How to Extend a Basement Floor Drain

What You'll Need
Circular saw
Hole cutter
PVC plumbing pipe

Drain cover

If you have a basement floor drain, you might be interested in finding a way to extend it so you can relocate it to somewhere else in your basement. Your basement floor drain will typically be located in the lowest area of your basement. However, you might also want to install a second basement floor drain next to your washing machine or water heater. In this case you will want to find out how to extend your basement floor drain.

Step 1 - Choose the Location

You must first decide on the location for your new basement floor drain. Once you know the location of the drain, you can measure and check that you have the right length of pipe required.

Step 2 - Drill the New Basement Floor Drain

Use your hole cutter and drill to cut the hole required for the drain. Cut the hole to the right depth required for the drain. Remove the concrete by using a chisel. (You could also use a normal drill bit to break the concrete into smaller pieces if required.)

Step 3 - Cut the Trench

Next use the circular saw to cut the trench where you will run the pipe. Cut through the concrete slowly and make sure that you are as accurate as possible. After you cut the trench, you can break up the concrete with a drill or chisel. Then remove the concrete from the hole so you can lay pipe.

Step 4 - Lay New Pipe

Start by covering the bottom of the hole with a small layer of sand. Then you can lay the new length of PVC pipe. You will need to connect the new pipe to the original drain. If you can't connect it, replace the drain with one which has another connection. Connect into the new drain so that it's watertight. Use sealant to seal the gaps if necessary.

Step 5 - Check the Basement Floor Drain

Before concreting the basement floor drain, you should spend a couple of minutes checking that the drain works properly. Pour some water into the drain and check that it doesn't leak.

Step 6 - Concrete the Pipe

Now you can place a layer of sand over the pipe and use concrete to seal in the pipe. After the concrete dries, put the cover on the drain and  try it out again.
