PVC is not too hard to fix usually...you get a coupling of the right size..(that the pipe will fit INTO)...then the bad section has to be cut out and the union fitted in....(there are several 'possible' ways to bridge the gap...depending on whether you can move the visible part of the line or have to use a union) hard to say without seeing it.

The important part is, there is a two-step chemical trick to seal it...has to be primed with "purple stuff" (softens the surface) then coated with standard PVC cement and slid together. Not hard to do, but has to be RIGHT...(you only get 15-20 seconds to get it positioned before the cement sticks)....the parts to fix it, if I understand it right...including the chemicals...would only be less that $10, I'd think....if you know ANYONE who has done air lines or water lines this way, get some help and do it yourself. Wish I was closer...
