Hey guys.I am in the middle of finishing my basement. We have a floor drain in the middle of the room that I am wanting to cap/plug and cement over so I can put flooring down. We have had our basement flood 1 time when the sump pump went out and the water came out of this drain. We replaced all the drain tiles around the basement and the crew installed a new drain over by the washer/water tank and its on the other side of the room from the sump pump. The main purpose of this drain was a gravity condensation drain for our HVAC, for which I've already installed a condensate pump.

My question is, what is the best practice in plugging the drain and then cementing over? The pipe measures 3 inches in diameter on the inside of the pipe. I want the plug to be lower than the floor so I can cement over it and have a level floor. I've included pics of my piping and flooring to give you an idea of what I am looking at. The floor does slope slightly around the drain so which I am going to use the self-leveling cement.

Any input would be great.

 

That is PVC piping so you can glue a short (2") long piece of pipe into the fitting in your floor. Then use an inside cap or a test cap. Most of the caps you find at home center will be big caps that go over the outside of the pipe but you want the more rare cap that glues into the inside of the pipe. This could cap it off almost flush with the fitting in your floor.

 

Did it have a flange around the outside that would have been flush with the floor, looks like a floor drain fitting so the dia is not a pipe OD size, 3" pipe is 3.5" OD.

 

Hey Marq1, it was a drain grate. It just sat on top of the pipe and was flush with the floor.

 

You definitely want something to glue into that otherwise there will be the chance of a leak. That dia is going to make finding the right size plug/pipe more difficult. I don't know every fitting that is out there but try a good plumbing outlet, they would have a larger selection!
