If that was me, there'd be another follow-up thread asking about how to deal with catastrophic water leaks!
Well done!

well ive just checked the joints and all seems fine so far 🙂
now that i'm satisfied that its not leaking, i need to put some rust inhibitor or somethings in. we didnt do it monday in case it needed draining again and we'd have to buy more.
so, what would you recommend? one of the fernox jobbies (if so which number?), or another of my mates said he used MC1 or somethings.
thanks
I'd have still waiting until summer.
Have you had to rebalance the system? That's always felt like the black art to me - a simple rad swap is easy, break anything though and you need a plumber (or someone with skills) and avoiding breaking things (like kinking pipes when you discover that its way heavier than it looks!) is also where experience comes in.
Any of the kits will be fine, usually it's a flush then refill with inhibitor. Think I used MC1 or whatever it's called. One of them comes with a spout to add the contents to the rad which is handy if you don't have a filter to dump them into.

no, dont know how to do this. my mate touched on it but said he was also a bit confused by it too so i need to read up on it.
i know you do it by turning that little knob/screw at the bottom to control the flow of water through it, but not exactly sure what im looking for.
for instance, once the rads were up, and the CH turned on, we felt the radiators, they felt fine/hot, but on touching the 2 pipes, one was hot, one cold still. and that was after 1 full turn of the screw. i didnt know what i was doing but opened it fully and it started gurgling a bit (water now coming through i suppose) and then became hot.
but i dont know why it was still cold with a full turn (yet the rad was hot), and i needed to open it fully.

well ive finally got round to finishing it (i hope), by putting the fernox in.
however, i just wanted to run it by you to make sure ive done it right?
as it stood, i had 2 rads changed, and whatever fernox was still in the system that hadnt been drained (i only drained the two rads that i was changing). so now i needed to empty enough water out of one radiator to put in some new fernox.
i used the bathroom towel radiator as it had a vertical bleed screw and nut, so easier to fill. i put a drain from the bottom out the front door and opened up the little screw at the bottom until water came out. i then thought that as a load had come out id have emptied enough to refill with fernox. but..... everytime i cracked the bleed screw water came out so obviously not.
scratchy head time, and common sense told me that every bit of water above this height in all of the pipes in the loft was still pushing down on it, so i had to isolate that one rad so it only emptied itself if that makes sense.
closed the isolation valve on the other side,and the little screw under the plastic cap (i guess they both do the same thing but not every rad has an isolation valve maybe?) and then opened it up again at the bottom. hmmmm....water still to the top of the rad, and nowt coming out the drain. scratchy head time again. must be the TRV. so i opened that fully and yep, out came the water. emptied a bottle of fernox in (after closing the drain of course).
opened the isolation valve and put the boiler pressure up to 1 bar again. i then went round every radiator in the house bleeding them. only one of them had a bit of air in, but bled that and now all the rads are full of water and no air (hopefully).
re-pressurised boiler to 1 bar again.
and thats it.
learning points are to isolate the radiator that youre draining first, or you lose too much water and itd take ages. oh and open the TRV or else it wont drain.
everything sound present and correct?
thanks for all of your help.
