Piping on one pipe boiler
We have a one pipe boiler system, a Parallel Flow/Up-Feed System and have had problems getting water back to the boiler fast enough. The return water is piped back into the boiler at the same level as the boiler return pipe comes out of the boiler without much of a hartford loop only 2 inches that it comes back up to feed into the boiler. For the right hartford loop it should be looped and tie in two inches below the water line as I have been reading. Is the water line half way up the sight glass or is it the point where the low water cuts off. If it is half way up the sight glass and two inches down if the boiler gets close to low water cut off the incoming water from the hartford loop where it ties into the header could be higher than the water level would that matter.
