Honeywell V4073A Valve and 3 way port

[seco services]

Have you a larger pic showing the valve and pipework ?

 

[Dan Robinson]

You should have a two port valve as well seeing as you have an unvented cylinder.

Or do you want to see something other than the two pictures I've posted?

 

[Dan Robinson]

Yes.

Yes i've done that but want to see more of the pipework around the valve area.
I can see the rad side go's down, thats it.

I still think you have an airlock around the valve.
I'd be inclined to slacken a valve nut to release any air if any.

I have these images as well? Any use?

Sorry, I was taking these and uploading while you replied.

Hang on- I'll go and take some more

Looking at the valve both pipes to cyl/rads come out and go downwards.
you have no where for air to escape.

 

[breadnbutter]

you could have a blocked cold feed, (not enough water in the system), do you have any manual vents in the airing cupboard (thumb vents)??

Not sure about the thumb vents. How would I tell?

Thumbscrew vent.

hate them things,always blockup,leak,thumb screw more like stillsons

That pump looks like a cheap and nasty one - how are you sure it is working?

Where is the two-port valve for the cylinder?

 

[Boynielaad]

Sorry about the pump

Not sure whether there's a 2 port valve - things are pretty tight in there!


I have, as suggested, loosened the nuts around the T valve and some air did escape. I now have very hot water flowing from both sides of the valve although, as yet, I have no warmth in any of the rads - suggest that's a daytime job along with balancing the system and bleeding the rads.

Thanks for all your help and suggestions so far today

"how are you sure it is working?"

When I put my hand around it I can feel the blades whirring around inside and can hear the water being pushed along the pipes.

The water is also now flowing reasonably well

check your nearest rad it should be getting warm by now.
