One for the plumbers:
We've got a radiator (upstairs bathroom) that keeps oscillating between working normally and barely getting warm - for several days at a time. Rad is brand new, valves are new and confirmed working. Plumber thinks there may be some kind of blockage in a pipe that is building up, releasing, build up again etc. He's not sure where though. The old rad worked fine for most of its life then started doing the same after the valves were changed to thermostatic ones hence we got the rad changed. We've also had the valves swapped again just to make sure it's not those either.
I'm not sure what our options are and what the best course of action is.
Should we just get the system power flushed, and is that the right thing to do? Am I right in understanding it's just shoving water through at high pressure? Any risks to that eg bursting joints, resulting leaks etc? Are there any alternate steps we could/should take?
