Pigtail

Drained boiler today and in the process of cleaning inside, replacing sight glass and putting new pigtail. Does the new pigtail need to have water in the loop when installed or will that take care of itself?

    It will eventually fill with condensation, but I like to put water in there to keep the controls from coming in contact with the steam (even if they might be fine).

    There is no need to fill a pigtail. The first time the boiler runs the steam in the pigtail will condense and fill the pigtail making the required seal.

    I have seen plenty of gauges and pressure controls installed for years with no pigtail and they survive.

    But a pigtail should be installed. And the pigtail must be brass. Steel is a no-no
