Ha ha, yeah, no water, no drains.
Just want to get enough water for the drain inspection and will reinstall the pressure tank etc after a new slab is poured.
It is a 2 wire pump, 240 volt. So I'm going to try direct wiring it to the circuit breaker box and use that as a switch.
If the pump does not come on when the breaker switch is connected, something has broken since the pressure tank was removed for the demolition.
Even with the pressure tank empty and disconnected, the water still flowed when the breaker was switched on, but then we removed the tank and tried to just get the pump to work with the pressure switch disconnected with no luck. I didn't try to manually join the contacts in the switch with a screwdriver, seemed too dangerous to me. But don't know why it would hurt to just wire it up directly and briefly turn on the water with the breaker switch.
