In Reply to: Sudden Pressure Loss Baxi boiler posted by Mike Conroy on November 13, 2008 at 05:23:13:
Today I've actually seen what happens before the loss of pressure.
The indicator lights on the boiler were showing the water temperature at 60° but no hot water came out of the tap. Nor did the boiler fire up. I let the hot tap run a while but only got cold water.
I left it a while & tried again, this time watching the boiler. This time when I turned on the hot tap the DHW sensor warning light flashed on then
off, the boiler fired up and the water pressure dropped from 2.5 to 1.0 (it now stands at 0.5).
Can you help?
Could there be some way that the water in the primary circuit is leeching into the DHW and causing the loss of pressure?
