Been to a Glowworm betacom today less than 2 years old and glowworm will not cover it.
They said it was sludged up and that it had not been installed correctly ..
To be honest it all look ok to me . I flushed it and fitted a boiler buddy .
Plumber that fitted it would not come back to it ..
If you had to flush it and install a filter, it looks like GW were right.
I flushed it because thats what the customer wanted but to be honest it didnt look to bad to me.
