Radiator problem

[Robbibobbi]

I have a radiator problem.

I have followed everything in the FAQs apart from draining the system and taking off the radiator. I would like to top up the cleaning fluid but I don't have a clue where to put it in the system?? I have checked the TRV and my lockheads are not lockable they turn freely. I have turned off the system and then all the rads but the cold one and then turned the system back on and that hasn't helped.

Also to find the problem for my cold rad I have lifted floor boards and the pipes are cold all the way to the next rad (the cold one is the last one in the system and furthest from the combi boiler). I think having read many of these posts now that it must be sludge in the system, but being a total novice I'm not confident in my prognosis.

Can anyone give me any clues as what to do next?

stop hijacking threads for a start

alternatively don't post things on here before you've read the other posts??

I wasn't trying to hijack I was saving forum space and abuse for posting a new question with another one two spaces below it??

you don't get abuse for posting it

you get abuse for causing confusion when two people are asking different questions on the same thread

What is the sizing of pipe feeding the rads?

Hmm,

I think it is 15mm pipe work but i'm at work now so I can't check untill tonight.

will the pipe size make a difference then?

a) does it really matter to you that much that you have to comment? If it really bothers blankface, that much then I am sorry to him.

b) if you read it, it isn't a different question it is exactly the same, I have just expanded on it a bit.

If you're confident the TRV pin isnt stuck in, try turning off all the other rads, shutting valve on one end will do.

Run heating, you might be lucky and find the obstruction shifts and the far rad gets hot. Once you're satisfied its hot, turn others back on. If the furthest goes cold again afterwards, try balancing the system, look in FAQ's for instructions.
If this doesnt work its either a stubborn air lock or other blockage, rad would probably need to be removed to flush pipes out.

you will find it is frowned upon smartass

yeah I've tried that but no luck. I guess it's time to call in a pro now.

Another part to the problem, the presure just keeps dropping in the system now. Every day it drops from 2bar to 0.2bar?? does this help anyone diagnos the problem??

 

[kevplumb]
