I have a saunier duval isofast condens f35e boiler. Over the winter it has continually dropped pressure from 1bar to 0.7 in about 5 days.
There is water coming out of the pressure relief outlet when the central heating is on.
I tested to see if there was air in the 10ltr expansion vessel and water came out instantly and then dripped followed by a little bubbling water.
Does this mean the expansion vessel is knackered or can it be re pressurised? If it is knackered is it an easy enough job for a diy-er?
Cheers
