The broken PVC story from above reminded me of a story from my last house. This was a repair but it was on something that wasn't broken...just old.
My current house is a piece of junk, but my last one was rock solid. 11 years of ownership, almost no problems. I didn't know how good I had it at the time.
We put the house up for sale and the realtor came over and went through everything. Recommended a few minor repairs, none of which were an issue. One thing she seemed to focus on was the sump pump. Our sump tank was in the sub-basement, which was laundry/water heater/furnace/storage. Still a decent sized room, probably 25'x15'. Concrete floor with an old piece of carpet that was there when we moved in.
Realtor says "that pump is really old and you don't want it to give out while you're trying to sell the house." Pump has always worked flawlessly, but you're the pro. I replace it.
A month or so later, house is under contract. I'm out picking something up I had bought off Craigslist in preparation for the move and the better half calls. "There's water in the basement." What? How? We've never had water in the basement.
I get home, there's an inch of water on the floor. WTF? The new pump isn't running. And it's pouring outside. Back to Home Depot to buy another pump, and now I'm fighting the tank filling up while I'm trying to replace this stupid thing. I'm basically working underwater. Infuriating, but I do get it fixed.
All of the storage was raised so there wasn't really any damage, except for that stupid carpet. No pad, just some old carpet. Looked like it came from a business after they ripped it out.
I didn't want to get any strange questions after the walkthrough about "where did the sub-basement carpet go?", so I drug the now super heavy carpet into the garage, put it up on blocks/ramps/anything I could find to get it off the ground, doused the entire thing in Febreeze and let fans run on it for a few days.
Sub-basement smelled like the inside of a Febreeze bottle. I never told anyone and no one asked.
Why did I replace that pump?
On the bright side, Home Depot did refund my money AND gave me a replacement pump.
