new pump

[scotch]

I am pretty sure my central heating pump is knackered(can't hear it,radiators hot upstairs-cold downstairs and v old)

It is a "Myson unit 3 ".

Can anyone help re a replacement for this.

Many thanks

It's old but a standard size . Eg a Grundfos 15/50 or other 5 metre head pump will be ok. Expect to change the isolating valves as well, they often leak.

It might just be stuck. Take the screw out in the back of the pump and try turning the shaft.

new pump fitted(Wilo gold) and isolating valves fitted-problem solved.

Thanks to all who replied
