Unclogging a waste tank vent
 

Does anybody here have a quick and easy way of unclogging the vent to a
waste tank? I suspect that there is a clog because as soon as I open up the
pumpout even after minimal use, gas escapes as if the tank was under great
pressure.

He doesn't know. All he knows is that he has pressure. I'd say he outta
try a small snake from the vent outlet toward the tank.

Then he should just pull the line off the thru hull fitting and give it a
blow!!! If the line is open, the clog is in the thru hull. If not, it's
fishin' time.

I'd recommend using a set of unsuspecting lips or an air hose.

I could swear i just answered this question here...

First, do not use your toilet again or try to pump out or dump your tank
at sea until the vent is clear...a strong pumpout pulling against a
blocked vent can crack a tank...flushing the toilet enough times can
pressurize a tank enough to crack it.

The two most likely places for a clog to occur in the vent are the
thru-hull and the vent fitting on the tank....especially the vent
fitting if seeing the tank overflow out the vent is your idea of
determining when the tank is full.

Dirt dauber, dust, pollen etc can clog up a thru-hull very easily, as
can spills out the vent. So check it first. If backflushing with a hose
doesn't clear it, you may have to dig it out with a screw driver blade.
If there's a screen in the thru-hull, don't worry about puncturing
it...in fact the best thing you can do is get rid of it. If you don't
find anything in the thru-hull, remove the vent hose from the tank to
check the fitting and that end of the hose.

If you want to prevent this problem in the future, NEVER allow your tank
to overflow...if you don't have a gauge, install one--and pay attention
to it. Blast out the vent thru-hull with a hose every time you wash the
boat and check it regularly to make sure that just blasting it out is
enough to keep it clean.

You also need to check the thru-hulls for your water and fuel tank vents
regularly, and make sure they don't ever become blocked.
