When installing a sink in your basement, you have a number of options when it comes to the type of sink. If you're going for half-bath basement, installing a standing porcelain sink will do the trick. Or a counter-top sink is perfect if you have the space. For a more practical approach, a laundry or utility sink will work if you have your washer or dryer in the basement.

Let's say you want to install a counter-top sink in your home.

Connecting the Lines

Connect the supply lines to the sink. If you're working with a counter-top based sink, you can use silicone caulk before fitting into the sink. Once the sink is in the hole, use caulk around the edges, and trace along with a wet finger to smooth out the edges. After inserting the faucet, connect the supply lines. The supply lines connect between the new faucet and the main plumbing of the house.

After tightening the screws from inside using the sink using pliers, there should be two rods that will hold the faucets in place. Afterwards, connect the supply lines to the main shutoff valve.

Installing the Drain

You're going to place the drain in the sink using plumber's putty to avoid water leaks. After measuring the length of the drain pipe, cut it with a hacksaw, and connect to the drain assembly. The drain nut will go on the bottom. A trap goes to the end of the pipe with a coupler, and be sure to seal any non-threaded pieces. The trap will go to the main plumbing line using PVC glue and a union connector. Turn on the faucet and check for any leaks.

Installing With a Drain Pump

You can install a trap in the drain line that goes between the pump and the sink drain. This will help in preventing foreign objects from getting into the pump. Whenever you're working with any type of plumbing in the basement, you're working against gravity since you're building below the sewer line. In my last article about installing a basement in your toilet, I talked about the macerator up-flush toilet, but when it comes to sinks, a sink pump will be the next best option. A 15 amp pump is your standard system to use. You can get a pump from your local hardware store, and it normally costs around $150.

The sink pump will come with instructions, but here are some of the basics when placing a pump under the sink.

Start by inserting the tee fitings into the nearest water lines.

Water valves will go on each of the lines, along with a flex hose that connects to the faucet. The PVC pipe goes from the sink drain to the pump. From the closest drain line, connect the tee fitting and place into the pump unit. PVC piping will connect from the tee to the pump. About a foot from the tee fittings, a check valve will go in place to prevent any water flow when the pump is not in operation. A check valve will look like this.

Make sure all the couplings and fittings are cleaned before applying pipe cement. Once you connect the drain line to the pump, connect to a power supply. Once it is ready, test the pump and faucet for any leaks.

The above steps are a few ways to install a sink, but you can use what works best for you.
