Hi, i've checked the filter on the return valve and it is spotless. I haven't removed the valve to check it's fully open but it is clearly in the open position. Was the valve in your pic broken?
I will check this on mine asap.
Thanks

Hi That quote was not from me I definitely do not have any valves or a hot water cylinder.
I have been tinkering with the balancing again and have managed to get some heat to another rad. I think that's about as far as it will go though because if I shut down the hot rads any further they just...
I have tried balancing but even if I shut down the valves on the hottest upstairs rads I am barely getting any heat downstairs with the valves fully open. It's not microbore. I had 3 old rads downstairs that were on microbore but I replaced these and used 15mm. This is why I'm wondering wether...
Further to my posts of a few weeks ago. I have now had my system power flushed. It did wash out a lot of crap but it has made no difference at all. Got the engineer back in from heat team who has now fitted a new pump Still no difference! If the upstairs rads are on the downstairs ones are cold...
I have the engineer coming out again Tuesday. I'll try to persuade him to try a new pump. If he won't I'll buy one myself and give it a try,
Thanks for the advise I'll let you know how it goes.

Thanks Bamber. I know it's a big house but we are in Hartlepool where you can buy a house for what most people spend on thier cars. I'd love you to come and fit a new pump but aren't you in the states?
Thanks softus. There is only one rad on the top floor ( attic Bedroom) and this has been run off the 15mm pipework in one of the 2nd floor bedrooms so I don't think it condtitutes a third system.
Is there any way I can test the pump efficiancy?
I have 13 rads the furthest one is about 15 metres away the boiler output is 31k. It is a 4 bed 3 reception 2 bathroom house over 3 floors.
Hope this helps
Cheers
Pete
There is no bypass valve on my system automatic or otherwise.
The boiler fires up for about a minute each time and all the teperature lights come on so it is getting hot.
Thanks Softus. When I did the flushing I did have all the valves closed.
I do have a digital camera but no airing cupboard. What did you have in mind?
By the way some possibly inportant info I haven't given yet is that if I now shut off all the upstairs rads I can get most of the downstairs...
Sorry if I haven't been clear. I have not replaced all the rads and pipework. I had 3 big old rads with microbore pipes downstairs. I replaced these only and changed the pipework to 15mm. The rest of the house was updated about 4 years ago I'm guessing because that is the age of the boiler.
As...
I haven't tested the pump at all this was done by the engineer who came out on thursday. He assured me the pump was fine and showed me the needle flicking up as confirmation.
Can the power of a pump fade as it gets older or is it simply a case of working or not working.
As for the airlock I...
