hi guys - i have a grohe adagio concealed flush fitted and water pressure is mains fed - there is a restrictor in it but takes ages to refill so i removed the restrictor and it fills really quick but right at the end of the fill there is a slam /thump in the cistern - is there any way to stop...
i usually just put the switch to off ( no hot water or heating ) position for a couple of mins and that cures it then it might run for weeks ok then do the same again - im just worried that it does it when we are out of house
my 15yr old vokera linea 24 switches the heating on whilst in water only mode and radiators get very very hot error code says co the boiler can run for weeks and then does it once and runs ok for maybe a month or so then does it again - any ideas ?? - thanks
