I have a 2026 310RL Paradigm with a regular tank water heater and the water manifold system. I'm wanting to sanitize the fresh water. I found the syphon hose but I can't seem to find the water heater by pass.
I'm assuming you mean 2026 since Alliance didn't exist in 2016 and they recently started doing manifold on the paradigm line. It should be behind the panel on the pex. The white in the background of this image is the Styrofoam insulation on the water heater tank.
