Primer pump higher than resovior?.

[keithmac]

Hello all, I`ve been re-installing my WI system and found the only feasable place to mount the remote primer pump is actually above the water level of the resovior.

Just wondering if anyone else has done the same and if I have primer/ main pump/ checkvalve in that order would the water be likely to syphon back into the lower water resovior, or would the checkvalve and main pump stop that from happening over a period if time?.

I`m wiring it up again tomorrow night and will keep and eye on the lines, just interested to here any opinions.
