Well I am not to big of myself not to admit I made a mistake. About a year and half ago I had a home owner call me about their backwater valve in the basement has failed and needs to be replaced or some sort of new flood control system installed. I looked things over located the sewer line, and water line since they both are in the same trench. We installed the Clean Check backwater valve into the 6" clay sewer. The job was inspected and passed, we then backfilled the hole and that was the end.... So I thought.
Back during these big rains the new owner of this home said she got my # from the previous owner which told her I installed the Clean Check backwater valve. That during the last rain she got water. I went out there and check on the Clean Check, it was in working order. I told her I can try to investigate some more but from what I can tell the Clean Check is doing its job. Maybe the drain tiles tie into the sanitary under the house instead of the front yard like most of the homes in the neighboring suburbs have. This was back in July when we got the big rains in the area. I have not heard from her since.
Today I get a call from the towns plumbing inspector asking to meet me on site this afternoon. He explains to me this town even though the homes are 50+ years old the down spouts ran to the storm sewer, and he feels I put the Clean Check on the storm sewer line. I was like that is imposable I located the sanitary sewer from the old back water valve and pinpointed the spot I dug. Came across 6" clay and installed the valve. That he even inspected it and passed it.
So I ran my camera back towards the house expecting to see the 4" CI x 6" clay transition and then the old broken backwater valve body in the basement. To my surprise I see a 4" pipe teeing in from the left and a 4" clay pipe in front of the camera as I pushed the camera down the 4" clay it back super clear I am in the drain tiles around the house. I was flabbergasted, I had no idea these houses had separate storm and sanitary sewers, and both happen to be in the same trench. So Monday I have to dig this sewer back up and relocate my backwater valve on to the sanitary sewer, and repair the storm line.
I am still in awe about this. All the neighboring villages have combination storm and waste sewers. Most of them you rod from the front downspout to open the main line. But not this town they had their head screwed on straight when they first built out this area. But what good has it done for them during the big rains they had 1000's of homes, streets parking lots all flooded.
So anyways, any of you all have to go back to a job and make repairs on your own dime?
