You need some soap through the water supply system. About the only thing that would be affected would be the impeller in the water pump. Those are available as replacements.
In my days on tankers moving petrochemicals, gas stock, and various oils, our line was "that can't hide from intensified Tide". We used boxes of the stuff to get product off of where we didn't want it. I wouldn't recommend powdered laundry soap for cleaning a water supply in an RV but the principle is the same. Soap will remove the gasoline from your PEX lines.
