boiler pressure
Discussion
Worcester boiler was running a bit low on pressure, under half a bar, so I let some water into the system. The pressure gauge was a bit behind in recording the extra water so I ended up letting a bit too much water in. Now it's reading between 1.5 and 2 bar. It's a steady reading well short of the red zone which starts at around 4 bar and it doesn't appear to be going up any more. Just wondering if there is any way of lowering the pressure once you've got to this point as i know 1 bar is the optimum.
You don't want the Pressure Relief Valve to operate though, debris can get stuck on the valve seat and it won't seal properly.
To removes excess pressure you can bleed the rads or open a drain off valve. Some of the older Worcesters have white drain off valves on the underside of the boiler.
They don't always work, so if you don't get water after a couple of turns! Don't turn anymore! You may get wet (talking from experience)

OK thanks, I guess I'm just being a bit paranoid, for future reference though is there any way of reducing excess pressure when all the rads are OK and not needing bleeding?
Just open a radiator bleed valve and drain off some of the water. This will reduce the pressure.Gassing Station | Homes, Gardens and DIY | Top of Page | What's New | My Stuff
