Replacing A Two Way Valve

[macca79]

I was recently helped on here with identifying a fault with my central heating system. (Thanks Gas4you!)

I thought I'd been able to fix the two way valve by moving the switch manually a few times. However it stopped working again last night.

I've decided the best option would be to replace the faulty part. I've managed to find the part required online here:

Is this the sort of thing I would be able to replace myself (compitent at diy but not a plumber) or would I be better off calling a pluber out to do the job?

Easy enough to change but dont use that valve use a honeywell otherwise you will be changing it again soon.

It could just be the power head - or are you convinced its the complete valve at fault?

Cheers, will take a look at the Honeywell ones.

I think it may just be the power head that's at fault as both the central heating and hot water are receiving water through the valve. However the switch doesn't appear to do anything when turning it on and off via the controls on the boiler. At the moment when I want to use the central heating I have to manually wedge the switch on.
