Last week my and my boss went on a quick service call. Our company had plumbed a house 7 years ago. The owner of the house had a sewer back up in his house, we installed a slice gate and a backwater preventer and in addition two sump pits with working pumps in the initial contract
He claims both pumps failed and so did the check valve/backwater preventer. Note this is a 7-year-old job. He wants us to pay for his water damage from the backed up sewer.
Here is the key though. We went in to inspect after the matter and found the flapper on the check valve was floating above the screw on cap inside the pipe under the floor. Now this is very odd. He claims we forgot to put this flapper back in, and that is just almost impossible when I think about it.
I think this fellow took it out and placed it on top of the screw cap so we would be at fault for his sewer backing up.
Any thoughts on how to deal with this?
Our warranty is only for one year, and this was all inspected and passed by the local plumbing inspector, who is to say a drain cleaner or even the owner did not remove this flapper.
