Hot water trickle


Recently all hot water taps in my house started running to a trickle after about half a minute. We are in a soft water area - no scale in kettles, around taps etc. I have back flushed the system by connecting the cold tap to the hot and opening them both until the tank overflowed. I have run out of ideas. Anyone know what else I can try.
Thanks

My guess would be a blockage in the pipe from the header tank to the bottom of the hot water cylinder.

John. I had a similar problem about six months ago. it was a piece of the hot water cylinder lagging foam that must have been floating around inside the cylinder since its manufacture. And hey presto! one day it decides to enter the outlet pipe and get stuck sideways across a badly corroded 3/4" old Tee joint. all the taps were reduced to a dribble. Luckily I knew the joint was corroded and decided to change it anyways, cannot really see how water was getting through it as with the corrosion inside there was only about 1/8" hole through the centre. Hope you do not have the same problem. Regards and good luck. Len.

Newly-bought old flat, hot water supplied at reasonable rate to bath and kitchen sink taps, but supply to wash-hand basin hot tap a tiny trickle. Any ideas on this variation, please?
TIA, Bill
