear the vent. So, it is admitting some air, but day in day out, not a lot
because it can't circulate. Any reason you can think of not to create a vented
deck fill? Big boats have big vents... Same thing, I would think.This may
not solve the stench-permeated tank issue, but it would air the tank.

Dave,
>From what all the experts say, using quality hose and having proper
>ventilation are main keys. A real eye opener for me was finding
a bug nest clogged air vent line, so at the very least check or replace your
vent line. To be honest, I cannot make any claims that adding the
active ventilation fixed any problems as the system was be newly installed so
there was no problem to fix. But at such a small
cost ~$25, it was a no brainer to install a system which constantly pumps
fresh air into the holding tank. I thought briefly about getting a
12V air pump, but if I were to make any changes it would be to plumb the
galley sink drain to the head inlet so that when I leave the boat for an
extended period,
the head inlet could easily be flush with fresh water. This eliminate salt
water organisms from the inlet line which die off in
the line and decay, without oxygen, anaerobically.

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?
Dave
