Checking Main Vents for leakage
Wondering if...besides STARING and WATCHING ...if there was a way to see if one (or more) of my main vents are leaking steam? The water in the boiler seems to be disappearing a bit. No water hammer. No sagging mains. Boiler is a Slant Fin Galaxy about 8 years old. All rads pitched to supply side. I have had no problems at all up until a week or so ago when I noticed the water was not at its usual level. It is not disappearing enough to set off the LWCO nor the auto fill, but I'm thinking one of the vents in the system may be to blame. The 8 radiators in the house currently have new Gortons installed. The kitchen rad has a Hoffman 1A. I don't see any of the individual rad vents leaking steam, but I am under the impression that they could be without noticing it!
