I have two zones boardboard heating with a propane boiler. I noticed today, heavy corrosion on one of the two drain valves.
My first photo shows two circles. The top circle is where the corrosion is and the bottom circle is where the corrosion is dripping down onto. The top circle area is oppposite/across from the circulation pumps. The second picture is a closer view on the area.
Can anyone tell me what the most likely cause of the corrosion is and what I should do about it? My system is five years old but I think this only became a problem over the last year (I could be mistaken).
thanks!
