Thank you all. Before posting I searched the internet high and low to find this kind of valve, but couldn't. I knew you guys on here would know, and I thank you for the insight. So this is a lockshield/balancing valve. I am crazy and did a power flush of the CH system (ex. boilder) on Friday...

Hi, I have an old radiator in the kitchen next to the fridge, which is understandably off, that I want to make sure is closed at both ends. At one end there is the regulator (wheelhead valve?) so that's fine - that's obviously off. At the other end there is a plastic cap. Under that...

Thanks so much for the advice guys. Yes, there appears to have been some shoddy work done in this bathroom extension. (It was done some time ago.) Have I got this right: Radiators don't need isolation valves fitted because you would always drain the central heating before removing a...

Thank you Tony. That's great news! So a power flush should still be effective.

Sorry, not sure what a twin pipe system means? By cleanse in the first instance, do you mean what we did (fill up with mains, drain, repeat) or do you mean to run the system with a flushing agent for a week or two? My concern with the latter is that the agent might dislodge a load of stuff...

Thanks so much for the quick replies! I think we're before the age of TRVs! A picture paints a thousand words...

Summary: Old/traditional central heating system (had F&E tank) Old boiler was set to gravity as oppose to "fully pumped" (rightly or wrongly I don't know - the system did have a pump as well which seemed to be working at least when the heating was on). New combi boiler installed in a...

Thanks Tony :) That does put me at ease. So then I suppose these are probably the result of settlement or thermal movement? I found this article which briefly outlines the difference between settlement and subsidence (something I was not sure about)...

Thank you. It is a relief to hear more people say it doesn't look like anything serious. The only person I know to be a builder to take a look has (surprisingly) said it is subsidence. I wonder if this is because in Poland the buildings are more solid with deep foundations due to the harsh...

Forgive me, I was wrong, some cracking is visible from the outside at the back of the house. Hope these are ok. The garden is 30m long (not 40-50 sorry). I have posted a picture of the trees - sorry I don't know anything about trees and whether these are the type with big bad...

30 meters away (a bit more if you take the into account angle)

Forgot about these originally. Not sure how significant.
