Hi,
I am a homeowner, I had a new unvented cylinder (OSO DC 300) fitted in August, and had a small problem yesterday with the pressure valve dumping water and making a lot of noise. Eventually this was resolved. However, during my conversations with plumbers it appears that I have a red expansion vessel rather than a white or blue one!.
On investigation, it appears that although my cylinder came with a white one, my gas safe heating engineer saw fit to install a different one.
Is this a problem I should have fixed? My 'google' research suggests that the difference is that the red ones are not potable. I am not sure how much of a problem this is.
