My Air Tower 3 now refuses to pump into presta valve. It just hisses at me.
I’ve searched and found that most parts are replaceable – the bit that doesn’t work is the two-headed end bit that you actually connect to the tube valve – one bit is presta, the other is shraeder. It worked fine last week, now a refusal. Will just pump shraeder. I can unscrew this top piece, but where can I find its replacement? Somebody must sell them – a pity to ditch the whole pump and spend £30-£40 on its replacement.
Ideas please if you’d be kind enough. Thanks, Richard.
