    If you’re running it in a test tank or lake with cool / cold water, you
    should be able to feel the copper water line by the powerhead
    and feel the cold water pumping through.
    Also, some people drill a tiny hole in the lower elbow where the
    copper line attaches to act as a “Tell – Tale” to see the water
    shoot out.
