Logic 30 combi low water pressure

[jaynee121]

Hi,

I have a Logic 30 Combi boiler and the water pressure is low, can anyone help me with topping it up, on the lest under the boiler is the gauge and on the right are four taps two blue and two black, which ones do I turn to increase the pressure. thankyou

The two towards the front of the boiler, one black one blue. They should be joined by a silver flexible hose, if not it needs to be attached for filling. Aim for 1bar on the gauge

as scott says. the blue and black should be the closest ones to you as you are facing the boiler. Joined with braided hose. listen to scott and you'll be ok

Depends how old the boiler is I think they changed the colour round a few times, but like they said it's the two closest to the front
