atmosphere as it passes through.
It is also possible to fit the Venturi's inline so that they do
not protrude into the actual pond .. although the disadvantage of
fitting such is that without making provision, and using demountable
unions at either side of the connection, then it is almost
impossible to clean and service these inline Venturi's ... |
