Recently we noticed a leak from our boiler outside from the Pressure Relief Valve outlet pipe, the part is now on order. However whilst we are waiting for this we noticed that the pressure on the boiler keeps dropping to 0.5bar and the boiler clicks off. Then whilst the heating is on the pressure goes up to 4bar and we have to release the pressure manually.
Does anyone have any suggestions as to why the pressure could go up and down on it's own?
Thanks
