HR92 noisy after 3 years
One of my HR92s that’s in the hallway has suddenly turned noisy when opening and closing. Do they just wear out after time? I have tried switching the heads and it’s the same. Havent tried changing the part that sits on the pin yet.

What do you mean by "switching the heads" - do you mean swapping the entire HR92 ?Originally Posted by Tigermad
If so it can't be a faulty HR92 if another HR92 in the same place is also just as noisy.
I agree with the suggestion to check the valve pin isn't seizing up. I've had that happen to me with some cheaper TRV valve bodies after about 2 years and I ended up replacing them with something better.
A squirt of WD40 into/around the pin works wonders too.
