Which direction do I turn this handle?

Default Which direction do I turn this handle?

I have a Forespar Marelon seacock under the head for seawater toilet flush that I want to close since we use fresh water to flush. I can't find the exact Forespar part number, but another Forespar valve diagram showed to turn the handle LEFT (blue arrow) to close, and that makes sense with the word OFF being "upright" even though these could be mounted anywhere. The arrow triangle in the molded handle points to the RIGHT (red arrow), but I assume that arrow is showing direction of operation when it is in the OFF position. This is plastic and the boat is in the water and I don't want break anything. What do you think?

that brand and type of plastic is approved for below water line use, the install itself looks like trash though lol

Yeah, that is why I am a bit worried about operating it, but the inspector turned it during inspection. I don't know what that white stuff is, I am hoping thread sealant, and not 5200 holding two incompatible parts together.

Do you think left is off? Here is another Forespar valve:

That should definitely be replaced, but Is it so tight that you do not want to turn it both ways just to see which way it will move? I think it should go in the direction of the blue arrow, but not positive.

It is in the open position in both photos.

i would be more worried about the install- as per the diagram above there should be a threaded fitting going through a backing block and a flanged valve attached to it. not a floating valve like you have there threaded onto a thru-hull

someone puts a little pressure on that or kicks it and it may just snap off- that is why they specify a backing black and a flanged valve

if you are not going to use saltwater flush ever and thats the only thing that fitting feeds take the whole thing out and have a fiberglass guy fiberglass the whole thing over
probably cost you about the same as installing the proper components

Thank you, it is under an access panel so it shouldn't get kicked, but it is still a worry. I will plan on addressing it the next time we haul it out. I will carefully close it for now and keep toilet bowl wax on board and some plugs.

The handle clearly shows an arrow and the word "off" along with a two additional arrows showing the open position with "flow". Currently it is in the open position. Turn the handle in the red direction as indicated by the arrow above "off".

Not sold. Curious. Curiosity killed the kat though right.

My Rampage came with Forespar thru hulls and it didn't matter which way you turned them. They are ball valves and if you wanted to close them, turn right or left. Just remember straight up is open.

regardless of the lack of Flange that’s not a good install. Was the salt portion of it installed after the boat left the factory?

I’m sure it will be fine for now

imagine a gorilla turning that and snapping it off. If it’s a bottom painted boat (be cheaper than no paint ) just remove it and have it glassed over and have one less below waterline connection to worry about.

The convention with any ball valve is..

When the handle is perpendicular to the directionof flow it is closed
When the handle lines up with the the flow it is open.

This.

In regards to the concerns about plastic, does that valve go through your hull, or into a holding tank?

it feeds his toilet through the hull, if it were going to a holding tank discharge it would need a lock on it to be legal in coastal waters of the US

I thought that looked pretty obvious also.

"OFF" is in the orientation of your RED ARROW.

FWIW: it may be more appropriate if handle indicated OPEN / CLOSED

Valve is Marelon which is approved and what I have on my Sabre, the through hull however is plastic and not an approved install.
