After finding myself stranded with a knackered pump recently, is it fixable?
It's the second pump (different models) to fall when needed this year for me, whereas previously I've had pumps for decades in similar service. It's only two years old.
Symptoms:
The pump delivers pressure, but then air comes out at the handle end when the pump is fully extended. You can hear and feel the leak.
My son has an identical pump, so I took both apart. Mine had a lot more crud inside and some corrosion on threads of the shaft, but the barrel seems fine as far as I can tell.
The internals of the working pump seemed exactly the same - O rings in the same places and looking OK on both pumps. More surprisingly, his pump still worked when I reassembled it
I greased up the o rings and other contact points, no difference.
I can't work out how to take the head apart. Is there a non return valve in there that's the issue perhaps?
It's a Topeak road morph.
