I have an oil fired boiler and there is an expansion tank next to it. I regularly have to top up the pressure in the expansion tank by opening the water inlet valve but everything seems to work OK (it seems to drop regularly to about 1 bar when cold and I top it up to 1.5 bar when cold). But someone told me to check the schrader valve to see if it leaks air or water - but when I release the schrader valve nothing seems to come out (even when the pressure guage, which is attached to the relief valve and the water inlet, reads 1.5 bar) so I am wondering if there is something wrong? I have also read about recharging the air in the expansion tank but don't know whether this is something I ought to be doing (and if so how to do it)?
