Lol, now I know how to use a water hammer, thank you.

Had a new pump installed on my, sealed gas, hot water system. I've been
trying to balance the radiators. The pump has started vibrating on shut off.
Is there any way of fixing this, without getting the plumber back.

Sounds like your pipework is oscillating from the rotor unbalance vibration. I'd try

1. Clamp the pipes firmly to the wall as close to the pump as poss
2. Ditto a metre or so away as well
3. Or maybe fit a better pump.
