why is there lots of water coming from my boiler overflow?

The Baxi Solo 2 doesn't have a prv!

Make sure the ball valve is ok in the f&e tank. If it's failed you will get water coming out of your o/flow.

If it only does it when the boiler operates try turning down the potentiometer setting on the front of the boiler. It's a small black knob numbered 0 - 6. Also lower down your pump speed.

Make sure all your radiators are full. Hopefully it's just the ball valve.
