The rest of the tubes seem to stay inflated well, all seem to loose some pressure if left standing for a week or more, but this particular tube looses pressure within a few hours...... Soap and water test I think ...... I know punctures can be repaired but I hope it's just the valve, quick easy and cheap fix
