water. The resulting failure of the system to remain in operation is attributed to improper installation, is the
liability of the installer, and is not covered by the Sea Recovery warranty.
CAUTION: The Sea Recovery System must not be tied into another existing auxiliary water line already
supplying another accessory on the boat. Using one Thru Hull fitting for other equipment will cause the Sea
Recovery System to draw air or cavitate leading to continual system shut down. The resulting failure of the
system to remain in operation is attributed to improper installation, is the liability of the installer, and is not
covered by the Sea Recovery warranty.
CAUTION: If the Sea Recovery System is connected to a Sea Chest or Stand Up Pipe, do not plumb the Sea
Recovery System feed line to the "top" of the Sea Chest or Stand Up Pipe. If plumbed into the top of these feed
water arrangements, the Sea Recovery System will experience continual shut down due to air inducement into
the system. The resulting failure of the system to remain in operation is attributed to improper installation, is
the liability of the installer, and is not covered by the Sea Recovery warranty. Plumb the Sea Recovery System
to the "bottom" of such feed water arrangements to ensure a continual air free supply of feed water to the system.
Problems & Symptoms appearing and caused by the THRU-HULL INLET FITTING [1]:
a. Flat profile Inlet Thru Hull Fitting:
• System runs fine when at anchor. However, when under way the System shuts off due to low pressure
or low feed water flow.
A flat profile Inlet Thru Hull Fitting will cause a vacuum at the System's feed line cavitating the
Booster Pump and reducing the efficiency of the Booster Pump resulting in low feed water pressure and
low feed water flow.
Solution: Change the flat profile Thru Hull Fitting to a forward facing scoop.
b. Debris is blocking the Inlet Thru Hull Fitting:
• System feed water pressure is low and insufficient to keep the System in operation.
Marine growth or debris such as a plastic bag or rag covering the Inlet Thru-Hull Fitting will cause a
vacuum at the System's feed line cavitating the Booster Pump and reducing the efficiency of the
Booster Pump resulting in low feed water pressure and low feed water flow.
Solution: Clean all marine growth and debris from the Inlet Thru-Hull Fitting.
• System is newly installed and operation is being performed for the first time. The feed water pressure is
low and insufficient to keep the System in operation.
A NEW boat, or newly installed System, may have protective shipping tape covering the Inlet Thru-
Hull Fitting. A New boat, or newly installed System, may have manufacturing debris such as caulking
slopped over the Inlet Thru Hull or a rag may be stuffed into the Inlet Thru-Hull fitting. A NEW
Inlet Thru-Hull Fitting may have casting slag, that has not been machined off, partially covering the
"fingers" or the inside of the fitting.
Solution: Inspect the Inlet Thru-Hull Fitting and clean all manufacturing debris and casting slag
2. SEA COCK VALVE [2]
The Sea Cock Valve is usually a 1/4 turn Ball Valve although any positive closing and opening valve is
acceptable.
