i have seen tanks with flexible lines rock easily just by touching.
motion might cause a flex line blow out

If the heater rocked when touched, I think there would a problem other
than flex lines. Our code now requires an "earthquake" strap. I
skipped that step for now..

self installs are rarely code compliant. a good friends husband used
the flex couplings the heater can easily rock, he didnt bother putting
a line on the TP valve, saying it wasnt necessary. major scald issue,
the TP points toward a hallway of sorts in the basement

a real hack job that could hurt his family
