Anybody have any advice on getting the dual head of a Planet Bike ST floor pump to work? I have used the pump for over a year to fill presta tubes - no problems.
Today I need to fill a shraeder valve and although the shraeder valve stem fits into the second hole on the dual head OK, there is no air coming through the head into the stem valve. As one pumps away, you can feel and hear the air coming out of the presta side. Used pumps with dual heads before and usually there is some type of lever to turn to direct the air. No such lever on this pump. The only lever is the one you turn up to lock the head onto the valve. Only seems to be one position for the lever, up or down.
Thanks up front.
