I run an overboard. No idea why you would want any water coming into the boat when the idea is to keep it out lol.

LOL ya I agree. Thanks.

Would it be possible to tee that dump into the dump line for the engine water?
Not that I a opposed to drilling more holes in my boat. LOL

I actually can say it helped me.  I noticed last year I would have just a little bit of steam coming from my breathers on the valve covers and notice some oil residue on the bottom side were they vent.  This year I am running with the PSI relief and I have no more issues at the breathers.

It would completely defeat the purpose of the relief.

Think about what you just said.

I get the whole back pressuring the system part.  I asked wondering if i was to tee it in right at fitting going out the hull, would the flow there be enough to dump the water without causing it to back pressure. 
I have read a lot of your posts so thought maybe you would have some thoughts on that.

The restriction for the entire system is in the dump fitting in the hull.

Make this larger and smaller and it changes how much water the system can flow.  That is where the biggest (besides the gate valve) pressure drop will be.

The pressure before the dump fitting is the same as system pressure,  by tying in at that point,  the relief would never open,  the pressure on both sides would be virtually equal.


If you up sized the dump fitting,  you would be defeating the need for the relief valve to begin with.

Savvy?

Ok.  I smell what your stepin in. Lol.  Thanks for the info

Lol,  cool.
