Water Well Expansion Tank Waterlogged

[Mississippi_Joe_39565]

ISSUES

The expansion tank became waterlogged and caused frequent cycling of the pump and the water odor was very noticeable.

* The AVC tubing is currently connected to the Water Pressure Switch instead of the AVC Port on the MSE-7 Pump.

* The Pump Pressure Regulator port that the Water Pressure Switch tubing was supposed to connect to was plugged.

* I don't understand why a Mazzei Air Injector was installed?

The air injector is probably plugged as well. The air injector is what will keep the tank from getting waterlogged and keeps the water from having the rotten egg smell. You probably need to clean the air injector often. The pressure switch does need to be connected after the air injector, so at the top of the AVC is fine.

There are other ways to treat the water for the sulfur smell, but the way you are doing it is probably the simplest. Just need to make sure the air injector is always injecting air or the tank gets waterlogged with smelly water.

Thank you for your reply.

The Mazzei Air Injector might be the simplest way to go but doesn't it restrict the water flow too much? Going from 1" pipe to maybe less than 1/2"?

What about the Expansion tank float valve not working properly. It is labeled Invensys 0718D and I cannot find out anything about it online.

If you need more volume. you just need more pump. An ideal aeration tank solution utilizes a second pump inside a non-pressurized tank. Second to that is a snifter/bleeder/check air-maker but it requires an AVC.

It wouldn't make any difference that the AVC doesn't work if it is plumbed to the pressure switch. AVCs are a throw-away item, not field repaired.

It wouldn't matter how much water can squirt the air injector if it was going to a storage tank with a boost pump like LL mentioned. Putting the air injector on the line coming into the storage tank is would look like this except with a jet pump instead of a submersible. also, it is ok to plumb the pressure switch or a gauge to the top side of the AVC, as the excess air is still released from the bottom port on the AVC.
