I have been looking for answer to air in the lines for a while now. I was sure that the water level had dropped in my artesian well. I thought the pump was too near the surface of the water level. As it turns out, I was totally wrong. The problem was that there was a mismatch between my pressure tank and the well. Years ago, my father replaced a steel tank with an inflatable tank, because our pressure tank was not acting properly. It worked great for years. But, then came the problem. Air in the system.

As it turned out, the systems did not match. Apparently, the baffles that were down in the well for the old steel pressure tank had clogged. The new tank worked great, (for years), until it became unclogged, and started to shoot air into the system. The well guy fixed this today.

Hi travland and welcome to The Plumbing Page at AMHD.com. You're responding to a year old dead threads so I gave you one of your own. Please check the date before you post. Thanks

Apparently, the baffles that were down in the well for the old steel pressure tank had clogged And another confusing statement. Who told you all this? Baffles at the well point that match a galvanized pressure tank that won't match a bladder tank? And all this put air in 6the lines? How can that be since a pump system's closed? There's a lot in your post I don't understand but I'm ready to learn. Back to you, Tom

I think you are referring to the bleed valve that allows the wellpipe to fill with air between cycles. When the pump shuts off, the valve lets air in and fills the wellpipe with air. When the pump cuts back on again, it pushes that air into the tank. That's how the old steel tanks were recharged with air. A bladder tank, like you now have, does not need that. He probably just replaced that bleeder valve with a plug.

As SB says, never heard of them referred to as baffles. Oh well.
