[hypoxia]

I finally got back to this problem and added a Hella Delay Relay 5HE996.152.15 to the Auto Water Fill.  I'm starting with a 10 second delay, it seems to have cured the problem of the water tank Madison M8700 float switch turning the Asco Red Hat fill valve on & off rapidly due to sloshing when the tank is nearly full.  That seems to cause the Madison M8700 float reed switch contacts to burn out as well as adding a lot of wear on the Asco Red Hat fill valve.  It also caused the tank to overfill. Now when the Madison M8700 float valve switches off and the sloshing causes it to switch on, the Hella delay relay adds another 10 seconds before it turns the Asco Red Hat water valve on.  Since the sloshing keeps cycling the switch, the delay relay won't turn the water valve on again until the water calms down, sometimes 60-90 seconds later.
