Keep an eye on how your tipups preform ,all makes and models will leak lubricate from trip mechanism over time .If things get worse contact Jack Traps and ask how to re-lubricate your tipups. I'm not sure if this is possible you may have to replace the trip mechanisms. I know on broad/rail style tipups you can take apart the mechanism remove the old lubricant ,relube and put everything back together. Also if you check a tipup and notice line out and no flag up or you have been spooled ,you are probably loosing lubricant and water is getting into the trip mechanism and causing it to freeze up and not trip.
I hope the Jack Trap rep. was correct and it is not any thing major.
