       @katieonviolin@sfba.social it's what it says on the top! it's a vent! air being in pipes meant to hold liquid is usually a very bad thing. air cavitation is a big problem in particular.below this is a buffer tank with a float like in the back of a toilet tank that lets air out as it accumulates.
