I have two Reilang oilers; one works and one doesn't and I can't find out why the one doesn't.
They are very simple bits of kit – two telescopic brass tubes with a compression spring in them and a ball valve on the outboard end.
The ball is free to come off its seat, I don't see any damage to the seat, nothing else amiss that I can see but it just won't pump.
Anybody got any ideas what to look for/at? Is there another ball at the base of the spout that I haven't noticed?
