[C320-list] Seacock question

[Dave Hupe]

 Jack-
Remember that you will need 2 separate thru hulls for the AC pump system..... one intake water and one where the water is expelled. My AC unit is in the port cockpit locker.  The pump intake thru hull is next to my engine intake thru hull.  The thru hull for water exiting the system is above the water line on the port side just slightly lower than the AC unit itself.

 Thanks, all.

Jeff, mine is the same as yours. The fridge drains into the bilge. One outlet goes to the head pump and the other to the shower sump. I thought that was how it worked, but you know how it is when you try to remember things away from the boat when you’re in your 60s …

This is part of my scheming about air conditioning. A boat mechanic was recommending that I try to install the AC in one of the lockers under the V berth instead of the port cockpit locker. That makes some sense because the front of the cockpit locker already has a lot of 12 volt charging stuff.

That would give me two choices for an AC seacock. One would be the unused knotmeter hole. The other would be to use the through hull that now drains the head sink. We only use freshwater in the head for smell reasons, so I would drain the sink directly into the head.

The sink through hull is attractive because I could get it installed without an immediate haulout. The good boatyards in Florida often have a monthslong waiting list. 

I’m off to do some crawling around on the boat this morning to see whether any of this makes sense.

Hi Jack,

This seacock is a 180 degree seacock. All the rest on the 320 are just 90 degree seacocks. It does not matter which way you turn it to turn it off.  Frankly I prefer this style over the 0/90 degree versions because it's easier to keep the ball valve clean and you really don't have to remember which way the valve needs to be rotated to turn it off.

As for the "Y" valve, "more mature" 320's didn't come with one. Newer models have the fridge drain and shower sump going into a "Y" valve under the head sink so that the shower sump can drain the fridge or the shower sump.  Others still have added a "Y" valve into the Sink Drain line with the other side going to the head raw water intake.  That allows you to run water in the sink and fresh water flush with it.

Cheers!

I have two Marelon seacocks under the galley sink. The one that drains the sink is a standard valve in which the lever moves 90 degrees: Up to drain, down to close.

The second seacock drains the shower pan. The lever moves 180 degrees. It seems to drain when the lever is up and close when I move it to the left. I don’t know what happens when I turn it to the right. 

Before I do something stupid like remove the hose someday, I thought I’d ask the question: Is this the way it’s supposed to be? Or is the seacock broken?
