I get air in the pump on low speed, seems to be ok on high. I replaced the T ring gasket in the lid. The lid doesn't fit as tight as it did when it was new. I am thinking of getting a pressure test o-ring and trying that. There is quite abit of flexing in the pump lid when switching between speeds. The cam action lid leaves no way to make it tighter.
Any experiences or suggestions would be appreciated.
thanks,
Dave
