"Our sump pump was working when we moved in but about 9 months later we had a week of heavy spring rains. I realized I hadn’t heard the sump pump making noise for a while so I went into the garage to check the 3ft crawlspace we never use which runs the length of our entire house. I kid you not — we had a 2ft deep swimming pool under our home. We spent $7k on getting the water pumped out, mold mitigation, getting a vapor barrier installed, and replacing the sump pump with one that has an alarm.

The old sump pump was the cheapest one our plumber had ever seen. Would’ve been nice if our home inspector had bothered to mention it."
