We purchased a new hot water heater from Lowe's, a subcontractor came to install it and drained our old hot water heater down our basement drain, clogging it. We had a huge flood of sewage in our basement and a third party confirmed it was because of the silt and sand from the old hot water heater.
Initially Lowe's said they would pay for everything but then they turned us over to their insurance, which turned us over to the subcontractor's insurance, which refused to pay. Now we are on the hook for almost $4000 and have to go to our own insurance, which will raise our rates.
Lowe's guarantees their work and has contracts with all their subcontractors, but when one of them messes up, they suddenly say it isn't their problem. They're despicable.
Monetary Loss: $4000.
