I have two chugger in line pumps. At first they both worked fine. Now all of a sudden one of them doesnt work. I searched the forums, and found that it could have been the impeller and the tolerancing. So I followed the same instructions and bored out the impeller to 17/64". I did this to both of my pumps and the one still works fine.
Now I took the one that doesnt work off my stand and took it apart. When the pump head is not attached the motor runs and works perfectly normal. However, when I put the pump head back on, and try to pump liquid, the motor doesnt even turn.
Can anyone help me with this issue, or am I going to have to buy another pump?
Thanks in advance!
