Water recirculation setup

[Harrison Ho]

Hello. I just had a water recirculation pump installed but I'm not sure it's correct. The end point takes about 2 minutes to get hot water so the pump was installed to fix that. It's still taking a while to get hot water so I'm not sure it's correct. Can you see any big issues with this? Thank you

1. There must be a hose bibb at the bottom of the tank to allow draining so FAIL there.
2. For a pump to do anything there needs to be a dedicated return line or
3. a bridge ("Grundfos bridge") at the far fixture and in that case the entire job is a failure anyway.
4. we always put isolation and bleed tees on both sides of the pump

no professional trained in plumbing did that and they should be schooled before going out into the field.
NOTHING WITH THIS IS RIGHT

Did you add any "comfort valves" under any sinks?

What a mess! The pictures seem to indicate that this installation is taking suction from the bottom of the water heater and pumping it into the cold-water inlet of the water heater. Is that what I'm seeing????
