live well pump question

Hi
Is it normal that water picked up by the seacock runs freely through the live well pump without the pump being turned on?

My new to me boat has a live well pump which feeds into my fish hold.
The challenge I have is while underway, if the seacock is open the live well fills up.
If my drain is plugged (with a plug or fish or other stuff) the tank over fills spilling into my gunnel foam and making it's way to my bilge. (though the hose hole cut into the fish hold).

Yes i can close the sea cock but my crew is often new and forgets, and the handle is out of sight. ( after market, was installed by the previous owner)
Yes I can plug the hose hole and yes i can install another valve to shut the water off at the fish hold but it seems odd the water will flow freely through the pump when the switch is not on.
Any thoughts?

it depends upon the pump's design...some will free flow (in either direction) and some wont.

My guess is that at some prior time, the original pump was replaced, and the replacement used a different design...

Sea cocks that are 'hidden' are a potential disaster just waiting to happen...
 
yea, I've added a sea cock close handle easier to see and am putting in a back up value to shut down water to the fish hold.... the pump i have turns out lets water in without the electrical switch on. poor design I'd think.
