Has anyone replaced the sump pump in a Glacier pool chiller? Mine is not turning on. I have checked to make sure the float is still working, verified power is good to the current pump, and manually tried to activate the float with no success. So I ordered a new pump (it was only $135), but now I have to figure out what I need to do to get this old one out and put the new one in. Seems like there is really no one in Houston who works on these things.
