I think its possible the wires got damaged or came loose. I'm hoping its just loose wires and that tightening them will fix it. But I really do need to fix up the system. Need to flex seal the roof of the shed, remove un-used cables, get some working GFCI outlets in there for lights, add a disconnect box for the pumps, etc. I'd like to figure out how to add some sort of sensor so if the cistern's water is empty or too low the jet pump won't try to pump air. I also want to add a shutoff before the pump so I can keep water from pouring out while working on the pump. Right now that is tough with all the couplings though. Also want to raise the pump so it is above or even with the inlet side pipe. Want to put an anti-fatigue mat under the pump so it dampens the vibrations a bit.
