My bi-folds have been in for about 8 years and the bottom corner of the traffic door has been catching for about a year. It seems like the door has dropped a little so i need to adjust it, problem is i cant seem to find any way to actually adjust the door! The hinges do not appear to have any...

OK thanks for the tip - i see what you mean. I'll order one in.

Perfectly confident - Its just they look a bit seized up having been in there for many decades. I guess i just need to give it a go.

Is there a particular reason a TRV body is not made to fit onto the larger diameter tail? These radiators are old imperial units and i am not convinced i'd be able to get the tail out, they have been in for a while!!! Ideally i'd swap the rads too but they are in decent enough condition and the...

thanks for that although i'd rather avoid swapping the tails if thats possible with a different TRV? I dont understand why a drain off valve of 15mm / 1/2 inch is different to the same TRV?

I am installing a drain down valve, as i dont have one, in my open vented CH system and at the same time taking each radiator off and giving them a good flush. I recently took one off for decoration and the amount of thick black sludge that i flushed out the bottom was alarming to say the least...

interestingly ..... I was at the F&E tank looking at the vent so that i could bung it while the hot water was on but the CH was off and water was being pumped over the vent constantly. Does anyone know where to look for what could be causing this? I googled around and i hear mention of a...

With regard the installation, it looks a touch agricultural to me for sure but alas this was deemed acceptable to the guy who installed the system. The pump is on the ground floor and so circulating over 3 floors which makes me think perhaps a greater head is needed. The radiators have been...

I did wonder if the vent question would generate some Lolz but thanks for educating me. here are a couple of pics of the valves that also need replacing. As I said sometimes it gets noisy and others it just seems to lack efficient circulation hence me wanting to swap it out and see where I am at.

Any clues where the vent may live?

Can you elaborate on that please ?

Yes, the gate valves are knackered and need replacing along with the pump. To replace the gate valves I need to drain the system yes? Will post a pic later

Ok when I get home I will. The main reason I want to replace the pump is that I don’t think it’s working correctly or consistently moving enough water. sometimes the heating works perfectly and others some of the radiators take an age to get hot. No amount of bleeding or balancing helps and...

Hi - I need to drain my central heating to replace the pump, it’s an open vented system, but as the gate valves are also corroded it’s a full system drain first. I do not have a drain valve that I can find but I do have a downstairs radiator, by a door, that has this - if I undid this bolt and...

Not difficult for me to understand, just that when all the information i get from 'guides' mentions that the lockshield is the return then i guess i understood there was a reason for that. I of course understand that a radiator just works by water flowing through it, and so direction should not...
