More On FOB Issues

Continuing with FOB operational issues :
Many times calls are made with the following complaint.
Why does the float keep dropping when the keg is not empty

Lets start with a keg in service ( not full & not quite empty )...
This issue can be caused by.
leaking seal on keg or coupler, over carbonation from high gas pressure on keg, warm keg and or cooler are most common causes.
New Keg change and float drops:

If when changing a keg this occurs, follow these steps.
Flip bottom lever up. Wait for line pressure to equalize ( you will see the flow stop )vent the air from float cup. Make sure to check the jump line from the keg is clear of air from keg to FOB.
Once this has been done & float has risen flip lever down.
Any on going float drop on a new keg that is properly set is a sign more often then not of a bad seal or keg flow problem which can include a stuck check valve in the coupler.
