Good Evening,
Hope someone may be able to help. My girlfriend has a Potterton Apollo 30 boiler in the house she rents. Her son has over pressurised the boiler so it now reads at 3.5 bar. Can anyone tell me how to release the pressure or do we need to contact the landlord to get a plumber out. Hoping someone can help. Kind Regards Stuart

Hi Stu. You should be able to locate a BOILER DRAIN at the bottom of the boiler. Simply attach a hose and open it until pressure returns to a more normal 1.0 bar...

It should be that simple... *crossing fingers*!
