Dewinterized, what are we doing wrong?

Question

We hooked up to city water here at home. Flushed out the pink stuff by turning on all the faucets, shower head, and flushed toilet. Water is coming out of the syphon  tube we used to pump in the antifreeze.  Why? Where is it drawing water from? When I turn off the city water it stops.  Thanks!  We must be missing something obvious.

The city water has to be back feeding through the pump. If it was not coming out the siphon tube, it would likely be filling your fresh tank.Jerry

Thanks, we will look for a valve. I'll let you know!

There's a check valve built into the fresh water pump that's stuck or failed. You can try putting water into the fresh water tank and running water through the pump. That may flush out the crud.

You other choices are replacing the pump or adding a stand-alone check valve (a.k.a. backflow preventer) on the pump fitting.

Over the decades, from time to time, I've had pump check valves get stuck. I'd take them apart, run water over them, put them back together and they worked again. Never saw whatever was making them stick. Apparently the little fine screen filters in front of the pumps don't catch everything!
