Thanks for the replys.
Took it back to the closest Opposite Lock which at the moment is Alice Springs. There is a leak but they can't fix it, according to them it has to be organised by the initial branch that installed the tank. Thank goodness I am heading back up to Rockhampton in 3 weeks...
Opposite lock 160L tank
I've got an opposite lock tank. Haven't been able to fill more then 140l from new otherwise it leaks. Does anyone else have this problem? Do they come with an overfill valve or should I get back in contact with opposite lock?
Thanks
