Seacock strainer
The seacock strainer must be cleaned regularly, especially if there is a large amount of small debris in the
water.
Corrosion
This can occur when two different metals are in contact near to, or in, sea water. For example, a brass or bronze
pipe tted into aluminium can cause rapid corrosion. For this reason, special precautions are necessary when
an engine is installed. In this situation, some components will be connected to a sacricial anode tted to the
hull. Specialist manufacturers will advise on the maintenance of these anodes.
