Can I Run 3 Phase Motor On Y Or Star Connection Without A DELTA?
Some motors need a Y and Delta, with a special switch, to start up, you start with the Y. the motor starts turning, but does not give full power. after a few seconds (depends what the manual says) you switch to delta, to get full power. To let it run on full power in Y you need 1,4 times the voltage.
If everything runs fine, you won't have damaged anything.

I replaced my pressure switch with one that has a emergency low pressure off switch.
There are a lot of variables. Are you on a shallow well pump? It sounds like the well doesn't make much water. Check your well tank pressure. With 0 psi of water (drain the pressure) There should be 2 psi of air less than than the start up. If the pump is set to start at 30 psi, there should be 28 psi of air in the tank. It sounds to me like either the tank is shot, or the pump doesn't make much water. If you leave a faucet on while putting air in the tank and air comes out the faucet, then, the bladder is shot.
