Hello,

We are on a small farm and have horrible water that we don't drink. It
buggers and clogs plumbing something terrible.

A couple of years ago, we decided to go the fiberglass pressure tank route
as we got tired of rusting issues. The local well and pump guy came out and,
despite my reservations, installed one that has a vent gizmo on top instead
of my usual draining every few months after waterlogging. My concern was it
would plug up... after about 2 months, it did. He then added another gizmo
in front of the tank that is the device in question:

it is about 10 inches long, has what looks like a tire valve sticking up
from it and is supposed to suck a little air into the tank every time it
runs... and it does that well (never have waterlogged since). My concern
with this item was that it has, according to him, a 3/8 orifice inside that
hurt my flow very badly. Now that this thing has had time to gunk up a bit
(everything always does) the flow is now almost unacceptable. Relations with
this guy deteriorated long ago and I'm about to scream uncle and tackle
things myself as I always used to do before him.

What is this thing called?
Can it be taken apart to clean?
He mentioned that there was another version with a larger diameter innard...
I'm wondering about swapping it since I need to do something anyhow... does
it allow more air proportionally? I do not like the idea of even more air in
my tank as I wish there were more drawdown than there is now.

Does anyone know anything about this gizmo?




thanks
