I have a RoadTrek 170 Popular. The water pump continues to run after I turn of faucet. I took of the filter and cleaned it(it wasn't really dirty). Nothing looks cracked. Pump still continues to run. I might add that water comes out very slowly when pump is on. Water comes out fast when on city water. Is there another filter somewhere?? Any other suggestions?

I did an experiment. Turned on city water then turned on pump pump ran for 3 or 4 seconds then shut off.

Seems to me there is an air leak somewher but I am not leaking water anywhere that I can see.

Hard to pinpoint without finding a trickle somewhere.
Check the fittings at the pump itself, and make sure the strainer is securely tightened. Maybe the seal on the strainer?

Also check the water heater connections outside (and inside, if you can get to them) at the anode and the pressure relief valve. If the P/R valve is slightly askew, it might be leaking air into the w/h tank.

Short of that, start tracing the PEX tubing and look for bubbles if it's transparent, and still clear enough to see inside.

Check your wet bay and be sure all valves are in their proper positions.

If you have a 4 way valve called "Kantleak" for switching from city water to pump, it may have failed washers inside. They notoriously go bad. A rebuilt core can be had for $36. Easy replacement without disconnecting any fittings

2007 Roadtrek 170s don't really have a wet bay, but you might check the tank fill/city water (red?) valve handle located near the shore water connector/external shower hot/cold valves. On my 2002 190P it had to be in the vertical position for normal use, and horizontal for tank fill. Turn it to the vertical alignment.

I don't think they have such a device. I may be wrong.

Sounds to me like the pickup in the FW tank is loose or broken or there is a vacuum in the FW tank.....

Agree^^ to check the valve position.

Your problem is consistent with the valve allowing water to circulate back into the tank when on pump only. That’s why the faucet flow is low and why the pump never shuts OFF—the pump cannot build enough pressure in the lines to trip the pressure switch because water is flowing in a circle to the tank. When you connect to CITY water, the lines are pressurized and with the pump ON, the pressure switch is tripped because the pump is pushing against a high pressure line, coming from city water.

Don’t know your valving set up, but check that it is properly set and that the valve that diverts water between CITY and TANK completely separates the two sources with no cross flow.

Thanks everyone for the replies. Turns out it is user error. I read the manual to say turn valve horizontal to fill tank and interpreted it to mean keep it in that position. I had to turn it back to vertical after tank was full. I stopped at Schaaps Travel Land in Sioux Falls SD to have them look at the issue and the tech showed me the valve was in the wrong positon, No charge. Nice people.

Someone mentioned that 5 days ago.
