I've searched the forum for this problem and could find nothing of a similar nature.
I have a Vokera 12-48 rse boiler and when i turn water on to it so it has pressure (1-1.5 bar), it causes water to flow into the water tank through one of the water feed pipes at the bottom. This is causing the overflow pipe to run constantly, and is causing a small leak on the side of the tank itself where the overflow exits the tank.
Is there any common problems that would cause this to happen?
I am unfamiliar with plumbing, so thanks for any advice.
