Diverter valve

[theone8181]

Hi all I have a valve on my central heating that flicks between HW and CH. I've noticed that it seems to get stuck sometimes when it should be only running HW (i.e. some water goes through the rads when it shouldn't). I've changed the motorised bit so I assume it's the vale that's the issue. Is it worth trying to clean it up, or am I just better doing a straight up replace? The valve does seem to move reasonably freely, however it might not go fully to the HW side which could be why it's getting stuck.

I'd try cleaning it up first... Might just be a bit sticky and gunked up.

It depends on the price of the part. If it is cheap just replace it.
The same time and effort in taking it off and putting it back on but you know you have a good one for a while.
If its expensive try cleaning it as you have nothing to lose but the time and effort

Not worth the time and hassle trying to fix for me doing it for a living as its just an invitation for callbacks 3 weeks later.

It would be quicker to swap it for a decent quality new one and be done with it if you don't mind spending the money.
