Just doublechecked the nut on the feed pipe doesnt have any line - the plastic key fell off long time ago, so we marked the nurt and above it so we knew where it should bé. Will try taking it off in. Morning
thanks for your help, will have a good look again in the morning, too late to do it now, hope we can get it sorted, not a great time for no heating.
will let you know how we get on
have taken pics of the boiler and uploaded them to see if they help.
not sure how to put them so you can see but have clicked 'show my images' presume thats it
thanks for that, yes we have turned the water on and off, (the plastic thing fell off a good while ago.
is it best to take the water on the highest radiator (thinking of any air in syetem) or the lowest one (which we have been doing with no effect) will go take a pic in a minute
On one side of the loop is a hex. shaped nut and on the other is the nut to add water (it did have a blue plastic thing on it but it snapped off a cple of years ago.) so is it simple to remove? am normaly okay with ordinary pluming like fitting bathroom suite or sink it just i dont always know...
we have a worcestor combi boiler it says s25i on the casing but isnt the one that comes when i google it.
always worked fine, if we switch it on it working okay now.
the pressure dropped to below 0.5 so we did what we did before when it has happened we added water with the filler pipe whih...
