Cockpit Drain Seacock too tall

[mitiempo]

A Groco flanged adaptor with an elbow and then a ball valve will work as well as give you the best attachment to the hull. Flanged Adaptors

You install the elbow to the flanged adaptor and then the ball valve as shown below.

Unless the thru hulls are closed or 2 inches above the cockpit drain the water should get out. I understand you did not change the cockpit fitting. Confused.

This is a much stronger setup than just screwing a valve on the thru-hull and it still keeps the low profile you need.

Thanks for the tip. Is that an item you keep on the shelves in WPB store? I will be passing through in about a week.
As of now I dont have valves on mine. It is a constant point of concern as the thrus are below the waterline.

???

1. No best practice but one sees it a lot.
2. Do you mean above the static waterline or below?

The right side shows my current setup with thru hull, seacock, 90 hose fitting, hose. The old gear stayed below the cockpit floor (blue line). The height of the seacock in the new setup causes a sort of loop above the cockpit floor level. Water drains to the red line and then stops.

This happens in a static situation. Crossing or not crossing won't fix it. I need to bring the entire setup back down to below floor level. Need a shorter seackcock or go back to elbow and valve.

Ahh.... a picture is worth a thousand words, I see your problem (and feel your pain ).
I think you are right (as is Barnakiel), you don't have many other options (none that I can see) if you want to keep the original holes in the hull.

I don't know what your setup is like under the cockpit but I have always favoured having the through hulls much closer to the keel line than away from it like in you instance. I understand that this may not be desirable in all situations due to conflicting requirements for space and access!

My ideas:
a) go back to the old set-up,
b) move the thruhulls under the cockpit.

See image, it makes the OPs position quite clear!

Yep, you are right, it is a bit hard to find, go to the photo's tab right at top of every page, pull down menu to maint. & boat bulding, chose date first (or whatever) and find a photo from CAS206. when I looked, it was the first one.

Greetings and welcome aboard the CF, cas206/cas20636.

I’ve alerted the Moderators about your posting problem.

[HopCar]

SailboatLarry, Yes we stock them in West Palm. Let me know what size you need and I'll have them set a couple aside for you.

[cas206]

Mods fixed me. As a new user I was heavily filtered by the spam guards. I am supposed to be cleared. Hopefully this post will post and the picture will become part of the thread.

Thanks for the two product suggestions so far. I think the plan of attack is to measure the depth of standing water in the cockpit to see how much I need to reduce the seacock height. Then I'll find (hopefully) mechanical drawings for the products listed so far and compare to the Forespar parts to see what I can get away with. So far my priority list is 1) shorter seacock or 2) flanged elbow + valve or 3) back to the way it was.

[HopCar]

CAS206, If you let me know the size of your thru-hull, I can fit all the pieces together and measure the height for you using the Groco Flange Adapter and a street elbow. I'm guessing it won't be any higher than your original set up. It should be at least a couple of inches shorter than any seacock.

cockpit drains in cockpit are screen-like discs flush mounted into the drain holes...the under deck stuff is not spozed to leave water in cockpit. i do not see where the problem is for the water remaining in cockpit well. is there a lil addition that requires removal so a flush mounted screen can fit?

The problem is physics... water won't go uphill...not without a mechanical apparatus to pump it. Once the water in the cockpit reaches the red line of my picture, the water in the drain hose has to go "uphill" at the hose / elbow joint (right side), and then back down in the seacock/thru hull. It won't do that naturally. The water is in static equilibrium at the red line.

I tried posting a picture of the old elbow and valve with ruler, but my phones USB cable has apparently died. Anyway the thru hull's (two) take a 1.5" valve. The elbow comes out between 2.5-3" from lip to top of pipe.

Thanks,

my thru hull cockpit drain hoses donot cross over and i have yet to find a problem. mebbe that is your problem. uncross them and see if that helps. min ego thru on the side they cover. straight out no monkey business with crossing hoes over to other side.

Zee, click on the image in post 24 and the problem becomes obvious. The left hand side is original, the right hand side is the new arrangement (with problem).
