I have a Lezyne Sports Drive floor pump. It has worked fine for a couple of years, and it lives in my garage. The handle is stored in the down position, so the cylinder is mostly empty. The pump sits on the concrete floor.
Today I went to use it while patching a road tyre, and pushing the handle was hard, and there was no air entering tube till the gauge hit 80psi. The tube was not at 80psi - it was naked and maybe held 5-10psi.
I checked the schrader/presta adapter/pressure release thinking something was stuck in it, but that's just a threadded tube and was clear.
So I checked with the hose nozzle in my and it blew air with no resistance. BUT it was very cold and my hand got damp. Imagine a wet sneeze, but cold.
Aiming the hose at a clean dry surface, I gave it a pump and there's moisture visible. 30-40 pumps later the moisture is much reduced.
- Does my pump have water in it?
- How did water get in there?
- How do I get it out?
