x2. That pump should be covered by the pump manufacturer warranty and usually a mobile mechanic can do the work.
Have you tried resetting the check valve by
1) Turn off city water at the source;
2) Turn on your water pump and open-and-close various faucets in your camper allowing the water pump to cycle on and off;
3) Turn off water pump, open a faucet and relieve water pressure;
4) Turn city water back on.
Might not work, but it couldn't hurt to try.
The other suggestion would be to replace the check valve that's usually located under the kitchen sink.
