Central Heating pump
 

Trying to replace pump. There are two valves either side of pump which I
thought would switch of water but after fully closing them I still get water
coming through. Any suggestions?

Drain the system and then replace the pump and valves.

The valves are more likely quarter turn flap valves, so you only need to
turn them to the slot at right angles to the direction of the pipe. So the
slot for the screwdriver would be
" -- ~ -- " for on and " -- | -- " for off, with anything other than that
letting water pass.
