Final Walk-Through - Yes or No?

[Max James]

What would you do?  I just had the seller fix over $1500 worth of plumbing issues (tore into a wall to fix a waste stack and did a few other things).  Should I do another walk-through directly before the closing just to make sure the water is running properly without leaks?  And that the job was done well?  Or just use the sellers receipt they sent as proof everything was done well.  There's a 90 day guarantee on the receipt.
