Is "tap" a proper word for water-pipe switch?
I'm looking for some kind of tap /switch to open /close the tubing to the
ballast tanks.
Since one of the main goals is to keep empty weight down beg metall things
is not acceptable.
The pipes (plastic hoose) must be 15mm (dia), maybee 20-30mm.
Hints please!
