Indeed, that's why I said fitting the NRV upstream of the pump. It would do no good downstream as that's not where the pressure is being lost to. My only concern (as I think George was alluding) is whether the pressure switch senses outlet-to-ambient, or the differential across the pump. If the latter, it would just keep increasing pressure until something gave way.....
