Fresh water tank back filling thru pump

Adding a check valve seems like a hack to me. If the internal pump check valve is leaking, that means the pump isn't working to its full potential. It uses check valves to push the water toward the outlet.

Exactly.....

2016 RV so most likely plastic debris from fresh water tank/pump installation

Use pump for water needs instead of city water and use up the WHOLE fresh water tank.
Then swap back to city water-----disconnect suction line on pump and see if it still is back-flowing thru pump

If it still is.......warranty/replace pump

OR

buy a $15 in-line check valve and install it in suction line.
(Shuflo makes an in-line)

Cheaper/easier then pump rebuild

Simply turning the pump on may dislodge the particle that is causing the check valve to leak.

Is this new? Some RVs are designed to do this.

You must be braindead.

local DMV had a sign that said

"NO WIFI"
Available

I inquired about this "NO WIFI" that is available, to no avail...

I've never pumped "holes" - must be something new in campers. :W

You haven't provided any pump details but if a failed check valve in the pump head is truly the problem I'd just add an external check valve and be done with it.

Looks like you don't have to replace the 'hole' pump.
