Winterized RV & now pump wont stop running

[Oldmso54]

Winterized RV by blowing out lines w/air compressor <40 psi. All was well for about 30 minutes and then the water pump (pretty sure it's the pump?) started running. The only way to get it to stop is to disconnect from shore power.

Any thoughts, ideas, suggestions...

"...pretty sure"??? Why not definitively? Do you know where the pump is? Do you know where the pump switch is?

Without water in the fresh water tank, I am "pretty sure" it cannot build pressure.

Find the fresh water pump switch. It is likely ON.

There is usually a pump switch(on/off) located in the wet bay as well as inside the coach in the control center. You might have accidentally switched it on when you winterized it.

Did you have to turn pump on to drain water tank and perhaps left it on?

Get a voltmeter and pull the connector pin and verify the switch is working (on/off) I bet it is just left on by mistake.

The real question is: why does someone in Winter Springs now need to winterize? Last weekend was the sub-freezing cold snap.

Shore power shouldn't have anything to do with the water pump, as the pump is DC and shore power provides AC. Unless your coach batteries are dead, and the converter is providing DC power only.

OK -should have provided a little more info
* so no i'm not 100% sure where the pump is
* the pump switch in the coach is definitely not on
* didn't know there is a pump switch in the wet bay (will look for it)
* connector pin? voltmeter? - not really in my wheelhouse
* moved to NC last year to babysit grandson (updated profile)
* coach batteries are good

So I think the issue is that there was no water in the fresh water holding tank since I now the pump switch inside the coach is definitely off.

Thank you everyone - especially the honestly helpful posts!

You would have to know where pump is in order use a voltmeter on the connector pin that supplies power to the pump from the switch.

But let's shift gears since that is not in your wheel house.

You say "the water pump (pretty sure it's the pump?) started running." can you take picture of what you hear or where the sound come from? Not questioning you but what make you pretty sure it is the pump if you don't know where the pump is?

All we know for sure is that you have something running and when you turn off shore power it stops. Think of it this way, if water pump switch or pump itself was somehow defective and drawing current; would run 24/7 until your batteries drained dead.

My guess is that you may be hearing the converter running to charge batteries or something which would be perfectly normal as long as you have shore power. You unplug the shore power and it stops

FWIW you winterize like me using the air blow method

THOR WINDSPORT....
The water pump is DC powered. In my unit, the water pump is under the dining table seat...find it on your unit. If running, turn it off in the control panel.

The disconnect of the AC shore power is not related to the DC water pump.
I suspect something else is making the noise.
