Had trouble a couple of weeks ago with my pump not priming itself. In a panic I bought an identical new shurflow. However when I took the top off my old one I could see nothing wrong with it, put it back together and it worked 

Today I got to my first job and same again  Air lock that the pump couldn't cope with. Finally got it going (whilst the customer shouts out of his window "not today"    )

When I got home I fitted my new one - this easily primed itself sucking through completely empty pipes and strainer and even ran at 3 instead of the usual 7 on the varistream.
Trouble is I can't hear the new one 

Is it worth fitting a service kit to the old pump, bin it, or sell it to a newbie?
