When water is allowed to sit inside the unit, it can freeze in the high pressure port, and crack the Sump Base. Sometimes it is difficult to see the crack, but it will be there. Sometimes it is easy to see the crack. The Sump Base must be replaced.

Here is an easy one to see:

This one was not so easy, crack detection dye helps make it more visible. I bead blasted before using the dye on this one to make it more clear.
