Wait... a rep told you to install the connector vertically? Are you serious??
Not no but hell no. I've been out on over 50 warranty calls that were due to messed up drain installs. Most common issues were:
- Both no high loop and no air gap (plastic double hose bracket tossed aside because no one knew what it was for).
- Y connectors hacked with a utility knife (more common than you'd believe).
- Vertically installed Y connectors with the double ends facing down (Can you say "G-R-A-V-I-T-Y"?)
By the way, check valves work great under pressure but often seep when in a (very gentle, no pressure) gravity feed situation because the water isn't really pushing on the rubber flapper. Without pressure pushing on the flapper it doesn't seal very well and the water can then gently, slowly, seep through.
