(I have a sealed system Altec 18lt vessel kit working since April 2009)
Today I was letting water out of the system to reduce pressure so that I could take a radiator off and I noticed that the pressure gauge stayed at 1.5 bar and was not going down , I lightly tapped the gauge but still nothing happened I let more water run out then touched the pressure gauge and it jumped to zero. I had presumed the pressure gauge was working ok as it showed 1.5bar but it may have been wrong for some time. When I installed it in april it seemed to be working ok as I had to adjust the pressure up a few times over a week or two.
Any comments on what to do would be appreciated regarding use and reliability of pressure gauge etc?
