Allowed me to easily add an air vent to my 50 year old system that does not have one. I had previously purchased a Resideo FV180A air vent which I intended to add in as a bigger project. However, when I found this Webstone manifold that allowed me to simply stick it where the relief valve was, it facilitated things enormously. AI said that the FV180A was better than the Webstone air vent included, so I purchased a 1/4" x 1/8" NPT reducer, replaced the Webstone air vent and will keep it on the shelf as a spare. It was a beautiful sound while refilling the system and hearing the air being purged through the vent.
I also added a Webstone Pro-Pal Add-A-Drain in the port under the air vent for convenience.

Great Item For Wall Hung Boilers
Used this item on a boiler installed by others to add a low water cut off and air eliminator. Just remove the existing relief valve, install this device and reinstall the relief valve.
