Clearing An Obstructed Thru-Hull
Steps
- Shutdown the water-dependent system and close any seacocks
- Disconnect the hose or pipe connected to the seacock
- Select a sealing stopper that seats securely in the open end of the seacock and place the stopper on the control unit
- Connect the control unit to a garden hose, close the valve, and turn on pressurized water
- Position the sealing stopper in the seacock and open the seacock valve
- Hold the stopper securely in place and open the control unit water valve, forcing water out of the thru-hull and clearing the obstruction
- Close the control unit water valve and the seacock, and reconnect the pipe or hose
No water enters the vessel through the thru-hull!
BlastItOut does not need to be connected at the seacock. The pipe
or hose can be disconnected (and BlastItOut inserted) at any
point between the seacock and the water-dependent system. If the
disconnect is done at a point above the waterline, no water enters the vessel
at all.
