I haven't used my hill pump in over a year now. Tried using it today and it doesn't want to build pressure. Draws air and blows when not connected to anything.
But when connected it seems to build just a little pressure (nothing on a gauge) and the handle rebounds when compressed. almost like a one way valve isn't working.
Ive never pulled it apart...but my guess is its not the complicated. Would like some idea as to what could be wrong.

Don't own one or any PCP floor pump but just have one question. Have you lubed it with some high quality silicone oil?

Just ask yourself, have I pooped my pants today? If the answer is no, you're doing okay.

IMHO Sound like you're going to need to rebuild it then. I'm sure you can find vids on youtube that show how to rebuild it. I've seen one's on rebuild the Chinese and Benjamin ones and it don't look hard or complicated.
