Hi everybody,
I went to my LBS and explained about my pump problems. A mechanic said I needed a gasket in the pump head and a new gasket was installed. I asked the mechanic to test the pump on a Presta valve (not mine). In order to get a tight seal, he really wiggled and jammed the pump head all the way down on the valve. Is that the way a pump head should have to work? Was my pump head really fixed?
