I somehow ended up with a presta valve inner tube from halfords, which I must have bought by mistake as I normally get the shrader valve inner tube.
I have the ferrex pump from Aldi and it comes with a presta valve adapter. When I press the lever down on the ferrex pump to lock the valve and start to pump, air comes out of the valve and I have to pump with the air coming out! Am I doing something wrong? When you press the lever to lock, the air should stop coming out of the valve so you can start to pump.
I also have a bike pump from Halfords as below, and I can't get it to work with the presta valve, with or without the adapter.halfords.com/cyc…d=t
