Have you tried to find a solution for Mabuk? How do you stop the water
from a leaking seawater valve?
If you have given up, or you want to see how he finally did it, please
scroll down the page and see.

First, Mabuk cut a piece
of sheet copper to the shape shown on the left.
Because the pressure of the water is quite low, probably less than 0.5
bar, he is confident that a 2 mm thick copper plate will be able to withstand
it.
The diameter of the plate is made slightly bigger than the pipe orifice
of the pump.

Then, he loosen nuts and
bolts of a flange that is downstream of the leaking valve.
He also removed one or two of the bolts so that he is able to slide the
blank plate in between the flange faces. The protruding part of the blank
becomes useful for this purpose.
When sliding in the blank plate, he is very careful not to damage the
rubber gasket.
He also makes sure that the gasket is at the water side, so that it is
able to seal the water.
After the blank plate is located at the center of the pipe orifice, the
bolts and nuts are installed back and all are tightened back.
The blank plate will be able to seal off any water from the leaking
valve, and the water will be completely stopped.
