Ye,my pump got zero resistance when trying to pump!?…. when i take the shaft out & stretch the oring it seems much better for a bit,but then goes back to useless again?… anyone had the same?.. pump 3 yr old but not had much mega usage??? Ta

Probably just worn away so not making a seal. You can buy rebuild kits or just find the correct o-ring. THis has revived dead mini pumps for me but my joe blow has been fine for years.

Ah cool…will try find rebuilt kit…dissapointing really,as you say most track pumps go on forever..thought would be trouble free buying a benchmark pump….. ;/
