Fred replaced the sump pump immediately hoping it was just a high water table, but when that didn't work we had to call the town crew in at 9:30 at night.
They tried to turn off the outside water at the street, but the valve sheered off so we were stuck with this running water all night. Luckily the sump pump was able to keep it at bay, even if it meant running every 60 seconds.
This morning the town brought in a huge hydro vac truck to dig out the shut off valve to keep the water out of our house. Success! The town had to pay for that work, but now our part starts at $280/hour.
We have the crew digging under the deck right now trying to locate the water line, but so far no luck! Will keep you posted!
