I tried this way back but the one way valve I used must have been a restriction, I lost around 20 psi when priming with an electric drill. I removed it and never bothered trying anything else, just went to priming with a drill as part of the start procedure. Of course you may have a less restrictive valve but it's worth checking.
For info we are using a dual line, I only lose prime after 6 or so days, any time before that, the load is already on the drill. HTH's
