True DIY work can sometimes not be up to par with the pro's. On the other hand I've had "pro's" majorly screw up stuff. I then had to fix it myself or fight them to fix it right.
You could, for a few days, turn the watermain off in the house before you leave. Then at least you wouldn't come home to a pool in your living room.
My latest issue was with the pipes leading to the house. I still have a big hole in my yard to make sure it doesn't leak. Everything looks good for me so far. I did do a similar repair years ago with no problem.
It sure is a lot easier to just "pay the man." But even that doesn't always turn out good.
