[C320-list] CPAP

[David Prudden]

Tom,
I use my older machine (insurance replaces them every 5 years) on board on a 400 watt inverter plugged into the lighter plug with an extension cord to the aft cabin.

When the water got high enough to activate the float switch, it turns on the pump and the water goes down.  However, the switch arm gets caught on the side of the bilge and wont go down, hence the reason the pump stays on.
