I have looked around the wiki and forums but do not see a specific answer I am looking for. Forgive me if it is already out there.
The distant radiators at the ends of the two branches of my system are struggling to get heat. Don't believe it is sludge etc as the water was clear a couple of months ago and has sentinel in it. Used to work ok and my gut feeling is that the pump no longer seems to have the force it used to have.
Can this happen to a pump? Clearly it would be easier if it just stopped working altogether.
System is Y-plan and the water circuit functions without issue. Have shut down all rads and then turned on one radiator at a time. They do all then emit heat at a very hot temperature but after what seems a long time given I now have the pump on speed three. When it was installed (9 years) you could never use speed three as it was too fast/noisy.
