Radiator Service Valves Leakage? Help!
I have a single pipe steam system. Installed new Burnham boiler last wk, with a gallon meter on the auto feed.
It is using 1 gallon of water per week, based on the auto feed meter.
System has 15 radiators. 14 have service valves (1 doesn't). 12 of the service valves appear to be original--probably at least 80 years old--none have any visible sign of moisture leak. All are fully open, and seem to work in terms of being able to turn handle on/off.
Of the 15 radiators, 12 have new speed vents--3 have original vents. The main vents are newish (<3 years)
All piping, supply and return is visible and not buried--a very short length for one radiator exits crawl space, and can't be seen--but it is only about 3 feet from exit to radiator, so it seems unlikely to me it is buried.
So, given 1 gallon/wk loss, and 15 radiators--the average loss per radiator is 1.3 ounces every 24 hours--does this amount of leaking strike you as being caused by bad radiator service valves?
Or, is that amount of loss indicative of a pipe leak or other type of leak? Again, I see no visible leaking on walls, ceiling, or where the supply/return pipes are visible in basement.
I prefer to troubleshoot intelligently, rather than just replacing parts and hoping--but i have zero experience here--so it would help me alot from anyone who has seen this before--particularly if service valves were the leak culprit
