Help ASAP - priming a Rena XP 3
Getting ready to take a trip and decided to clean my filter. Emptied it, rinsed it, filled it back up almost to the top, hooked it up and let it fill, plugged it back in. All same as usual. But there's air coming out of the jet spray. Tried priming it but it's been so long since I've primed it (4 years ago when I set it up), maybe I'm not doing it right? I turned the filter off, poured water into the back of the intake till it over flowed a bit, capped it and turned it back on. Still air. I tried tipping it this way and that to get the air out. I dunno what to do and I honestly am really pressed for time. Help??!!??
