How do I fix a leaking bike pump?

Repair a leaking pump head by unscrewing the nut and replacing the seal. If the head is leaking at the connection to the hose, replace the connector with an adjustable hose clamp. Tighten a leaking fitting at the pump end of the hose where it screws into the base of the pump.

How do you remove a bike pump without losing air?

How do I know if I have Schrader or Presta?

The visual differences between the two are obvious, with the Presta (pictured above) being slimmer, lighter and having a lock nut to close that you can see on the top. Schrader valves are wider, more robust and have a spring mechanism on the inside to keep the valve closed, rather than a screwable top section.
