Top floor radiators not working.

[robocat]

Hey there guys .
Had a new pump installed a few weeks ago. Now none of the rad`s upstairs are working. Thinking either that it could be air block but drainmed air from all but one of the rads, the other is one that we cant due to not being able to get rad key bolt out . or expansion tank not filling system, but i cant find it in loft , any ideas.?

What boiler have you got, make and model?

Have you got a sealed system?

 

[bengasman]

did they all work when the plumber left?

No but he thinks is was a air / sludge block , he has come over to look at it and see if he can sort it but to no avail... He is a mate so cant be too hard on him . He fitted an identical pump to one that was replaced as it was making a grinding noise, bearing me thinks or something,

Ideal Mexico is the boiler make, if u need more dettailed model id ill get it.

Been looking at some books and web site and some of it points to lack of water in system , but the expansion tank should take care of that , but there is not one is the loft ...

If you have no expansion tank, you may have a sealed system.

Can't remember if the Mexico's can be put on a sealed system or not

Do you have a large red vessel anywhere?

If so, it is sealed and chances are the pressure needs topping up.

cheers , the actual Model is a Mexico super 3 Gas boiler. Sounds i hope like the likely cause but in the loft the expansion tank is not present . Thats the twist .. any idea on that one ?

Sorry Just seen this, large red vessel as in tank?

If the pressure needs topping up would that have happend when the new pump was fitted as in the pressure being lost . ?
