were do you attached the bike pump to the expansion vessel so you can fill it with pressure

sharron, March 2010

its at the top of the pressure vessel, so you will probably have to stand on a chair to see it, if you depress the pin and it hisses you probably dont need to pump it up, a can of worms could be opened here because to pump up the vessel you need to open the pressure relief valve and leave it open to pump water out of the expansion vessel, but the relief valves very often drip or totally let by once they have been opened forewarned and all that

Hi, I can assist with this one we had exp. vessel fitted recently. At the end of expansion vessel (opposite pipe fitting) you will find bike valve, remove dust cap and pressurise 0.5 bar(about 7psi) Good luck
