Sewage holding tank air bleeder outboard location

[biggslaw00]

Catalina hull no. 747, 1978.

Where does the holding tank air bleeder hose likely vent over the side? The hose from the top of the tank disappears under the cockpit sole so I can't complete a physical trace and I don't know what to look for on the exterior of the hull for the vent.

Any suggestions or pointers would be most welcome.

Look at the stanchion base nearby. There will be a small hole near the base.

It's called a vent, not a bleeder.

yea and peggy hall will tell you to get that hose off of the stanchion and install a through hull mushroom fitting high up on the top sides and put the hose on there for better ventilation ... a 3/4 inch or larger and if you need to put on a new hose of correct size

Umm, stanchion nearby what?

thx,

Stanchion nearby tank. If tank is midship starboard side, vent usually goes to next stanchion forward of tank starboard. As Stu mentioned look on the inside of the stanchions midship near the base, the one with the vent will have a small hole.

The effluent holding tank is located port side midship - not stbd - under the saloon settee between the head and the galley. Vent hose runs from top of tank aft between batteries and engine and under cockpit sole, which is why I can't trace it without being able to slither in there like a lizard. The only hose I can see that goes topside connects to the pumpout port. Looks like this is a custom installation and I'm going to have to rely on my own ingenuity.

Thanks all.

ITWMB, I'd check carefully again. The vent hose should NOT run as you described it. Find the vented stanchion on the port side, first. That's where it should be. If the vented stanchion is there but there is no vent hose connected to it, it could allow water into the boat down the stanchion tube itself. In any event, correct the wrong holding tank vent routing. Do you have a C30 manual?

You're right, the most frequent source of difficulties is operator error. Will check as you recommended next week and also pull out C30 publications I have. Not sure if any of them really qualify as anything approaching a comprehensive operating manual. Sounds like searching for the exterior vent is the new first order of business.

Thanks again.

Use Google, find the manual. Good luck.

It should run into the lport side cockpit settee locker and then up into a stanchion. The holes--not much bigger than a salt shaker--are often on the after side of the stanchion.

If yours runs under the cockpit sole, a PO may have relocated it to the transom in a misguided effort to eliminate odor from the vent perfuming the cockpit when the toilet is flushed. So check your transom for a vent thru-hull.

My vent is visible on the outside if the hull just below the yellow jerry can.

It's behind the cabinet in the head. I just replaced mine

There is a manual??

A very good manual! you can purchase one at the store here or look for on online.

I checked, and the vent hose runs aft under the cockpit sole as I remembered, not up through the locker to a port-side vent. The portside stanchion doesn't have salt shaker style holes in the base, so a PO has in fact re-routed the vent toward the stern. Now will try to isolate one of the transom vents to the holding tank hose.

Thanks for all your input.
