Hi,

According to the manual my combi boiler has 3 speed settings. I recently moved into this house and the downstairs rads have a hissing sound which seems to be related to a high flowrate. It’s more a nuisance than anything else as the rads are fine.

I would like to adjust the speed downwards but does this need an RGI technician or can I do it as the front cover must be removed to access the pump??
