Galley saltwater source from coolant line?

[swiftwaters]

I have an 8.7 meter columbia 1977. I have 2 seacocks in the galley, one is solely for draining the sink, and the other is solely for the coolant intake for the engine (its saltwater cooled).

My saltwater sink is not hooked up at present, and I am wondering if anyone has any knowledge as to weather it would affect anything if I had my sink draw from this line with a bronze Y fitting for example.

I am unaware if the foot pump remains sealed when the pedal is not depressed, but I am curious if I were to do this if:

A) water would make it out of the sink due to the head created by the engine
B) would I affect the cooling efficiency of the engine or
C) any other problem I may have missed with this situation.

Thanks!

Second that. Several things could go wrong doing this. Sure, if you're lucky it can work OK but if you suck air and overheat your engine it will be a bad day.

What I would do , use the sink discharge as your new pickup . For a sink discharge drill a new hole several inches above the water line and to the rear of new sink pickup ! Of course you will have to watch that you do not draw your discharged dirty water back up into your sink . All the foot pumps that I know off will not pass water unless you are pumping . I used seawater for washing and cooking for twenty plus years and it ain't kilt me yet !

Mine is plumbed this way. PO said it has been that way since the boat's beginning. Will be installing a shutoff valve to prevent air pull under vacuum with engine running.
