Hi,
I noticed there is another post with similar situation where my Pentair Whisperflo frozen during Texas freeze and now I find some cracks on my pump. See the attached images.

Im trying to apply epoxy along these cracks and am waiting for it to cure to see if that would work. I also realized this is just band-aid as eventually we need to replace the volute. So my question here, with these type of cracks, would epoxy sufficient? If I have to replace the volute, is it an easy DIY or really need professional to do it? Have anyone replaced volute? Any recommendation or suggestion on how to do so? I am hoping I can DIY as we slowly found cracks here and there after the freeze and they added up.
Thanks..

use your part number off the pump and order a new volute housing and replace. it doesn't look overly complicated if you are mechanically inclined. there are also youtube videos on how to do this as well.

The volute is held on by 4 bolts. You can see the disassembly in this video...
