I have a small, intermittent leak from the actuator pin of the 3 way diverter valve on a Potterton Gold combi 28HE. Everything works perfectly, but the leak is sufficient to require re-pressurizing about once a week. Does anyone know if there is a replaceable O-ring or similar, or do I have to fork out for a complete valve fo the sake of a 50p seal?

Here's a picture of the leak.
As you can see, it's coming from above the joint where the top section screws into the manifold.
The part number, I'm fairly certain, is 5114718

So I'm thinking maybe my best bet is to buy:

I'm sure there's a dodgy O-ring or a piece of grit in there, but I might struggle to find the right sized O-ring.

The actual seal is inside the top part where the clip fits and cannot be changed on its own.
The complete valve is so relatively cheap that I would recommend that you buy that.
But looking at your picture, the clip seems likely to be badly rusted and you will probably need a new one of them too.
It may be just a little leak to you but you are very lucky that the water has not spoilt the motor unit ( yet ).

Thanks for the advice.

You and your big mouth
Water had indeed got into the motor, and shorted out one of the limit switches. I took it apart, dried it out and gently cleaned the contacts, but the O-ring on the plunger is broken and brittle, so although it's working fine again for the moment I've ordered a replacement.
