It would seem that I've got a little situation on my hands. I came home from lunch and noticed that the pump pad was wet, and traced the leak back to a crack in the pvc return right after the filter.
This picture is to illustrate the area:
And a closeup of the crack. I didn't have my camera on me, so the red line is an artist's rendition of the crack:
It didn't seem like it was leaking real bad. The pump was on for a few hours and the pad wasn't even soaked. I turned the pump off until I can figure this out.
What are your thoughts on the best way to fix it? I suppose the best solution would be to replace that section of the pipe. However, are there any mid-term or even short-term solutions that would work? Some sort of PVC epoxy or compound? Please let me know any sort of input you have.
