Compost Tea Brewer - 5 Gallon Mini Microbulator Reviews

Just got mine today, watched Tim's video on YouTube and read the instructions. Excited to get some tea brewing. Set it up, have two gallons of water in my homer bucket,, but the water is not making it up the return. Maybe I'm doing something wrong, but it seems hard to do that, and I work in IT so I'm good at figuring things out. Hopefully this will be resolved quickly. Thank you
