help new Mid Position Valve is it faulty???
british gas just replaced the valve resulting in no hot water (hot rads), I call them again the next day they come out he said everything is ok but valve might be sticking because of sludge??? and recomends that he powerflush the system at a cost of £600,
I call them again but this time they say they will not come out untill i agree to the powerflush (sounds like blackmail to me) Anyway ive tried all switch combinations on the programmer but the valve will not move back to position a (hot water) the only way it will move is to disconnect the grey wire and then it freely moves to position a (without any sludge slowing it),any ideas would be very welcome.
