pump

Been given a new pump purchased from Tescos, its one of these new
small design things with the connection at right angles, the thing is
I have no idea how I am supposed to connect it to my valve, there is
no seperate connecting piece and the actual pump end does not have a
thread, is it just a push on connection and if so I would have
thought it will soon wear to be a loose fit ?

Yes most modern pumps simply push onto the valve. The washer can wear
out, but if you're lucky that won't be before too soon. It may be
replaceable.

Most of the better pumps have a lever that tightens the connection after
the pump is pushed on to create a better seal and save wear and tear on
the washer. However, I've noticed some of the latest super-light pumps
without levers have quite a different sort of washer from the usual that
hopefully will last well.

I don't know what the Tesco pump is like. Might be a good idea to get
something more reputable if going on a long ride!

Thanks very much for that, I will give it a try.

Being a cheap pump, it might be a matter of loosening and then tightening
the knurled ring around the end of the pump. This places pressure on the
compressible rubber bit in the end of the pump.

The ancient super-cheap SKS all-plastic ones had this arrangement. They'd
work for a while, but I found the plastic lock-rings would split. I now use
better quality pumps with a lever as described by Pete.
