Well I got my airforce pump in yesterday and it was not so bad taking it to 2000 psi for the first Disco and it took me almost twice as long for the second Disco I pumped it up to 2000 psi and about 4 hours later it was down to 1000 psi thinking maybe I didn't pump it all the way up so I did it again and I checked it this morning and it is back down to 1000 psi, so ? ? ? ? ?
Any help at this point would be good, I check the gauge and the fill adapter seem good to me?
