Hi Guys:
My Topeak Joe Blow Sport pump took a dive on me after many years of
use. Instead of buying a new hose with fitting, I decided to buy a
new pump. I purchased a Topeak Joe Blow Pro with a flip lock switch
nozzle that is able to accomodate Shraeder & Presta valves with the
same nozzle.
Although it pumps very easily, I have noticed a very "annoying" side
effect. I pump my tires to 120psi and after unlock the head via the
flip lock switch, I remove the nozzle from my presta valve. I notice
that there is a loud hissing noise. At first I thought it was from
air inside the hose but after checking the pressure in my tires, I
find that the tire has lost 5-10 psi. Is there a way of preventing
this? I tried a Blackburn Air Tower 5 with a similar type of inflator
head and it has the same problem.
Any help is appreciated.
Thanks,
Claude
