New radiators in loft using microbore system

[percyt]

Background:
- have an old 10mm microbore system
- have brand new combi-boiler
- have just had our loft converted and have 2 new radiators in it
- new radiators have been linked to radiator in room on 1st floor

Problem:
- The 2 new radiators in the loft and the radiator that they are linked to are not working. There wasn't a problem with the 1st floor radiator before.

Help much appreciated.

How are they linked to the old rad? A diagram or pic. may be easier. If they have been linked wrongly, it may cause problems. Should ideally be linked back to the manifold.

Are all the valves turned on?

Try turning all the rads off in house, then open one of the problem rads at a time with heating on. See if it pushes airlock or blockage through.

Just uploaded a pic hope this works !

Copper pipes are flow & return to the rad in the bedroom, the grey ones are the ones going up to the loft. View media item 36677

Ok thanks - daft question but how do we know where the manifolds are?!

you need to trace those copper pipes back from the rad - past those tees -there will be a mainifold . Whoever did that lash up has no right to call themselves a plumber - hang on this is little britain , and anyone can call themselves a plumber It`s just gas that is regulated
