To all my fellow campers suffering from check valve failure on ShurFlo 4008 series pumps. Symptoms are frequent pump cycling with no apparent leaks and/or city water backfilling the FW tank. The steps are:

Order ShurFlo check valve replacement kit P/N 94-800-03
Remove three screws
Remove and replace three plastic parts and one spring
Reassemble and reinstall three screws
Check for leaks

Ten minutes if you're slow. I didn't even have to remove the pump. Simple fix when the standard "recycle to remove sand" procedure doesn't work.

Thanks for the walk through.. I replaced the entire front housing on ours a few years ago.. because of a failed pressure switch.. was easy peasy.
