[PSUBS-MAILIST] Main Ballast Vent "T".

[Hugh Fulton via Personal_Submersibles]

Hi James,

I had a similar problem with the Comsub.  When it gets a bubble the vent is in the wrong place.  Centralised venting can create problems.  I am going localized pilot operated venting.

Regards,  Hugh

Hi Hugh,  Drawing is not to scale or anything, it was just to give you an idea.  Anyway, its going in this weekend.  I know where the bubble is.  I think maybe my tanks are not as steep a profile as original Kittredge ones.  Maybe that's why I get the bubble.  Anyway, im pretty sure this will cure the issue.

 

Regards

James

Hi James.

Turn your drawing at the angle you think you want, draw a line horizontal, then see if the outlet is above the bubble.

Hi All,

 

Im going to T in another vent pipe into my main ballast tank at the back.  Unless I submerge perfectly straight, I get a bubble stuck in either the front or rear tank. 

 

If I T in this vent extension to the existing line, I can dive nose first and still get the bubble out.  I cant see anything wrong with this, but I though id ask in case anyone has any thoughts?  
Thanks

James
