- if the boat was submerging switch off the pump
- if need surfacing then switch on the pump to surface
- during submerging or surfacing WSW1 is OFF and WSW2 is ON

It's not clear to me whether WSW1/2 are simply switches or whether they are valves.
It seems to me that without some kind of valve, your MBT will lose air when submerged, and result in completely full MBTs. Was that the intent ?
I would suggest removing the water sensing switches and keep the system simple.
Try the bladder system
