Boiler/baseboard valve corrosion

[wormwood1978]

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!

Looks like a simple leak. Remove shut-off valve, apply sealant to threads then reinstall.

yup. a leak . find out where it's leaking and fix it. hard to tell from the pic where the leak is , but it appears coming from the connection at the drain valve

its a leak remove it-- clean it-- tape it--and put thread sealant on it I prefer rectoseal #5
