Shurflo 4008 seize ?

[steve J]

Just went and hook up 4008 pump. And I hear it click for it to come on but nothing happens? This would be third season could it be seized?

Run some warm water in it, then try again. Most likely the diaphragm is just stuck. You may want to run hot water in both ends, let set a minute or so, dump it, turn pump over and repeat on the other end. Then hook it back into your system.

Might be something in the pump too.... They are easy to pull apart to see what is going on...
