Plumbing Question

Mixer tap in the kitchen,hot water not running. radiator in the bathroom warm at top hot at the bottom (always bleeding).

Do I have an air lock and the system needs to be flushed? All other radiators in the flat ok.

Your kitchen tap may be air locked. Try opening the hot tap, put a cloth over the spout and then slowly open the cold this should push cold main pressure water up the hot tap and clear the air lock, you may get a little wet! And it may take a couple of goes.

Has the radiator always needed bleeding or only after something had been changed on your system?
It could be that your system needs flushing or air could be being drawn into the system.

Have a look at the condition of your water in your f&e or by bleeding some water from some radiator air vents.

the position of your pump or if you have had a new pump fitted for an old one that was fitted on your boiler return can sometimes cause this. Their are other possibilities .

I hope some of this helps

Kind regards

What heating system do you have?

Cold at bottom hot at top, usually sludged up, sludging usually happens on ground floor rads. You could try isolating the valves, take rad into garden and running pressured water through the offending rad, but the best thing of all is to get a powerflush done by a reputable firm. this is a chemical pressure clean, and should sort the problem out, make sure you fill the system with inhibitor afterwards.

If you havent got a combi boiler probably you have a air lock it needs to be investigated.
