The main header of most cooling water system (supply) are monster in
sizes. In some cases a nonslam type valve will be required such as
those made by Mokveld. And in a few cases, the valve cant be operated
(stuck in open position). And when that happen, you cant work on the
cooling water pump (hte main line need to be isolated).
In most instances, cant use TDW to plug the line nor cant freeze the
line such as those done by Bishop (UK).
They're not sexy Steve, more like a pain in the butt.
