Tank systems

[keithgdg]

One and all,

I am fitting my grey and black systems in at the moment ready for the great escape 06/2014. Can't come soon enough IMHO. However I have come across "anti implosion vents", not previously known about. To fit or not to fit in addition to the 25mm thru hull vents being fitted that is the question?

Any takers on advice please?

I think "anti implosion vents" are fitted to avoid the holding tank being ruptured during shore based vacuum pump out. The 25mm thru hull is for general anearobic ventilation but I would have thought that it also acts as the anti implosion vent ie you dont have to have both.
