I bought an alloy floor pump of all places at Aldi for $8. It has a gauge and dual head. Surprisingly, it has lasted for 2 yrs so far.
However, my 5-year-old got ahold of it the other day and unscrewed the top and pulled out the plunger. I did not see any other parts lying around, and put it back in with the o-ring intact. Now, it makes a popping sound at the bottom of every stroke, and the gauge goes haywire.
Any ideas on what part might be missing?
This sounds like a challenging one to me, so I will be grateful to the wizard that figures this one out. If a pic is needed, I can do that.
Thanks in advance.
