I have searched Google and looked through the manual of the unit and can find not reason for the following... Several months ago a friend had a new Bradford White water heater installed. Today she noticed a slow but steady stream of water(which is hot) the width of a "drip" started from the pressure release that is plumbed through the wall to the outside. I looked at it and manually released the pressure using the rocker valve on top of the unit and was able to get a "gush" of water to flow. The drip continues albeit a bit more slowly.
What would cause this? The unit was installed by a professional plumber referred by a home warranty. Anything to worry about?
Thanks
