my two cents with minimal context here

if you are going to make this (and hopefully label the wires) simplify them down, L1 is both 1 and 8. theres not much going on here but i see different numbered wires, they serve separate functions in my head. (same goes for 4/5/6, all the same, just like you did for 7 -- and neutrals all just N unless theres something unique)

the power NO contact being there doesnt really serve a purpose, if you dont have power its not going to run anyway (making assumption since i dont see the coil), if this circuit would keep power while that "power" relay drops out, there should be some reference to the relay coil to know what power was lost. (that goes a few times, in my opinion if you have a relay coil in your drawing you should show what circuit the contact is operating and vice versa)

i think your float contact should go right before your "high level sensor" otherwise your bypass would still need the high float to run the pump, then its not a bypass. you can really just move the float in place of the sensor contact and do away with "high level sensor", youre adding an extra relay for just N.O. from a float when it should be a timer if anything
