After the 2011 flood, I cleaned the tank (250 gal).and and clorinator tank(25 gal). for our community water well. Got the well going just as soon as the water went down to help people clean out cabins and that is working fine. My clorinator injects a small amount every time the pump comes on. Just cut the wires on it at that time so it would not run. Now yesterday I wired it back up and it runs but I cant get it to prime up and inject clorine. Is there some trick to get it primed back up. Tried taking a water hose and front flush to prime than tried back flush still nothing. We paid $850.00 last sept. for this new clorinator pump. It did go under water for about a month but it seems the motor is working, just not the pump. Any thoughts would be appeciated.
