Modify the adapters and the noise goes away,
Verified Purchase(What is this?)
I bought this foot pump because I had used a similar model at a music festival and found it to be very effective.
This pump, on the other hand, emits a whistle so shrill that it was actually physically painful. I wasn't able to determine whether the pump even worked at first because I couldn't use it for more than a few presses before stopping.
Then it struck me: the adapters for different types of nozzle reduce the noise, so if you just saw off the of one of the adapters, it creates a silencer that reduces the whistle to a tolerable level. Now it works just fine.
