My water system in my house has many components. I'm n a well and have the pressure tank, then a culligan iron filter, and the a water softener. Lately I've been getting a lot of air in my water. When I run a back flush on the iron filter (the first component after the pressure tank), it seems like every time the pressure tank kicks on it sounds like air is pushed through the line. I can hear an air sound at the iron filter. Would an issue with the pressure tank cause that?

You need a new Air Volume Contol or AVC. It is screwed into the side of the tank about half way up.

Then you probably have a hole in the pipe below an above ground check valve that should not be there.

Jreed,
With your description of the symptoms, I initially want to suspect the air injection system on your iron filter. Most iron filters require oxygen (or atmospheric air) to be injected into the system so that the iron filtration media can operate to full potential. Basically, you need ferrous iron, oxygen and a catalyst to convert the ferrous iron to ferric iron which can be filtered out.
If your well water has too low of a concentration of dissolved oxygen, you have to inject oxygen into the system to make the catalyst work to oxidize the iron into a filterable form. So these iron filters purposely pump AIR into the water.
If the air pump is stuck on, the valve is stuck wide open or there is a break in the tubing or piping, you may be injecting or sucking huge volumes of air into the system. Much, much more than is required. This would be the area that I would start to investigate first as it is purposely designed to pump air into your water system.

Check these, particularly the first one:

It may also be worth considering a new system. Culligan units are not cheap to buy, but I think they may not be so cheap to get repaired either. Maybe repair would be reasonable.

As it turns out, I was checking the air injection check valve instead of the air relief solenoid. I pulled the air relief solenoid off and cleaned and that seem to do the trick.
One more question, I have a culligan medalist that seemed to lose a fair amount of resin through the backwash a few days ago. Could that have something to do with excess air as well? It is only coming out of the drain hose and not getting into my plumbing.

Jreed,
I cannot answer to your question regarding the resin media in the post just above. However, I would like to spur you on to consider a B.I.R.M. iron removal filtration system. I read some of your other posts in the thread links up above and thought I would at least try to inform you of another iron (an manganese) removal process that may help you reduce operation costs. If I read everything correctly, you are using an iron removal system that requires rejuvenation with a brine of some sort. If this is correct, I would like to tell you about B.I.R.M.
BIRM is a natural mineral that is coated with a catalyst. This mineral, with its catalyst coating, reacts with the ferrous iron (the type of iron that is dissolved in many wells) and the dissolved oxygen in the water to form ferric iron.
The ferrous iron cannot be removed from the water by mechanical filtration. It has to be converted to ferric iron first in order for it to be removed by a filter mechanism. The BIRM media (and its catalyst coating) and the dissolved oxygen perform this conversion process.
That beneficial process is not the end of the BIRM media's duty, however. Once the ferrous iron has been oxidized to ferric iron, the BIRM media actually serves as the mechanical filter to trap that iron within the media.
To remove the buildup of the ferric iron, you simply backwash the BIRM with water straight from the well. No sodium chloride, no sodium hydroxide, no potassium permanganate, no chemicals required what-so-ever. Only vigorous backwashing with fresh water is all that is required.
To top this advantage, the BIRM and its catalyst coating is never depleted unless it is fouled by chlorine or some other agent. It will virtually last forever (within reason).
If this idea interests you, check out B.I.R.M. with Google. I use it! My friends who have iron water troubles use it! I swear to you, it works really great! It is not too expensive and you can build your own DIY filter mechanism for it or you can convert a discarded water softener to put it in. If the mechanics and electronics of the softener still operate, you are home free! Just dump out the used water softener resin beads and refill it with BIRM!

I think jreed's system, like mine, may use Centaur Carbon. Mine works well for me, and works for H2S.
