## Combining Two Kitchen Sink Drains
### Introduction
In a typical kitchen, there are often two sinks, each with its own drain. This can be convenient, but it can also be a hassle to have to deal with two separate drains. If you’re looking for a way to simplify your kitchen plumbing, you can combine the two drains into one. This is a relatively simple project that can be completed in a few hours.
### Materials
* Two sink drains
* Two drain flanges
* One drain trap
* PVC pipe and fittings
* Teflon tape
* Plumber’s putty
* Adjustable wrench
* Hacksaw
### Instructions
1. **Turn off the water supply to both sinks.** This is usually done by closing the valves under the sinks.
2. **Disconnect the drain pipes from the sinks.** Use an adjustable wrench to loosen the nuts that hold the drain pipes in place. Once the nuts are loose, you can pull the drain pipes off of the sinks.
3. **Remove the old drain flanges.** The drain flanges are the metal rings that are attached to the bottom of the sinks. Use a screwdriver to remove the screws that hold the drain flanges in place. Once the screws are removed, you can pull the drain flanges off of the sinks.
4. **Clean the sink drains.** Use a brush and some soapy water to clean the sink drains. This will remove any debris that could clog the drains.
5. **Apply plumber’s putty to the new drain flanges.** Plumber’s putty is a type of sealant that will help to keep the drain flanges in place. Apply a bead of plumber’s putty around the outside edge of each drain flange.
6. **Install the new drain flanges.** Place the new drain flanges over the sink drains. Make sure that the plumber’s putty is evenly distributed around the outside edge of the drain flanges.
7. **Tighten the screws that hold the drain flanges in place.** Use a screwdriver to tighten the screws until the drain flanges are snugly in place.
8. **Connect the drain pipes to the drain flanges.** Use an adjustable wrench to tighten the nuts that hold the drain pipes in place. Make sure that the nuts are tight enough to prevent leaks, but not so tight that you damage the drain pipes.
9. **Install the drain trap.** The drain trap is a U-shaped pipe that helps to prevent sewer gases from entering the kitchen. Place the drain trap under the sink and connect it to the drain pipes.
10. **Tighten the nuts that hold the drain trap in place.** Use an adjustable wrench to tighten the nuts until the drain trap is securely in place.
11. **Turn on the water supply to both sinks.** Check for leaks around the drain flanges and the drain trap. If you find any leaks, tighten the nuts until the leaks stop.
### Tips
* If you are not comfortable working with plumbing, you can hire a plumber to combine the two kitchen sink drains for you.
* If you have a garbage disposal, you will need to install a separate drain pipe for the garbage disposal.
* You can use a variety of different materials to combine the two kitchen sink drains, such as PVC pipe, copper pipe, or PEX pipe.
* Make sure that the drain pipes are properly sloped to allow water to flow freely.
