Alert – Air Revolution Pump Failure
Yesterday, I had a worst case pump failure while riding the Franconia Notch Bike Trail. I noticed my rear tire seemed low. I had checked it before the start of the ride but things happen. When I put the pump nozzle on my tire, air started rapidly flowing out of the tire, the pressure relief button on the Air Revolution pump was stuck in the open position. I was not able to get the relief valve to close. So, I was stuck on the trail with a very low tire and a pump that will only let more air out of my tire.
I know I have raved about this pump in the past but this is a totally unacceptable failure. I bought the pump in the Spring and have used it less than 10 times.
My Rating for this Pump is now unacceptable.

Update 9/26/2006: I have analysed the pump failure and doubt that the pump can be repaired. The seal at the bottom of both cylinders failed and the cylinders are tilted with respect to the base. This must have happened when I was trying to inflate a tire on the road and the ground was not perfectly flat.
The pump cylinders do not appear to be well secured to the base and can be moved in the base. When the cylinder is tilted the seal at the bottom of each cylinder is broken. The construction does not appear to be sturdy enough to take the expected rigors of Bicycle Touring.
This is the second pump design from this manufacturer that looked good but is just not study enough for its intended application.
