    I suspect your problem will be with the inner tube not the pump. Was the inner tube Continental? If it was you need to make sure that the valve core is fully tightened.

    I have two of these:
    not cheap, takes a bit of pumping to achieve very high pressure but pretty good.

    Hi yes it was a continental tube

    Also dont tighten the valve core too tight otherwise you could split the valve tube.

    Try not to tighten the pump so tight on the valve next time and it wont unscrew the valve core.

    It's not the pumps fault. :twisted:

    use thread lock on the valve core threads and/or don't use a thread on pump on a removable valve tube. the topeak pump works very well for a push on mini pump. push on co2 is the future!!

    Hi thank U all for the quick replys looking at them looks like it could have been user error do U use a core valve tool to make sure they are tight or just fingers . Yes think I will go for a push fit pump rather than a screw on type

    core valve tool (little plastic thing) and threadlock

    some screw on pumps/or their users... suck, stopped to help a random the other month and they had cross threaded the pump onto the valve and had been stuck there for 35mins! had to use two tyre levers as leverage to get the thing off. then used my lezyne micro drive to sort it for them.

    hold the valve stem with pliers, use a core tool or another pair of pliers to tighten the core, then it won't come loose

    having said that, i've found the screw on heads eventually wear out, i got a push-on one as replacement, makes life simpler
