My Greenstar 28i junior pressure is wobbly?
Hi,
The pressure on the gauge keeps dropping below the green area every day, but when the heating is on it suddenly shoots up to the red side 3/4. We have checked for leaks and can't find any anywhere it is only 4 years old and we have already had some problems with it please can someone advise us as their helpline isn't much use.
Many thanks
Mandy
