I bought this from you quite some time ago and am setting it back up on my new setup. When I installed it over a year ago, you had a great video describing how to set it up that is different than the video that is now on your website. The previous video referenced installing one float valve upside down to serve as a safety to prevent overflowing. Could you please refer me to this as i cannot find it anywhere and don't remember how it was exactly setup. Thanks
