[Public-List] Holding tank vent

[Randy Katz]

Greetings, Glen,

I ran my vent tubes (2 of them) from the holding tank (in the same location
as yours) through the bulkhead and up into the dorade over the toilet. No
bad smells fliter back to the cockpit. The photo in the A30 collection of
ideas and photos shows vents at the bow, forward-- what about water coming
down them during heeling?

I prefer my way-- it's a shorter run for hoses and doesn't involve piercing
the hull. Jamming the hoses up into the dorade was a cinch.

Hope this helps,
Best Regards,

Hi all,

I am replacing my old chain locker holding tank with a new tank and
plumbing. The new tank will be located under the port berth in the focsle.

There is an existing shut off valve  in the old discharge line that
isolates the old tank from the y valve and overboard valve both located at
the head.  Is there some U S requirement to have a shut off valve mid way
between the tank and the overboard discharge point?  If so, where should I
relocate the valve with my new plumbing routing?

Also, WITW (where in the world) should I route the breather tube outlet
from the new tank.  I sure  dont want to live with the fumes/oder of the
breather tube outlet in the boat, or outboard forward along the cabin top.

Thanks

Glenn
