Water drainIng from pump

[carol108]

2015 Sunseeker. About to take a trip and put 1/3 of a tank in fresh water. Ran the toilet a little and shut pump off. Went outside and water was draining out the tube connected to the pump that I use to put antifreeze in.
Anyone know what the problem might be? I’ve seen the problem with being hooked to city water and the fresh water tank filling up and it’s the relief valve on the pump, but never heard of this. Any help appreciated.

There should be a valve in the antifreeze line. That needs to be off (handle 90 degrees to the antifreeze suction line).

Valve isn't completely closed or has failed.
