I have been told by British Gas when they replaced the pump that the central heating system could do with being flushed out and quoted £845 to do so. Is this worthwhile? Does anyone know what is involved and is it possible to DIY? many thanks
The drayton TRV 4valve I have purchased has a 15mm connnector to the rad. The rad however has an existing connector which is 3/4 If I try and remove this existing connector I am afraid that it may break. Is there a way to keep the existing rad connecotr in place and connect to a Drayton valve...
