Weil-MClain EG-55 - unknown device - hissing sound
After running my EG-55 for about an hour, I start to get a hissing sound from the device attached below. Should it behave this way. It's appears to be
a vintage piece, should it be replaced? There is only one of them and its connected to a pipe running to the boiler and the steam pipes leading to the raidators. It looks like some sort of relief device. Advice please. Thanks.
