Water drain line pours out water when pump is on

[drive805]

96 holiday rambler endeavor....Last few times out camping noticed we went through water fast (boondocking)
Upon inspection, i found water is dripping out of drain line. Opened line and with pump on water pours out.
Replaced water pump about 2 years ago .
Can someone give me an area to start?
Bad check valve?
Bad pump?
Leaking ? Any help would be appreciated thanks

Sounds like the water drain line valve isn't closing completely.

Replace valve maybe?

Closed valve....shouldn't leak if it is GOOD

Replace the valve

**Valve open/pump on...water should blow out as it is under pump pressure
Hook up City Water...same thing would happen
