I have a cheapo £5 foot pump that came with a presta to schrader adapter.. When I put it on and connect the pump, it leaks at about 5-10 psi/sec - so I have to compensate by rapidly pumping to reach a max of around 60 to 70 psi (according to plastic glued-on gauge).
Is this a common problem w/ these adapters or am I doing something wrong? Should I try a new adapter or do I just need to pony up for a proper track pump?
