Yes, the breaker thats in the cabin panel labelled "water pump" is the fresh water supply. But there is another water pump for the A/C under the cabin entry step. However, I looked at the Formula schematic and the power supply for this A/C water pump comes directly from the A/C unit so there is no separate breaker for it. So just the A/C power breaker needs to be disabled when removing the A/C. And I will cap off the through hull water supply for the A/C as everyone is recommending.

I've stuffed alot of spare parts and other items in that cavernous area now that the A/C is out. Nice increase in storage area.
